### 1/5 — Don’t bother

*2026-05-11*

This is a terrible app. It is stupid. I can’t believe I spent money on it. It doesn’t even track properly to Apple health. There are zero options.

### 1/5 — CRASHES  adding bedtime

*2022-01-25*

Adding my first entry, it prompts me to enter what time I went to bed and when I hit enter it CRASHED.  Tried it 6 months ago and retried today.  Total crap.  It’s only supposed to do a couple of basic things and it can’t even do that!

**Developer response:** Hey there, thanks for taking the time to try out zZz! May I ask what exactly happened? I am using the app myself and it works just fine. Did you give health permissions? At which times did you go to bed/wake up at? Please feel free to get in contact via Twitter @FloWritesCode. Thanks!

### 2/5 — can’t delete data

*2023-05-08*

Good idea for tracking sleep.
However you can’t delete entries.
Which means if you made a  bad entry, too bad.
