Power Sensor Support & Power Zones

Ready for some Power? We are! Cranking up the Watts just makes you feel, well, powerful. And according to science, there is no more accurate version of calories burned than Kilojoules, something you can only get accurately by measuring watts. For cycling, it is the rage, and for good reason. If you are interested in learning more on the history and the power revolution, listen to this great podcast with Hunter Allen at VeloNews.

So let’s jump right into the nitty-gritty. The requirements are pretty basic – a compatible BLE Power Meter, an iOS compatible device with one of our apps installed and a Star Membership.

Pairing your Bluetooth low-energy Power Meter

Menu > Sensors > Power > tap the + sign while engaging the power sensor (turning the crank)

Tap OK to pair with the sensor.

Note: If there are multiple sensors found, like if you are in a Spin(r) class, you will also see a proximity meter next to the sensors. Typically the most powerful signal is the one closest to you. Tap that sensor to pair.

Running a Workout with Power

Once your sensors are paired, simply hit the play/go button on the activity type you’re using the sensor on, or chose any number of ways you can start your workout / workout routines. It will acquire the sensor as you activate it, and begin the workout. If you want different data then what is shown on the default dashboard, you can easily setup custom dashboards, even one just dedicated to Power metrics. You also can swipe to a Power (Watts) graph, with Power Zones if you have set them up or done a Personal Power Assessment.

Setting Up / Editing Power Zones

Creating and Editing Power ZonesSetting up Power Zones is easy, and allows you to start designing workouts specifically targeting different systems and improvements. You typically want to personalize your zone set (see more on the Personal Power Test (PPT) below) to customize your zones to your current fitness level (we are not fans of default zones here!! We are all individuals and very different, and we respect that!). If you are familiar with customizing and managing heart rate zones, it’s the same process.

Select your activity type for the Zones, tap the Gear / Activity Options icon.

Under the Preferences section, tap Dashboards & Zones. Then tap Power Zones > Add Zone Set

Tap the title to change it, change the values on the right to modify them, tap the zone name to change those if you want.

Edit Power ZonesTap Save to save the set. That will bring you back to the Zone Set list. Tap again into the details and tap Set Default at the top if you want to use that zone set as your default.

To delete a zone set, in the Zone Set listing, tap edit, then tap the red delete icon on the left.

Personal Power Test (PPT) – Power Zone Assessment

Training at various intensities gives specific physiological adaptations. The most accurate way to categorize intensity ranges is by measuring the work-rates that cause various physiological responses. Power Zones are based on a percentage of a rider’s baseline fitness marker, known as Personal Power Threshold (PPT). PPT represents the rider’s ‘work-threshold’ or their current level of fitness. With power meter technology of the Spinner® Chrono or the Crank, the result of a relatively simple and straightforward test can accurately establish your PPT. Once determined, riders can train in their unique ranges based on a percentage of their PPT. Since power is dynamic and improvement in fitness will increase PPT, it is important to retest quarterly (or sooner) to track progress and re-establish zones that match the rider’s current fitness level.

Personal Power Test AssessmentThe Personal Power Threshold Test (PPT Test) is a sub-maximal, repeatable test to determine PPT. It is:
• The personal results of an individual rider
• A scientifically validated incremental test
• Easy to learn
• Repeatable and Reliable
• Sub-maximal, and so can be performed by nearly everyone

After a 10 minute warm up (you can skip this by double tapping on the screen at any time), the test consists of back-to-back two-minute stages, in which the rider sustains a cadence goal within 5RPM of the target, while remaining a seated position, in Hand Position two. The first stage begins with light resistance on the flywheel. Each corresponding stage begins by increasing resistance, while keeping cadence and riding position the same.

The added resistance should be enough to feel the change, as if increasing RPE (Real Perceived Exertion) to the next level. This also noted as increased wattage. Since individuality and fitness level will determine the actual wattage change, it will generally be around 5–20 watts. Adding too much resistance will bring the rider to threshold too soon. Adding too little resistance will extend the overall duration of the PPT Test. Generally speaking, a rider should aim to complete 5-8 2 minute ramps to completion.

