Apnea Freediving Exercises 4+

Great App, Some Issues

So I live in Galveston, Tx and am currently going to school for Marine Biology with a minor in Scuba Diving. I originally downloaded this app to help me condition my breathing prior to any of my dive classes so I’d have a leg up on others in my classes when it came to free-diving. I took the initial test and started at 50 seconds, yet within 3 days of CO2 training I’d gone all the way to 2 minutes and 5 seconds. So in my opinion the app works great if you practice (I did it more frequently than the app recommended though)... I wanted to save the rest of my stuff in app so I decided to just pay for a year since it was cheap and I kinda liked the idea of a countdown since I hate looking at the timer... but the voice for the timer sounds awful and makes me uncomfortable! Not to mention I’d prefer more of a serious 10-15 second countdown going like 10-9-8-etc. than a whole minute of 10 second intervals. So since I’m still in the free trial I think I’ll just unsubscribe before the end of the trial and keep my own notes about my practices since the only things you can pay for aren’t even that great... That all being said, I 100% recommended this app! It is simple to use, easy to understand, and it does exactly what it’s meant to! I plan to use this for a long time indeed!

Thank you so much for the review!
I'm planning to experiment with timers and countdown functionality if you have a clear vision of how you would like to see them working, please feel free to send a short note to the email or just use the contact form both are available for the settings page. I'm always happy to hear suggestions for improvements.
I'm trying to keep the App as usable as possible for free users, so you are right that is not necessary to have an active subscription to get benefits from training.

Great training app

So this is simple enough you’d almost expect it to be free but:
1) It is really easy and effective. In one week my breathold has gone from 60 seconds to 3 minutes. I can’t wait for my next snorkel trip, and expect to be a lot higher on breathhold by then
2) yeah I could use a timer to do this but I wouldn’t in practice, so this rocks. I actually use if during my morning coffeee while surfing the news turning what used to be “wasted” time into a workout
3) it’s like $11 a year… for something that if you use it will really tweak your autonomic nervous system
4) No ads / just clean easy uncluttered functionality
5) it’s fun and easy to see your progress. An almost zen like feeling when you realize it’s been two minutes since your last breath and you are calm and present and have no need to breathe

Ps. Bonus #6 Have started Buteyko Breathing during my runs and aerobics. It is crazy efficient. But it works by boosting CO2 blood gas, so you feel like you are drowning because your ANS is telling you to gasp air like a dying fish because even though you’ve got plenty of blood gas O2 your CO2 is high. This is really helping with that, so an $11 app is also boosting my running, all while I drink my morning coffee… pretty cool stuff!

Many thanks for detailed feedback!

I'm keeping main functionality available for free, but have to charge for premium features to be able to keep working on improvements :)

Amazing results

Im not sure if this is normal or if it will be the same for every but i started off being able to hold my breath for 1:23. I then did one training session of each type (CO2 and O2). After that i decided to try another breath hold test and found that i was able to hold my breath for 2:46. I literally doubled my time in under an hour and I don’t know how that’s possible. I can now get to two+ minutes before feeling any slight discomfort and by the end of the month i'm hoping to be able to hold my breath for 3:30-4:15. I’m extremely impressed by this app and very glad that i tried it out.
