This is a fantastic app. It's very easy to use and offers an awesome variety of exercises from simple apnea tables to guided breathing exercises. Could not recommend it more. It's visually stunning, bug free, and you can tell the person who created it actually uses these exercises. Thanks for putting such a great product out!

Very nice and clean app with surprisingly fun apnea excersises. Definitely recommended for free divers and breath work enthusiasts!

I've been wanting to start apnea training but was hesitant since I would be doing it alone. This app and the ntx approach had changed that. I'm just a week in and have had amazing progress without any danger of passing out. Highly Recommend!

I'm very impressed with this high quality breathing and apnea training app. The instructions and exercises are easy to follow. If you've tried static O2 and CO2 tables before then these exercises might seem strange at first, but after giving them a few tries the structure and philosophy behind them will begin to make a lot of sense. Thanks for making this app available for free!