The graded ramp process continues until the rider can no longer sustain the workload for an entire two-minute stage. This will be noted by an obvious decline in the ability to sustain steady pedaling, cadence and riding position. The rider’s PPT is the workload sustained during the last fully completed stage.

Below are the guidelines for implementing the PPT Test. This assumes you have your power meter already paired (see above).

  • Tap Indoor Cycling or Bike (outdoors)
  • Tap the Activity Options (Gear Icon located in lower left of the Activity type screen)
  • Tap Assessments
  • Tap PPT Assessment
  • Warm up countdown will begin. Warm-up for 10 minutes at an easy pace, shifting through different resistance loads and incorporating a few 10-20 second hard efforts. Include some transitions in and out of the saddle. You may advance to PST Test at any time during warm-up, by double tapping the countdown bar.
  • After warm up, begin Ramp 1 with light resistance on the flywheel, at a low workload and cadence that feels relaxed and most natural. The app will begin to countdown 2 minutes. During this time, the app will use your current cadence to determine and set a cadence goal for the proceeding ramps.
  • After 2 minutes, app will transition for 15 seconds to Ramp 2. During the 15 second countdown, the app will inform rider of cadence goal to sustain for next ramps. Increase resistance, while keeping target cadence and riding position the same. The added resistance should be enough to feel the change, as if increasing RPE to the next level. This will also be noted as increased wattage. The app will begin to countdown 2 minutes. Maintain the target cadence range, within 5 RPM, while maintaining riding position and resistance. The app will inform the rider if their cadence is higher or lower than the target cadence. After 2 minutes, app will transition for 15 seconds to Ramp 3. During the 15 second countdown, the app will inform rider to increase resistance, while keeping their target cadence and riding position the same. The added resistance should be enough to feel the change, as if increasing RPE to the next level. This will also be noted as increased wattage.
  • The ramp process continues until the rider can no longer sustain the workload for the full 2 minute duration. At this time, rider will slide HEART ICON to stop the PPT Test.
  • The app will display a summary of the PPT Test Ramps. Rider will choose the last fully completed as their PPT.
  • Once the PPT is determined, unique Power Training Zones will be determined based on a percentage of PPT. Power Training Zones allows riders to build their training intensity and boost their current level of conditioning in their current training programs.


Optimize Apple Watch Heart Rate Readings

Ok, so you’ve successfully paired your Apple Watch as a heart rate monitor with Fitdigits. Woohoo! But, then you go to begin a workout and you see something like below… BOO!!!! Read below for info on how to take your heart rate chart to the next level.

If you see something like above, start by checking your Apple Health permissions:

  1. Open the Apple Health app
  2. Tap on Sources
  3. Find your Fitdigits app
  4. Enable all permissions for reading and writing

Try to begin a workout once more and see if this helps.

If you see something like the above, still choppy and all of your Apple Health permissions are enabled:

  1. Close all background apps on the Watch and iPhone
    1. On the Watch, press and hold down the side button until the shutdown screen appears. Release the side button, then press and hold the Digital Crown to force quit the active app
  2. Restart Fitdigits app on Watch and iPhone
  3. Check the positioning of your Apple Watch. The Watch should be snug, but still comfortable. You can move the Watch so it sits higher on your wrist (toward your elbow).

Special notes:

  • Haptics will disrupt the optical heart rate sensor on your Apple Watch. When your Watch buzzes from notifications, it will not query HR for that moment, which can result in a brief dropout.
  • Like with other heart rate monitors, we recommend using one app at a time. Using Fitdigits along with the Heart Rate or Workout app will result in poor readings.

Happy tracking!

Managing Notification Preferences

Fitdigits apps can give you many different types of feedback and encouragement. Of course, not every option or metric is for everyone, so we try to do our best to make the level and types of engagement so there is something for everyone, even if that something is nothing.

