Circadian Rhythm Needed

Because the minimalist design alarm did not work. For some reason it worked yesterday afternoon. No explanation for multiple notifications that can’t be accessed in any way I could figure out. Most reviews are years old. Maybe too minimalist.

Getting better

I love the simple design and ease of setting.
It’s just an alarm. Period. Hard to screw up. The devotees still need to work on iPad compatibility and when a decide rotates the screen is really messed up. Let’s get these bugs worked out!
