Absolutely love this app. Found it through a google search. Thank you for developing it!

### 5/5 — Man what a difference

*2026-06-26*

This has really helped my sleep habits. Granted, I still stay up way too late, but I’m easily able to calculate out when is best to set my alarm. It’s been spot on every time and I wake up feeling rested, even if it’s only been 3 sleep cycles. It feels like magic lol

### 5/5 — Literally my favorite

*2025-09-21*

I was using the website before the app came out and I was already in love with the way it functioned. The beta testing was so smooth and I’m so excited they finally released this app! 

Being able to mix and adjust the different nature, and static sounds and save them is my favorite. The calculator itself works like a dream (no pun intended) but they really put love into this app. Also THANK YOU for the dark mode and different app icons! Kudos to the developers! 🔥💯