Daily Steps & Progress Notifications

Daily Activity Notifications

Fig. 1 – Local Apple Health Notification Options

Local notifications about steps on a daily basis when you are connected to Apple Health or Google Fit. The following options are available:

  • Off (no local notifications)
  • Summary (just a previous days summary each day)
  • All (a few encouraging messages through the day).

Manage these notifications in-app under Partners (Fig. 1), at the bottom of the Platforms section.

Resting Heart Rate Notifications

Local notifications about your resting heart rate on a daily basis when you are connected to Apple Health, which is really based mainly around users with the Apple Watch. Since your Resting Heart Rate is really mostly important when you are starting the day to see how stressed or ready your body may be for exercise, it doesn’t do a Summary option, only an All or Off option. Summary is the equivalent of All.

Manage these notifications in-app under Partners (Fig. 1), at the bottom of the Platforms section.

Heart Rate Zone Change Notifications

Local notifications about when you change heart rate zones during a workout. Since these are very oriented towards the in-app workout experience, you can turn them on or off in your app under Activity Options (gear icon) – select the activity type, tap the gear icon in the lower left, tap on Heart Rate Zones. You will find the preferences at the bottom of the list of heart rate zones associated with your account.

See more on these specific zone notifications.

Goals Notifications

Email and push notifications when goals are reached. Future development to include optional goal progress notifications.

New Personal Records & Bests Notifications

Email and push notifications when new personal bests are reached in a given year. Future development to include optional monthly best notifications.


OS Notification Management | All Notifications On or Off

Whether you are Android or iOS, the devices settings under the App details can be modified in a variety of ways. These will affect both push and local notifications.

iOS (device/iOS level):

Settings > Notifications > iCardio (App Name)


Settings > iCardio (App Name) > Notifications

Please see the following article on what the Notifications options are on an Apple iOS level.

Add Daily Activity & Step Tracking to Fitdigits Apps

Get Your Steps On

Turn your app into a fun, motivating and powerful step and daily activity tracker!

Add Steps to your home screen
We love our partners like Fitbit, Garmin and other daily step and activity trackers, but we do recognize that having to carry or wear another gadget and maintain it can be a bit much, both in terms of cost and learning yet another gadget.

Here’s an easy and effective way to get steps and daily calorie burn just by carrying your iPhone or Android around with you when you move, complimented by more accurate calorie burn when cardio exercises are measured in our heart rate training apps of course! Heart rate is still, by far, is the most accurate personal caloric burn number you can get outside of a clinical test. Accurate numbers mean greater accuracy hitting your goals!

To add steps and other daily activity metrics, simply pair the app with Apple Health (iOS) or Google Fit (Android). Simple! We’ll do the rest, and help you understand yourself better, motivate and hopefully inspire you to greatness! Let’s get our steps on!

Guide on designing fun, effective and interesting interval workouts

The Basics of the Workout Routine Definition

<Routine (for a specific workout type) >
<Interval 1 – do this Z times>
<Series 1>
<Do Pace / Effort Level A for X time / dist.>
</End Series 1>
</End Interval 1>
<Interval 2 – do this Z times>
<Series 1>
<Do Pace / Effort Level B for Y time / dist.>
</End Series 1>
<Series 2>
<Do Pace / Effort Level C for Z time / dist.>
</End Series 2>
</End Interval 1>
<Interval 3 – do this Z times>
<Series 1>
<Do Pace / Effort Level A for X time / dist.>
</End Series 1>
</End Interval 1>
</End Routine>

A Workout Routine is basically an activity you do in a more structured way than what most would call a “free” or “open” run.

There is a point to a workout routine. It can be as simple as completing a set time or distance, to guide you through a recovery run, a steady-state to build stamina, or even a hard HIIT session (High Intensity Interval Training) workout for peak performance and caloric burn.

The basic Workout Routine has the following structure, which is time honored. A routine is broken into time or distance “Intervals”, then from there a “Series” of actions are performed during those Intervals. With Fitdigits, we give you the choice of workouts based on either Heart Rate (BPM), which we call also “effort based”, or by pace zones.

When you are doing custom Workout Routines, it helps to check out the Zone Notifications section so you are prompted to transition when you want.

