For some reason, Google decided it was a good idea to replace the feature in Google Fit on WearOS watches that detects which lift and how many sets/reps you’re doing with a glorified stopwatch. Here’s how to get the old version back:

1. Enable debugging and adb connect to your watch
2. Run adb uninstall com.google.android.apps.fitness. This erases your data, but it should still be there stored on the cloud under your Google account so NBD. Unfortunately Android 7+ doesn’t let you downgrade non-debuggable apps while keeping data due to security risks.
3. Download the latest version of Google Fit for WearOS that still has this feature (2.44.14).
4. Install it: adb install com.google.android.apps.fitness_2.44.14-230-2024414230_minAPI25(nodpi)_apkmirror.com.apk

I would recommend disabling debugging after because sometimes my watch stays connected to wifi for no reason and drains battery when it’s on.

Hope that helps. Make sure to ask Google to bring this feature back (instructions here). Now if only I lived in a state where people at the gym can actually care there’s a global pandemic going on…
