If Hevy is not syncing correctly between your iPhone and Apple Watch, follow the steps below. Start with the connection checks before moving on to restarting or reinstalling.
Before You Troubleshoot
Syncing can occasionally be delayed or temporarily interrupted, even when the connection generally works. Information does not always appear on both devices immediately, as some communication between Apple Watch and iPhone apps happens in the background.
If you notice a delay, open Hevy on both devices and check whether the information catches up. Before continuing, confirm that your logged sets are showing correctly.
Repeated freezing, missing workout data, or being unable to save a workout should not be treated as a normal delay. Follow the troubleshooting steps below if the issue does not resolve or keeps interrupting your workout.
1. Check Your Device Connection
Start with these checks:
- Keep your iPhone and Apple Watch close together.
- Make sure Bluetooth and Wi-Fi are enabled, and Airplane Mode is off.
- Open Control Center on your Apple Watch and check its connection to your iPhone.
A red iPhone icon indicates that your watch is disconnected. A green iPhone icon indicates that it is connected.
2. Open Hevy on Both Devices
Open Hevy on your iPhone and Apple Watch. Keep the watch app visible and hold your wrist up for a few seconds, then check whether the information updates.
Before starting a Hevy workout, check that another watch app is not still tracking an active workout. Hevy’s troubleshooting guidance recommends closing other workout-tracking or live-syncing apps before trying again.
3. Close the Apps and Restart Your Devices
If the connection checks do not help, try the following when you are no longer recording a workout:
- Close and reopen Hevy on your iPhone and Apple Watch.
- Check whether syncing resumes.
- If the issue continues, restart both devices, then open Hevy again.
Restarting is a troubleshooting step, not a guarantee that the issue will be permanently resolved.
4. Check for Updates
Check for available updates to Hevy, iOS, and watchOS. App and system updates can include fixes for unexpected behaviour. Use the newest software version supported by your devices.
To check for a watchOS update from your iPhone:
Watch app > My Watch > General > Software Update.
5. Reinstall Hevy as a Last Step
Only try reinstalling if the earlier checks have not helped.
Before deleting Hevy, make sure your recent workouts have synced to your account and that you know your login details. Deleting an app can remove data stored locally. If a workout has not synced or you are trying to recover missing data, skip this step and use the support section below.
To reinstall:
- Log out of Hevy.
- Delete Hevy from your iPhone and Apple Watch.
- Restart both devices.
- Reinstall Hevy on both devices and sign back into the same account.
- Open Hevy on both devices and check the connection again.
What If the Problem Comes Back?
A temporary improvement does not necessarily mean the underlying issue has been resolved.
If the same problem returns, note when it happens and how often, rather than repeatedly reinstalling. For example, does the watch stop responding after a rest timer, when you log a set, or when you try to finish the workout?
Some issues may require further investigation or a Hevy app update rather than additional changes to your settings.
