Apnea Tables – this is an app for the training of the breath holding in static air (static apnea) for spearfishers and freedivers.

The App will work automatically. In order to individualize a training you first need to make an attempt with the maximum breath holding. To start take 3-4 warm-up attempts (about half the time of your maximum score). Then hold your breath maximally and save the result of your maximum breath holding. On the basis of this maximum breath holding training tables will be automatically calculated (table CO2 and table O2).

There are 2 basic tables. The table CO2 helps to accustom the brain to the high level of CO2. The table O2 helps to accustom the brain to the lower level of O2.
The table CO2 is a series of static breath holdings with the decrease of the rest time at a constant breath holding time.
The table O2 is a series of static breath holdings with the increase of breath holding time at a constant rest time.

Apnea Tables integrates with the Apple Health app to sync your workouts.
