So far not really enjoying it since it keeps changing the ringtone of the alarm I wanted back to the (default) "Radar" which makes me frustrated. Can you guys also add the apple's "Radial" alarm ringtone to this app and I find the "BTS ringtones" quite disturbing can you guys remove it?

Surprisedly no ads (so far). Nice UI to almost the same as iOS. In stopwatch it's using comma instead of dot. No settings available for users (personally, I don't mind it at all) , but it has alarm sound setting options. So far so good. Highly recommended. I will update my comments if I experienced something else later on.

It needs to be updated also the font needs to be bold I love that there are no ads in the middle (because that's an immediate dealbreaker)
