Review intelligence
Medium confidenceUsers praise the app for improving breath hold times and ease of use, but many desire better Apple Watch integration.
This is a great app that offers a lot of value for free. Custom O2 and CO2 tables are very easy to use. The structure of the workouts is very helpful and encourages progression.
As a free user this is really annoying. The popup to pay pops up every single time I open it. Also the volume is not adjustable and that’s frustrating too. I’m deleting it for an app that isn’t like this.

Questions this record can answer
How was every figure on this page produced?
Each figure is read from public App Store metadata or computed from it, dated to when we read it, and traceable to a stored row. Percentiles, cadence, longevity and sentiment are derived by us; ratings, prices, sizes and dates are taken as the store reports them.
Why can the star average and recent opinion disagree?
The star average is cumulative over the app’s whole life, so recent opinion barely moves it. Any sentiment figure we compute reads only recent review text, which is why it turns first. Treat a divergence as an early indicator, not a verdict.
What can this page not tell you?
Downloads, revenue, active users, subscription pricing inside the app, and anything about security or data handling. None of those are visible in public store metadata, so we do not estimate them.
