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.

I have used it for a long time (Paid). It has everything needed for anyone to practice. I wish it was better by being able to use Google health, Samsung watch, or any other device for SpO2 and heart rate. While not imperative, I paid because I saw it could do Bluetooth or could use Google health. This app is blocked from Google health and all other devices that it could have paired with are mostly obsolete. This app is good, but it has the potential to be great.

I don't know how to explain it, but sometimes seconds run too fast. It is like the seconds in this app a bit shorter then real. Maybe I am crazy. I feel it every training. And one more. Every training I add one sec to holding time. Usually I have 8 laps, so I need 8 times to change the time (add 1 sec). It makes me crazy. Is there any way to change all laps at once?
