### 5/5 — the best sleep and relaxation apps I’ve used — easy 5 stars

*2026-05-08*

I’ve tried a lot of sleep apps, but this one feels genuinely thoughtful.
The sleep cycle planner helps me choose the best time to sleep or wake up based on natural 90-minute cycles, and I wake up feeling much less groggy.

**Developer response:** Thank you so much for the thoughtful feedback!
