Troubleshooting Issues with Apple Watch / Live Sync

Issues and stability problems with Apple Watch can be caused by multiple reasons, which can be difficult to track down.

We recommend the following guidelines:

Please try restarting your Apple Watch and iPhone

  • If this is the first time you have experienced issues, please try restarting your devices. Also ensure you are on the latest version of Strong, iOS and watchOS (see below).

Please use the latest versions of iOS, watchOS and Strong

  • Please make sure you are on the latest version of iOS, watchOS and Strong that are available to you before contacting us. There may be issues with Apple's own watch connectivity APIs which may affect performance. In any case, due to the rapidly changing nature of watchOS development, we rely on users being on the latest version of watchOS.
  • Unfortunately beta releases of iOS and watchOS can cause issues with watch connectivity, with watchOS in particular. Please note we are unable to offer dedicated support if you are on beta releases of iOS or watchOS.

Please use the best hardware you have available

  • Strong for Apple Watch will perform best on Apple Watch Series 3, 4, 5, 6, and SE (the newer the better). 
  • An iPhone running the latest version of iOS (iPhone 6s or later) will be required.
  • Earlier Apple Watches are significantly constrained in terms of system resources and this will impact the performance of both sync and general use of the watch app. 
  • If you are using an older Apple Watch model (Series 0, 1 and 2), we do not recommend using Strong for Apple Watch and we do not plan to support these models in future updates of Strong.

Limit use of other watchOS apps, especially if you are on an older Apple Watch model

  • Strong for Apple Watch should be prioritised by the system while in workout mode, but please try to keep use of other apps to a minimum, especially those that are more resource intensive. Those can be run on iPhone if necessary.
  • We do not support the use of other workout apps such as the native Workouts app at the same time as running Strong with Live Sync.

Grant Apple Health Permissions to Strong

  • Please make sure that Apple Health permissions have been granted to Strong (Workouts in particular), as this will allocate more system resources to the Apple Watch app.

Please work out with the best network connection possible

  • Please make sure a high quality Wifi AND Cellular connection are available to your Apple Watch.If your gym or workout location does not have access to either of these, sync performance may be compromised.
  • If the wifi or cellular connection are poor and/or sporadic, this will further affect the watch's ability to send data and will significantly affect sync stability. We understand you may not be able to control the network at your training location and in those situations, no connection will be better than a poor connection, so experiment with turning WiFi off if that applies to you.
  • Please make sure you are not running on a public or restricted wifi or using a VPN.
  • If you experiencing connectivity issues with Strong during a workout, please attempt to reproduce issues in an environment with both high quality WiFi and Cellular access to help pinpoint if this is the issue.

We're aware that some users are facing issues and are working towards long term architectural improvements on the Apple Watch app which should improve stability for all users.
