My main use for the app, and for my CMF Watch is to control music while my phone is in my pocket. The issue I have is that the volume slider of the watch itself closes once the screen turns off, and I have to tap that tiny button to bring it back up, and THEN use the dial on the side to turn up the volume! If we could get a revision of the music area and gain the ability to more smoothly control audio with the dial while awake, I'd set the knob to do volume control at all times if I was able!

Unfortunately, I was prompted to switch from the CMF Watch app to this app for tracking activity. After the first day of switching, my battery SIGNIFICANTLY drained. I checked and found that this app showed 11% usage in the mort recent block. The next highest was 3%. When I checked the usage levels of the cmf app, it was never even over 3%. If you're going to force us to move to a different app, please fix the battery drain issue because I cannot continue to use this app.

WHY can't I edit indoor bike distance like I can with indoor run distance??? I feel like this should be a pretty easy thing to do? how am I supposed to improve when the app isn't gonna properly track it? devs might say - "we don't track that", well, Google fit thinks ya do, and I can't change it there. so I look like a wimp. just let me edit the log! thanks!
