Great for tracking fitness and sleep, would be nice if it linked with more apps, such as Google Fit. Standard EU/UK time format (DD/MM) would be great on the GBD H-2000 as well (It's confusing seeing the month before the day for some people, myself included). However, solid functionality and ecosystem across the app and the wrist unit. Great for keeping track of my sleep and activity. I've walked around enough to have collected every badge, too. Do I win a prize?

So far i have found the app to be working well it was easier to set alarms on the app rather than on the GWG-B100TLC small buttons are a pain for numb fingers. The auto synch has performed faultlessly ( so far ), but i have noticed that the recharable battery never seems to read more than medium even after leaving the watch out in brilliant sunshine all day. Because it wont go to high level it wont beep on the hour and the alarms wont sound, so i still use alexa alarm.

The app doesn't work. I tried to change the analogue hands using the app to correct it, and every time I do, my watch just puts in some random time that does not correlate to the hand position on the app. Now, while the digital part of the watch is correct but difficult to read, the analogue is constantly incorrect, synced by Bluetooth, but still does not correct the hands to the correct time. ...Isn't telling the time the very basic function of a watch, Casio???
