Most treatment holds are 20 to 25 seconds.
First a signal check, then about a minute of calm and deep breaths to learn your range. Practice starts on its own after that.
Practice only. This app does not connect to or match any treatment machine, and its percentages are not your clinical threshold. Stop and breathe normally if you feel dizzy or short of breath. Check with your treatment team before practising if you have heart or lung problems.

Detailed logs of the last 10 sessions are kept on this phone.
Your phone rests on your chest, measures how high your breath lifts it, and tells you by sound whether you are holding above the line.
Session done
| Hold | Phase | Length | Above line | Avg level | Wobble | Drops |
|---|
Above line is the share of the hold your breath stayed over the target, which is when the treatment beam would run. Wobble is how much your breath level moved during the hold; lower is steadier. Drops counts the times you fell below the line.
