Already making impact
This app is great, the categories are very helpful and the game is great too.
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.
Best free app out there
Helped to increase my max breath hold and overall stress tolerance.
Great app!
Beyond the physical benefits, the app has been instrumental in focusing on controlled breathing and mindfulness exercise
Works Great!!!
Love this app, helped so much with my breath hold and overall fitness, can’t recommended enough!
