Why Training with Aegean?

We combine professional freediving principles with modern technology to help you safely extend your limits.

Auto-Generated Tables

Based on your personal best, we calculate the perfect CO2 and O2 tables to push your limits safely without overtraining.

Bluetooth Heart Rate

Connect your HR monitor to see exactly how your body reacts to low oxygen. Visualize your dive reflex in real-time.

Eyes-Free Training

Guided by "Alfie", our voice assistant. Haptic vibrations and audio cues let you train without looking at your device for maximum focus.

Contraction Tracking

Log when your contractions start. Analyze your tolerance phase and learn to get comfortable with the uncomfortable.

Offline & Private

Your data stays on your device. No accounts, no cloud sync, no internet required. Train anywhere, even on a boat.

Modern Interface

Built with Material Design 3. A beautiful, dark-mode-first experience that's easy on the eyes.

Simple Approach

Set Your Baseline

Perform a simple "Best Effort" test. We use this single data point to calibrate the entire app to your current fitness level.

Select Your Goal

Choose CO2 tables to build tolerance to the urge to breathe, or O2 tables to adapt to low oxygen levels.

Follow the Guide

Start the table. Alfie (audio guide) will tell you when to breathe and when to hold. Just relax and follow along.

Safety Warning

NEVER practice breath holding in water, while driving, or standing up. Always train dry, lying down on a soft surface like a bed or sofa. Blackouts can happen without warning. Train safe.
