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 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?

Nice app! I must say it is very well amde and plenty of features, sadly as many others, when I connect my Garmin Forerunner 245 music I don't get hr reading on the app, even though it opened the app from my watch. Restarting the watch sometimes works but then It block mid training so not really useful. I'll change to 5 star if this issue is fixed.
