5 stars: Back online, working perfectly so I revised it to 5 stars. It has Beidou, the rests are obsolete now.
5 stars: I've been using this app for a couple years (formerly amazfit, now Zepp). It's had some quirks and issues. I've sent at least 3 bug and feature requests and they have all been addressed! I use the app with a Stratos 3 watch and sleep buds.
3 stars: Update 12/25/20 Remove 2 star, sleep tracking is inconsistent, sometimes it does not capture a full night. Also selection of sounds is not great, need more as I only use the ocean waves as the rest of them are poor choices. Great It, it works good for my Zenbuds. The Sleep data is well laid out and easy to understand. Please add more sounds, especially a crackling fire/campfire.
3 stars: There seem to be a number of simple things they could do that would make this a lot better. Daily calories burned, for example. It would be nice to be able to zoom in. The PAI counter is simply wrong much of the time (i.e. it doesn't actually add up the last 7 days). The watch works well though.
5 stars: I use the 3rd generation Stratos watch with the app although I had a Pace watch before and was just as satisfied. Love the sleep tracking and for recording exercise it is great. I particularly like the Total Effort score that it generates. It works seamlessly with Strava as well.
4 stars: There was an issue with high intensity heart rate tracking. It seems to have corrected. I'm not sure how it syncs with googl...
