1. Most of the notifications are hard to read and it often only partially shows the message, which makes it pointless.Most of the times my watch got disconnected from my phone even though the Bluetooth is on and both devices are within range.

2. 😔 Also, it would be very helpful if WhatsApp business is listed in the msg notifications.1. The app and the watch keeps getting disconnected once the app is closed on the phone.

3. Not only that, even if the setup is done, the reverse works like time change, it works automatically even after making the heart rate manual, but it is still seen that the apps are done manually.

4. Very painful.The app seems to work fine on the health side, but the options for notifications on the watch are very limited and are quite poor.

5. I have swiched to use Haylou Fit, and works better than this one, at least doesn't keep disconecting all the time.Application does not run on background even if the permission is already allowed.

6. I got the watch for the only purpose of measuring my continuous heart rate during exercise so I can stay in the zone but it showed only 130 to 140 bpm whereas my heart crossed above 200 bpm.

7. *A firmware update on the watch would be great for a better and smoother ui experience.The app fails several times, keeps disconecting from the watch.

8. it doesn't display the workouts on the watch wether the LS01 does.

9. Adding way to edit/download watch faces would be a great feature too.Highly disappointed.

10. The only use left is just a smart watch and it comes with a very bad user interface App.

11. First of all the watch LS02.
