Imagine seeing large, colorful fish swimming 6 meters below the surface while snorkeling at sea. Wouldn’t it be great to be able to dive deeply with one big breath and take incredible pictures for your friends at home? The Apnea Trainer makes it possible! By using it to train three times a week, you can quickly double your underwater time.

This is the same training principle used by apnea divers. It’s based on a yoga technique which strengthens the diaphragm muscles allowing you to fill your lungs with more oxygen and releasing more carbon dioxide while exhaling. The system is relatively simple and depends on finding the right time intervals which are provided by the program, thus letting you relax and concentrate on your breathing. This will guarantee maximum training success.
The program will also come in handy just before the actual dive since a pranayama mode is already included. The Apnea Trainer will help you keep your whole body calm and give you the perfect preparation for those amazing, long-lasting dives.

Gets the job done, but worth the $???

UPDATE: timer is now defaulting to 23:05:00 vs 00:05:00 as the developer has indicated is the default below. No response to emails sent with screenshots of such. While it’s a minor issue, there’s simply no need for a timer to even go to these ranges. A better setup would be to emulate that of the recent change to iOS where a user can set hours, minutes, and seconds.

First, I don’t free dive but needed something that would give me focused breath control practice.

This app is pretty simple but gets the job done. For my purpose, at least. I use it for a guided relaxation breathing practice because I’m lousy about doing it on my own.

It does have a couple quirks:
1. The timer isn’t labeled so you have no idea that the left number is HOURS and the right is MINUTES. And for some reason, it defaults to 17:05:00.

17 HOURS!?!?!?

2. The instructions for the app are lacking and some of the App Preferences (AM/PM time) have no explanation of what they do so you have to toggle them on/off and “search” for what change took place.

Overall, don’t know that’s its worth $2.99 though.

Hi Chi Chi, the default is actually 5 minutes. Would be nice if you could contact the support to find out what caused this issue. AM/PM is for our friends in the USA, instead of 16:00 you will see 4 pm. If you have questions feel free to contact me using the support or FB.

Excellent App


I bought this app to help with my physical performance. It is great to use as a timer for the breathing protocols. I believe I originally heard it mentioned by Tim Ferriss or Gabby Reese in a podcast or interview. It does everything I need it to.



So I started at one minute with comfort but after 14 apnea breath ups I went to 1.5 minutes like it was nothing! The important thing is to do a breath up BEFORE holding which I think a lot of negative reviewers forgot about. There's also three types one for apnea one for prior the breath hold and another called "pro" I don't really understand. You also get an autograph for the stop watch. For three bucks you get a coach to count you through the holds and a graph that's mostly automatic. Not bad. This is a basic app, but worth the money. I hope to see future updates to better define the purpose of each exercise or better frame the students goals. Without outside reading it's hard to know how you should be goal setting .
