User reviews

awesome!! daily user for 3+ years

really love the app, been using it for maybe 3 years for probably all my slumber. this was the solution to all my problems. other alarms make me literally jolt out of bed but this app subtly wakes me.

although occasionally (maybe 4 times from all the times ive used it) i cannot hear it go off. a few times i was awake elsewhere and the alarm would show the snooze button without sound. however, i cant tell if its due to the app or because i have an iphone

Best alarm and sleep tracker!

Been using for decades now- and still works wonders

Classy

Really good

Cannot Restore Premium Features Anymore

The fact that I had to click through the Try It Free button every day just to enable the features I had paid for years ago was bad enough, now they won’t even let me use those features anymore!

What a world we live in where the software you paid for can be disabled remotely one day!

Ridiculous - No edit feature

I forgot to swipe when I got up, so it counted the next two hours as sleep time when I wasn’t even in the room. No way to fix it.