Some examples of Custom Workout Routines 

Recovery Run 30 min Run: Warm Up, Easy Run, Warm Down
Translates to: Interval 1 (repeat 1 time) – Zone 1 for 5 min. Then Interval 2 (repeat 1 time) Zone 2 for 20 min. Finish with Interval 3 (repeat 1 time) – Zone 1 for 5 min.

Steady State 4 mile Run: Warm Up, Strong Run, Warm Down
(Interval 1 (repeat 1 time) – Zone 1 for .25 miles. Then Interval 2 (repeat 1 time) Zone 3 for 3.5 miles. Finish with Interval 3 (repeat 1 time) – Zone 1 for .25 miles.

Walk / Jog 30 min: Warm up, Jog 1 min, Walk 1 min (do this for 20 min), Warm down. 
(Interval 1 (repeat 1 time) – Walking Pace Zone 5 min. Then Interval 2 (repeat 10 times) – Jogging Pace Zone for 1 minute then Walking Pace Zone for 1 minute. Finish with Interval 3 (repeat 1 time) – Walking Pace Zone 5 min.

Be Colorado. Move. Apple Health Support

Now supports Apple WatchFitdigits is very excited to announce our Apple Watch app release! Heart rate, remote control, data on the wrist for easy access.

Fitdigits & Apple Health

Apple’s Health app is an iOS app that comes standard on the iPhone and iPod Touch. It is a device specific app, it does not share data across devices. You can only be paired with one device and Apple Health at a time. The Health app provides daily steps, active & total calories per day and other metrics that help you gauge your activity levels. The Move app also posts to Health with information about your activities you track with the Move app.


Linking Fitdigits & Apple Health

Pairing the Move App with Apple Health

To link your Move account with Apple Health on your iPhone or iPod Touch:

  1. On the main screen of your Move app, tap Menu > Partners > Apple Health
  2. Tap Enable Sharing
  3. Choose what data you want to send to and from the Health app and Fitdigits (see screenshot). The best thing to chose “Turn All Categories On”.
  4. Tap “Done” in the upper right of the Health app
  5. If you allowed reading daily activity metrics, you will be prompted to sync your data. There are two options:
    1. Starting Today – this will only upload data from the day you tap onwards
    2. All Time – this will sync all days with data on the device. If you previously had data on a date that also has data from this device, it will overwrite the conflicting Apple Health days data from the previous device. If there is no data from the new device, old device data will be maintained (so for most people upgrading, you have a continuous Apple Health data stream).
  6. When the sync is complete, you will be asked if you want motivating messaging through the day, just a daily report of the previous days activity, or no Notifications at all. You can always change this setting by visiting the Partners page.
  7. To view your daily activity, tap Menu > Daily Activity within your Move app.



Apple Health Activity Sharing & Syncing

When you pair with Apple Health, you are initially prompted to sync either “Starting Today” or “All Data”. That is the initial sync for daily activity, and we honor that setting until you Disable the account and re-Enable, which resets the dates.

We do not post past activities to Apple Health, and post activity from our apps at the time the activity is complete.



Daily Activity Notifications


Daily Activity Notifications

One of the first things you may notice, depending on your settings, is the daily activity notifications. We hope you like them and find them motivating. If you would like to modify them, go to the Partners page in the app. Notification settings are below the list of daily activity data providers. The options are –  Off (no local notifications), Summary (just a previous days summary each day), or All (a few encouraging messages through the day).





Background App Refresh

Linked Partner, Background Refresh ONBackground sync of daily activity updates happen if the app is in the background on your device. There is no data transfer if the app has been hard closed and is not available in the app switcher. Background sync is also dependent on having the Background App Refresh permission turned on in the device settings section. You can see what the setting for Background App Refresh is currently for the app by going to >Partners>Apple Health, the screen shows the setting there. To modify the Background App Refresh option for the app, tap  the devices’ Settings>General>Background App Refresh.

You can initiate an update by bringing the app to the foreground after being in the background, or tapping Menu>Sync from your Move app. Please allow a few seconds for the Daily Activity view to update.

