1. You've already paid good money for a smart watch, what's a few dollars more for great tracking software? It has just what I need for my Mi Band 2 and nothing more! The English localisation is clumsy in places, but that's not going to stop me giving stars.Good app, I use it to sync periodic heart rate readings from my Mi Band 4 (and Mi Band 2 before that) to Google Fit.

2. My second waking period at 355 ish I was actually using my phone and walking around and the app seemed to think I was still asleep! Then when it realised i was awake, when I returned to sleep until 8 ish it didn't even detect this phase of sleep and currently shows I woke up at 4 am ish.

3. HR monitoring works fine, it's the first app I discovered that doesn't require a standing Bluetooth connection in order to do a HR reading every 2 minutes! Thanks for that, good work.

4. I bought the app primarily for sleep tracking, and whilst it seems to play okay with sleep as Android, it doesn't track my waking periods in the night accurately.

5. Everything's good, but it feels like the work with notifications is not completed: there is no option to work with one single app, and you can't get application title in notifications.

6. I'd like to be able to only sync heart rate data and nothing else.Almost perfect! However, some things I wish the app could do is firstly, for it to communicate with my Mi Scale 2.

7. Not sure why it didn't work, looks like a good app, but it caused more problems that I thought it would.The one star was just to get your attention.

8. Second: I wasn't able to find anywhere if this app shows the content of your message in the band notifications, like mi fit does.

9. Btw I was using it with mifit which shows the waking periods okay - unless they're after 545 am, which is why I was recommended your app as a superior option! Otherwise, an interesting app.

10. Having opened the Mi Fit app, that started to get stuck and was soon struggling to connect to the band.

11. For example, last night it detected my first waking period of 40 mins.
