We learned that runners that run with the Apple Watch and the iPhone at the same time can run into a few issues. This is caused by iOS, not by the Stryd app.

- Apple Watch can momentarily disconnect from Stryd

- The GPS map might have incorrect data

You can avoid these issues by disabling Bluetooth on the phone or leaving your phone at home. This is not ideal for Stryders that use Bluetooth headphones with their phone and therefore the development team is aware of this problem and will try to address this problem in a future release.

You may want to consider the iSmoothRun app for iPhone and Apple Watch as it has a special mode for runners that have to carry their iPhone with them while running with the Apple Watch and Stryd.