If for some reason you need to do a full or partial sync again or for further troubleshooting, you can go to Settings>Synchronization (see Troubleshooting below) for more sync options.



Troubleshooting PairingPreferred Partner

If you are not seeing any data from Apple Health to your Move app, check the >Partners page, make sure Apple Health is set as your preferred daily activity source. We only show and utilize data from one paired source, which can be modified in your Profile section online.

If you are set with Apple Health as a preferred parter, and still having trouble with data flowing one way or another, one of the easiest things to do is go back into the Apple Health partner page within your Move app (see above), tap Disable in the upper right, then tap Enable again to re-enable linking.

One more option is to go to Settings>Synchronization. You can see the date of the last synchronization below the Apple Health entry. If you need to rebuild data, tap Sync Date Reset. The reset should replace the date under Apple Health with either the date you originally specified (if you initially chose “Starting Today”) or say “All Time”. Tap Retry next to Apple Health to initiate sync.

Sync SettingsIf you are getting prompted in the app that there is another device currently linking with Apple Health on your account, but want to change devices, go to the >Partner>Apple Health screen, and tap “Disable” in the top right, which will disable the preferred status of the other device. Tap Enable to enable the current device as your preferred provider.


Modifying Move / Apple Health Share Permissions

  1. Go directly to Apple’s Health app
  2. Tap Sources on the bottom tab menu bar
  3. Scroll down and tap the name of the app (Be Colorado)

You can review or change any read and write settings from there at any time.


What Data Shares with Apple Health?

If you are paired with the Health app using the steps above, after you complete an activity, it will be shared with Apple’s Health app and stored there for review.

Please note the Move app will not send historical data or data pulled from partners (such as steps from Fitbit) to Apple Health, as Apple expressly does not allow it. Apple has advised developers for the Apple Health Kit to not send their data to other activity tracking companies as well.

Also note Apple’s Health data does not sync to multiple devices. So if you have an iPad and iPod Touch, Apple Health will treat this as two separate accounts, leading to possibilities for missed workouts or duplicates (data doesn’t sync to Health across devices).

Fitdigits is excited about the possibilities Apple Health offers, and we will continue to evolve our integration and functionality as Apple does the same.

If you see a difference in Active Calories posted to the Apple Activity app and what is shared to Apple Health, this article on the subject is quite helpful (here).

Fitdigits iOS Beta Program

If you are interested in beta testing some of our newest and greatest stuff, you’ve come to the right place!

Currently Apple Watch stand-alone is its’ own beta and needs a special request for that access – please note that in the request to join the program. The Apple Watch stand-alone enhances our current offering by allowing basic workout and activity tracking to be done using an Apple Watch Series 1 or above. Please note only Apple Watch Series 2 and above will get GPS as well as heart rate when used alone, though if your phone is nearby when doing a stand-alone workout, other versions of the watch can read GPS from the phone in stand-alone mode.

Current Requirements  – Apple Watch Stand-alone:

  1. An Apple Watch Series 1 or above must be paired with your Apple iPhone.
  2. The Apple Watch must be running WatchOS 4.0 or higher. iPhone must be on iOS 10+.
  3. You must have all appropriate permissions (see below for more). Mostly Apple Health Heart Rate permissions (see Partners section).
  4. You must have a Pro Plus level of purchase for the account to use the Apple Watch in Stand-alone mode.

See the bottom of this article for troubleshooting and what to do in case of issues.

Step 1: Request and get an invite

Contact us at support-at-fitdigits.com and let us know you would like to participate as a beta tester. You will need to provide us with the exact email you have associated with iTunes. You can see this email by going to the iPhone/iPad Settings > iTunes & App Stores > Apple ID.

When you are signed up, you will get you are part of the beta, you will get an invite to the Apple beta testing platform Testflight giving you access to the beta version of the app.

Step 2: Download and Install from Testflight

If you are part of the beta, you already have your iTunes associated email in the system, so as soon as Apple approves the beta, it should show up as as an option in the app TestFlight. The new part here, with the Watch extension, is that you must also, after install, switch the switch allowing the program to install to your paired Watch (see the switch in the graphic here >).

