The app used to work very well on my Ticwatch Pro 5 (WearOS 4), but the developer decided to drop support for WearOS versions earlier than 6, so now it doesn't work anymore. The app still can be installed but crashes upon launch and the watch face shows a "missing app" notification. Please keep a legacy version for WearOS 4!!! I'll update the rating to 5 stars once this is fixed! Thank you!
