If you see the wrong language for our app in Apple Watch, there is the easiest solution to solve it and to switch the Watch app to English:

  1. Delete our app (from your phone) and reset the watch. (NOTE: Check that you logged in because you need to use the same login credentials.)
  2. When installing the watch choose English as language and your native language as a region.
  3. Re-install watch from a backup.
  4. Install App in the Air. It now works in English on the watch!
  5. Change language on the watch to the native language. Our app remains in English.
