Fitness App Not Working on iPhone 13 or iOS 15: How to Fix

Apple Watch has been a much-welcomed addition to the lives of iOS users. You not only get another nifty device on your wrist to keep in touch with your phone, but you also get access to various health and fitness features to help you be the best version of yourself. You can track your heart rate, sleep, steps, and more.

Apple even has a dedicated ‘Fitness’ app for the same but the recent release of iOS 15 seems to be causing issues for many users. Additionally, users with the latest iPhone 13s are also having trouble syncing their Fitness data between their Watch and phone. If you’re in the same boat, then use the fixes below to solve your issue.

How to solve Fitness app problems on iPhone 13 or any iOS 15 device

The Fitness app seems to have issues with every new version of iOS, especially for new devices. This could be an underlying problem with Apple’s syncing services or iCloud servers themselves. Either way, most users end up fixing their issues by rebooting their Apple Watch.

However, if that does not work, you can opt for the other known fixes mentioned below. In case you are facing the rare scenario where the Fitness app still fails to work or sync for you then you can perform a few checks and try the general fixes mentioned below. Follow the guides to get you started.

4 checks to perform before trying any fixes:

If you are still unable to use the Fitness app then we recommend you perform the following checks to ensure everything is set up properly on your device. If anything was wrongly configured, you can fix it and then try using the Fitness app again. If a mismatched setting is the cause of your issue then these checks will help you fix it.

Check #1. Ensure tracking has been enabled

The first thing you should check is permissions for your Watch and device to access your fitness and health data. You can use the guides below to check if the necessary permissions are enabled on your device.

On Watch:

Open the Watch app and tap on ‘My Watch’ at the bottom. Tap on ‘Privacy’ in the list at the top and enable the following toggles.

Heart Rate
Fitness Tracking

On iPhone:

Open the Settings app, tap on ‘Privacy’ and then select ‘Motion & Fitness’. Now enable the following toggles on your device.

Fitness Tracking
Health

If either of the above-mentioned toggles was disabled for you then it is likely the cause of your workout sync issues. You can now try to sync your Fitness data again and it should now be working as intended.

Check #2. Ensure that you are running the latest update

Apple releases hotfixes and patches in the background regularly. Apps are also updated to ensure compatibility with these updates hence we now recommend you ensure that you are running the latest version of iOS 15 on your device as well as the following apps.

My Watch app
Fitness App
Health App

You can check for pending iOS updates by going to Settings > General > Software Update.

Check #3. Turn off Low Power mode

We recommend you turn off Low Power Mode on your device for maximum connectivity and to ensure that your device has permission to sync without worrying about power consumption.

While Low Power mode rarely causes issues with the Fitness app, you could be facing a background conflict with your previous cache or data which could be causing this issue. We recommend you try to sync your workout data with Low Power Mode disabled on your device.

Check #4. Check your network connection

Lastly, we recommend you check your network connection. If you are facing bandwidth or network issues, then it is likely the reason for issues with your Fitness app. We recommend you connect your device and watch to a working WIFI network and leave them plugged into the wall for a while.

This will allow your devices to use sync and background services to sync your workout data in an idle state. If a network issue was the cause of your problems, then you should now have all your workout data synced across both devices.

7 Fixes for Fitness app issues: Workout data not being recorded, app not working, watch data not syncing, and more

The most common issue for users that have recently updated to iOS 15 or are using iPhone 13s seems to be missing workout data or data from the watch not syncing to their iOS or iPadOS device. We recommend you start with the known fixes and follow the order for each method. It is crucial that you reboot and pair at the correct time during these guides and do not skip them to maximize your chances of solving the issue.

We are covering below various fixes for the Fitness app but starting the basic ones first.

Fix #1. Re-launch the Fitness app

We recommend you force close Fitness from the multitasking menu and then leave your device idle for a while. You can then try opening and using the app again. A fresh start will help reestablish a link with your Watch which should help record and sync your workout data easily.

Fix #2. Toggle Airplane Mode

You could also be facing network issues on your iOS device which could be the reason for issues with your Fitness app. In such cases, you can turn on Airplane mode, wait a few minutes and turn it off again.

Your Bluetooth will also be restarted which is what is used to pair with your Apple Watch. A refresh of all your connections should help solve sync and workout recording issues with the Fitness app.
