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.

Upd: going to fix skipping in next release, thanks for feedback. Greetings, we already refactored square timer for stable notifications, and going do this with table timer also - all our test phones work correctly with oximeters, but if we find device with such issue we try to fix that Hope to live up to expectations

Great so far. In 3 days I have doubled my breath holding time (complete beginner). Only suggestion to app interface is when creating a new table, the trashcan for deleting a row gets covered up by the add new row button and is difficult to press. Might want to relocate 1 of the 2. Thanks so much for your work!

10-11-20 What a disappointment. I had hope the problem was with my phone, so I'd restart the phone prior to starting the exercise. It didn't help, the app would randomly stop during the later rounds (very frustrating). No way would I pay for the premium app if the free app is so flakey. Deleting the app from my phone. 9-29-20 What happened? The app was great, but has started to fail and exit in the middle of the training. The countdowns have also been glitchy. Is it my phone or the app?
