Simple app but needs improvement

Good simple app to train tables. I wish the the app would use the conventional O2 tables (8 sets of 2 min ventilation, x seconds of apnea increasing by 15 sec) and that the app came pre-loaded with them so you could skip the “training” and pick up where you want. Similarly wish the were conventional co2 tables pre-loaded, plus I’d be nice with a Wonka style Co2 exercise with only a single recovery breath. Also wish the app would count up instead of down during apnea and tell me to “breathe”. Finally, one annoying issue with this app is that it wont stop the iPhone from going to sleep, hence you have to shut off the auto-lock/sleep function to use this app.

Great! But....

It could be better in a few ways.

There needs to be a help/info screen so I know what I am doing.

Also I would like to have a support area to message my questions to people that can help me, such as what's the difference between the co2 and the others? Why would I need to make my own chart? What do I need to keep in mind while making my own chart? How often do I need to do this exercise? Do I do the mixed exercise all the time or a different one a day?

I believe this is the best apnea app out there, however I want to know the best way to get me to be able to hold my breath longer. I'm at about 3min now but I want it at 5. What should I be doing the most?

Also there is a bug that makes the sound bar disappear, need that to come back.

I have all the apnea apps and this is my favorite. Just do a few things and it will be perfect. Thx!

Improves your performance fast

Great app! In just 3 days of using and doing all 3 sessions a day, my breath hold record increased by 30 seconds. If you are dedicated and complete all sessions regularly, you will see improvements in your dives. Worth the 3 dollars for sure!
