OtterBreath is a free breathing app with 6 guided techniques — Box Breathing, 4-7-8, Extended Exhale, and Conscious CO2 — plus a custom exercise builder if you want your own timing. Calming background audio, a simple session history, and zero accounts or ads. Built it solo as my first app to help with my own stress and sleep.
Hey everyone 👋 Maker here.
I built OtterBreath because I wanted a breathing app that didn't
need an account, didn't have ads, and let me actually name the
technique I was doing (box breathing, 4-7-8, etc.) instead of just
"breathe in / breathe out."
It's my first app ever — built it in React Native with a lot of
trial and error. Would love any feedback, especially on the session
screen and whether the timing/pacing feels right.
Free on Google Play, no login needed. Thanks for checking it out!
