3 stars: It does work, but has several problems. Like various fonts are too small to read. A major problem is massive battery drain, at least on my MotoG. Even if you 'disconnect band' and turn off bluetooth, it's still running with high battery use. Only Force Stop will end it. That's nonsense - fix please.
3 stars: Update: Downgraded (a term unknown to google or Samsung brainless devs) to version 2.7.3 and now it stays connected. However, sleep data is not working at all. ------ Constantly disconnecting and will not reconnect by itself. Most times I have to restart the phone to establish connection back.
3 stars: I was told it could sync to my GMail and notify me of emails as well on the wrist device, but I can't find any feature for that kind of notification
4 stars: Good app would recommand but sometimes hard to read sleep time ,step time on app but good app losing time on watch about min aday so....keep app connected for time to be right and sd card moved would be nice
3 stars: feedback section do not send the massages and stocks. Alarm adjustment is not available directly from the phone and it must open the app to adjust alarms. just 2 them clock screen.
3 stars: Needs the 2020 bug fixed. Hourly readings haven't shown up since late Dec 31st.
