Dive deeper. Breathe smarter. Perform better. Naudic is your personal freediving coach – built by a freediver for freedivers. The app combines evidence-based training methods with the latest Apple technology, adapting automatically to your level after every session. Train smart CO2 tables build your CO2 tolerance, O2 tables improve your oxygen efficiency, and Free Static measures your maximum capacity. The adaptive algorithm analyses your performance and wellbeing after every session and calculates the optimal target for your next training – automatically, with no manual input required.
