### 1/5 — looks nice but not functional

*2025-03-10*

i have this and the “sleep time” app downloaded. i want this to be able to be my main sleep calculator app because it’s cute, but it is very lacking. i wish this app had a nap length of sleep plus 1-7 cycles, and that it told you the total time you will be asleep. if it had all of the information that “sleep time” does, but kept the same look it currently has, it would be my main sleep calculator app.

### 2/5 — Seems Nice

*2024-01-05*

The first 2 sections are good, but the guide crashes the app. Took off some more stars since every link goes to a dead site and there’s no way to contact the developer. Would like to use the app to its full extent, hopefully it gets updated.
