I like this watch a lot. I can track my heart rate, sleep, pulse ox, and stress levels. I can set up to 8 alarms, make and receive calls, and receive texts and other notifications. I can do all kinds of workouts from the app. I can even personalize the face! One feature I wish it had was to tell the battery level while charging.

Limited App Sharing. I got this watch and app when my Samsung watch broke, and I'm not able to get a new $200+ watch at the moment to track my sleep. the watch seems to track sleep cycles well enough, but I can't figure out how to transfer the sleep info to my main fitness apps. I've been trying all day, and can't get anything beyond weight and steps to connect to my other apps. Cheap materials & interface. It's disappointing, and the main reason I got this watch, so I'm going to return it.

It works with my calls, messages. Heart rate, blood oxygen, stress only work when you actually hit measure. Sleep does not work well at all. I cannot figure out how to fix the sleep monitoring from having me fall asleep almost every day exactly at midnight, when I have been in bed sometime 2-3 hours prior and am sure I have fallen asleep. I even wore my Fitbit and this watch one night and my sleep was 3 hours different. Can't find anywhere on how to fix. Wouldn't recommend for sleep tracking.
