5 stars: Its work very well with my VIVO Y21. There should be notifications for other apps apart from the social media apps installed on this app. Also, it doesn't show number of time you wake up.
5 stars: This app does not work at all since the update! When you start it up it closes right away on my android phone. It was working well before.
4 stars: PROS - It does what it says it does :) - The application actually looks nice and is easy to use; CONS - I sometimes have to restart my phone in order for the stats to update; - Sleep schedule is not adjustable to my own so the stats are always false since I wakeup pass the limit time; *** - I would like to be able to track more things like body measurements (not just weight and height);
4 stars: I'm giving this 4 stars because I know it has room for improvement. I love the long battery life. My only problem is how it synchronizes with Goggle fit. Its not constant--some days it tracks my heart rate but does not sync my steps done in the whole day. Sometimes it does not sync my activities and I need to manually enter them into my Google fit. I hope you can fix the sync feature!
2 stars: I've had the watch for awhile and as soon as I charge it up it doesn't work. I have to unbind and sometimes the blue tooth doesn't find it and even when it does that makes no difference. I get it working then a few days later have to start the whole process again! It would be great if at least the watch showed the right time. As soo...
