very good

With version 1.46.0 I can't use the app for more than 2 months. I have to uninstall and re-install but after a while, it stops working. The sync process doesn't work every time, sometimes only when I access the app.

I regret buying this watch. The app is not useful at all. The watch does not connect to the app. Watch battery died and lost time. To reset time I have to connect to the app, but since I cannot connect this means the watch is completely not usable. Also the watch has a tendency to switch off whilst I am running. I can stop at 1 or 2km, making it very irritating to use it for running.

Bassically i have a CW500 device that often stops connecting to the app. Every time it does this i have to reinstall the app which is SO annoying. Other than that it's really good, it keeps track of everything. But yeah there's that bug.

Could be better

Auto direct app when I login or registration or anything this app is suks , disgusting experience, I believe this company before now I'm regret after buying decathlon smart watch because first time connect to app but now different country app stop working .

At some point the apps stops synching - especially if the watch battery is exhausted completely. I needed to de-install the app from my mobile (Android based) and then install it again to get it synching.

Very good

Disconnects from the watch several times a day and never reconnects. I have to reset the watch every time losing my progress for that day. Pretty useless. I'll save up for a garmin next time

The app doesn't work, I've installed it on different phones, the app is not able to pass from the splash screen
