Apnea Trainer

This app comes recommended by Tim Ferriss. I’ve been trying it for just 5-minutes every morning, which is really grounding. It’s a elegant way to improve your overall breathing incrementally with time. Plus, love the gong sound at the end. Great job developers! Tip: Enable “Voice Count Down”!

I've tried a few apps to help my spearfishing time underwater the breath up is definitely the most important part I learnt it primarily from this app! How long you should breath in, breath out, also how long to pause. I've never reviewed an app but this one has blown me away with the instantaneous results. Thanks chaps

Only just started Apnea training and didn't have a clue. This does all the guess work for you. This is not a gimmick. At the present time this is the only training I do and I have gone from just over a minute to 3.02 minutes static breath hold. Definately give it a go.

It's very nice app, helps a lot, all answers are in FAQ and help. Some improvements would be nice... 5*

This app is amazing for training, improving, helping and getting you ready for any dives. I have used this app for about one mouth, and already improving rapidly. I use it twice a day every couple of days I am making it harder for myself. I highly recommend this app.

No clear explanation of the program and what you are supposed to be doing, when, for how long, how the program progresses, left pretty much in the dark. Unmotivated to carry on currently. I am sure if you know the basis behind it then it would be fine, but if you are expecting this app to explain the program and the methods....it doesn't in an way.

Useful app if you want to improve or start getting ready for the summer freediving season. Could not find out how to reset and take again my parameters!

One of the best apps around for anyone looking to increase capacity.

Already noticed an improvement in my downtime.

This app is not O2 or CO2 tables. It is a breathing regulation program, very good for controlling breath and relaxing for increasing depth and time as well as a less stressfulI way of training. If you want tables then use iholdbreath which allows you to practice tables. I use this as a warm up switch app do a table and then switch back. I have found this very effective.