Once the watch app is installed, you’ll notice a new option in the Gear / Options menu – Watch Only.

Note on the watch face, in the lower right, there is an indicator that shows either just a watch (stand-alone mode) or the watch and phone icons, meaning it is in “tethered” mode requiring the phone to be near.

To switch back and forth between stand-alone and tethered modes, you can tap on the green icons in the bottom right or tap the gear under the activity icon, and switch on or off the Watch Only mode.

Stand Alone Watch

If you update heart rate zones on the phone, interval / lap settings, or update favorite activity types, you can now tap Sync from the gear area as well, and that will pull the latest info from the phone if the phone is reachable.


In order to run a stand alone workout on the watch, a new permission must be enabled from Apple Health, called Workout Routes. There should be a popup that comes up, please enable there. If for some reason it does not show, open Apple Health and tap Sources, iCardio, and enable the permission there.

Apple Health New PermissionAfter it is enabled, we need to make sure it is registered not just with the phone, but also on the watch. One way to make sure this happens is to put the watch in “tethered” mode, then tap the quick start or the gear icon – you will get a popup if they aren’t communicating, tapping Retry should get the link going if it is available.That’s the best method, if that doesn’t trigger a sync then maybe hard close the app on the watch and re-open.

For more on using the Watch / Advanced Troubleshooting, see:

Using the Watch during Activities / Troubleshooting



Apple Watch Setup & Notes

Fitdigits Apple Watch Apps

See the related post on Apple Health Support

We are very excited to add Apple Watch support to our lineup, including iCardio, iRunner, iBiker, and iWalker.

In the first release we concentrated mostly on functionality and basic activity types – Cardio, Run, Walk, Dog Walk and Bike. You can tap the gear icon on any of them and choose Indoor or Outdoor. The ability to show your favorited activity types will follow shortly, as will metric screen improvements.

The first version offers two modes:

  1. Activity mode: A remote to the phone, you can run, pause, and stop activities, get heart rate from the watch, view in-workout metrics, and more.
  2. Heart Rate Only mode: this will show your current heart rate on the watch, and can be used in our app with the phone to track heart rate within an activity, or simply use it to see your heart rate. Note that a force-touch is required to cancel the HR readings, or, if you do run it with the app in an activity tracked on the phone, ending the activity will end the HR readings. HR takes up a bit of battery, so you probably don’t want it running endlessly in the background.

Current Requirements:

  1. An Apple Watch must be paired with your Apple iPhone.
  2. The Apple Watch must be running WatchOS 3.0 or higher. Phone must be on iOS 10+.
  3. While doing an activity, the iPhone must be in the proximity (bluetooth) with the Watch.
  4. You must have all appropriate permissions (see below for more). Mostly Apple Health Heart Rate permissions (see Partners section).
  5. You must have an upgrade or membership for the account to use Heart Rate from the Watch.

See the bottom of this article for troubleshooting and what to do in case of issues.

Step 1: Download and Install from iTunes

  1. After initial download and logging in to the app, open the Apple Watch app on the phone.
  2. Scroll down until you get to the app you installed listed. Tap on that, then turn on “Show App on Apple Watch”
  3. Make sure, if you are going to use the Watch for Heart Rate, you go into the watch app General and make very sure “Workout Power Saving” mode is not on – that will actually prevent heart rate.

Turn on watch app, turn of workout power saving

Step 2: Login and Enable Permissions

When you first install the app and watch, there are a few things, primarily permissions, that you need to look out for and enable. For people who are just overlaying the install on top of a previous install of the app, these may not be as critical, and you can skip to #3 below.

  1. On a fresh install, two permissions come up for Location and Notifications, tap Allow to allow them. You may also want to run an initial workout, and in the workout, tap the gear icon, then tap the camera, allow that permission, take a picture, then allow that permission as well. Just to get them all out of the way :).
  2. Login to your account, allow the app to sync through at least a few workouts to make sure all your account information has come down.
  3. Go to Partners > Apple Health – at a minimum for heart rate, enable Heart Rate permissions
  4. Go to Menu > Sensors, turn on the Apple Watch HRM to use the Watch as a Heart Rate Monitor. Turn off any other heart rate monitors you may have paired.

