I've been using this app for years, and it's still my favorite apnea trainer. I like the flexibility to create my own tables. Most other apps don't allow you to adjust ventilation and apnea time on the same table. Previous problems have mostly been ironed out. I learned through experience that voice prompts will be less accurate or skipped if you make the app tell you too much in quick succession, like signalling the start of contractions with 30s remaining, or setting an apnea time of 2:00.

In new version 2.0.0 we completely changed timer and notification logic in table mode. It should work stable now.

update after 2yr: Had to review this again against the available breath hold trainers on the market. Still the best out there. The dev is definitely on top of fixing bugs and 99% of the time it just works. re-review: Tried this a year ago and reviewed it poorly. This is the cleanest interface apnea trainer and since redownloading I have had no issues. Old rev: Opens several adds simultaneously with no input and crashes the app rendering it totally useless.

Upd: Thank you for taking the time to feedback! Sorry by that and thanks for feedback. I suppose this is bug in ad module. Already posted to company which provide ads. Would be great if you send screenshot to my email. I do not updated app more than month but this bug appear only now.

Exactly what one needs. The only missing bit is the total duration time for the tables.
