Can't speak for exercise tracking, but for tracking sleep, this app with a Gen 2 ring are simply SUPERB. Been using it for months, and it has been DEPENDABLE. Even more to the point, the data has been reasonable and very useful, even agreeing with medical monitorings. Activating the sleep monitoring mode could certainly be quicker! But the data transfer rate is fabulous compared to other devices I've used. I've made a couple suggestions for improvements & my feedback was treated with respect.

Apparently one or more recent updates broke something. App can get real-time info after a bit, but sync to download sleep tracking never completes. Sync progress is very slow, and app keeps crashing before in completes. No full sync in a week. Open the app and it goes right back to a very slow download. Release notes say bug fix. Apparently, my obscure Samsung Galaxy S22 Ultra isn't a device worth regression testing for the "bug fix" in the release notes. Just ordered a Samsung Ring.

a few features needed 1. See steps for the whole day, include steps from other devices if the ring isn't worn 2. a widget to show key data and start an exercise 3. when listen to audible and voice guidance comes on the audio is stopped not paused. 4. Distance walked is very inaccurate, it is too high than my samsung watch 5.a way to reboot the ring, mine crashed for half a day. 6. Bedtime time is too late by at least 30 minutes, ask when I want to get up