Step 3: Using the Watch during Activities

Issue: If you are using the phone as a base to start / stop etc, sometimes it will “save” the last BPM on the phone, and when a workout is started, it thinks it has the Watch since it has a bpm, but then it just never gets the updated readings / never actually launches on the watch again. If you hard close the app, that will clear that value, in which case starting from the phone will simply time out trying to get the heart rate.

When using the watch, it is best to either use the watch as the primary interface, or, hit the Gear icon on any type and pick the HRM Only option in that screen before using the phone to start the workout. Kind of like other heart rate monitors, it has to be functioning to get it to read correctly.

Using the Watch during Activities – Tips for a Better Experience

Tip 1: Tighten the Watch while Tracking Heart Rate

Please note that, like most wrist based HRMs, the values are not quite as accurate as those of chest straps or the Scosche Rhythm+. It helps to tighten the watch on the wrist area a little more while tracking HR, and also even to slide it down the forearm a bit farther from the wrist.

Tip 2: Extend the time the screen shows

For us, we found changing the settings on the watch from a 15 second time-out for the display to a 70 second time-out for the display made for a much better watch experience. You can do this in the Apple’s Watch app, under Settings > General.

Apple Watch General Settings


Tip 3: See the following Watch Optimization article



Apple Watch Connection Error

  1. The number one way to get a non-responsive watch instance back in line with the phone app is to open the phone app, start an activity then (even before full launch) cancel that activity. That has been shown to get things back communicating and initialized after loss of connection. We are working on better handling in this instance.
  2. Sometimes the connection mentioned above can be re-established by pinging the phone from the watch. You do that by having the home screen on the watch (not the main apps, but the main watch face) and swiping up from the bottom bezel to get the Watch equivalent of the phone controls. Then the Ping phone is the lower left button with the phone icon. Tap that and it will ping on the phone (a good way to find your phone too).
  3. If a workout is running – you can hear it in the background on your phone, but you don’t see it when you open the app, and #1 above doesn’t work, you may need to hard close the app on the phone.
  4. If the watch app gets in a state that might not be responding and you don’t see any buttons to press, you can try a full bezel swipe from left to right to go back a screen (swipe from the very edge of the bezel to the other side of the bezel on the watch). If that doesn’t help, you can hard close the watch app by following these steps:
    1. Make sure the app you want to hard close is the one running in the foreground.
    2. Push and hold the bottom button on the right of the watch until the power off screen appears.
    3. Push and hold the digital crown button. You will see it go back to the main apps screen, that hard closes the watch app.
  5. If no heart rate, see the installation note on making sure, in the Watch app, that in General settings, Workout Power Saving is OFF. If it is ON it won’t allow heart rate. We have seen where an update from Apple has switched this to on without anyone touching it themselves.
  6. If you ever need to re-install the iCardio Watch app, go into the Watch app on your phone. Tap on iCardio in the apps section on the My Watch tap. Turn the Show on Apple Watch switch to off, it will uninstall (wait…). Once uninstalled, tap it on to install it again.

Installing, or re-installing, the Apple Watch extension


In-Workout Options – iCardio, iRunner and iBiker

So you are in the middle of your run / ride / yoga session, and you decide you just want to have quiet for a change, or perhaps you just want to put your phone down and have it auto-swipe through all the dashboard screens. Maybe there is even something else you want, like changing the background from one friendly to bright days to one more appropriate for night or the gym.

We have the solution for you – In-Workout Options, configurable on the fly.


Access the In-Workout options by tapping the gear icon while the workout is running.

In-workout options selector

From there you will see a variety of options available that can change your experience on the fly!

In-workout options iOS

Lap: This will mark a Lap. See also Working with Laps and Splits.

Camera: Take a picture and have it associated with the current workout.
