This app just keeps getting better! The new updates are so helpful and I’ve found it so easy to use. Best breath app around. Premium features are worth it too!

### 5/5 — Love the tool, bug still there

Using it for CO2 training. Finally worked out why my cardio is so “bad”. However the timer in the CO2 tables jumps from 2 minutes to 22 seconds and then keeps going down.

Helped to increase my max breath hold and overall stress tolerance.

Beyond the physical benefits, the app has been instrumental in focusing on controlled breathing  and mindfulness exercise

### 5/5 — Incredible tool

I have been using this technology for years, but I never thought an app could make it so easy to track and monitor. I have increased my lung capacity over 30% since using this. Highly recommend!
