Apnea Tables is a powerful breath‑hold training app designed for freedivers, spearfishers, surfers, and anyone looking to improve their static apnea performance.

The app automatically builds personalized CO₂ and O₂ training tables based on your maximum breath‑hold time, helping you increase comfort, control, and mental tolerance during long breath holds.
Personalized Breath‑Hold Training.

To generate your custom training plan:

Perform 3–4 light warm‑up breath holds.

Complete one maximum breath‑hold attempt.

Save your result — the app instantly creates individualized CO₂ and O₂ tables tailored to your level.

CO₂ and O₂ Tables Explained

CO₂ Table
Builds tolerance to rising carbon dioxide levels.
Rest time decreases while breath‑hold duration stays constant.

O₂ Table
Improves comfort at lower oxygen levels.
Breath‑hold duration increases while rest time stays constant.

These two core tables are widely used by freedivers and spearfishers to safely increase breath‑hold capacity and mental resilience.

Additional Training Modes:

Triangle breathing

Box (square) breathing

Apnea Walking

Adjustable training parameters

Voice cues, vibration alerts, and sound notifications

Perfect for relaxation, focus training, and controlled breathing practice.

Apple Health Integration.

Apnea Tables syncs your breath‑hold sessions with the Apple Health app, allowing you to track progress and monitor your training history in one place.

Train smarter, breathe deeper, and improve your static apnea with Apnea Tables - your personal breath‑hold coach.

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.
