About this app
Apnea Core helps freedivers keep track of their training, understand their progress, and build more structured habits over time.
Whether you train static, dynamic, depth, dry sessions, or CO₂ and O₂ tables, Apnea Core gives you one place to log what you do and see how your performance evolves.
LOG YOUR TRAINING
Keep a complete record of every session: discipline, depth, time, water temperature, buddy, notes, and more. Your personal bests are updated automatically, so you can follow your progress across different types of training without using spreadsheets or scattered notes.
UNDERSTAND YOUR PROGRESS
After each session, Apnea Core helps you read your data through simple performance indicators such as Comfort Index, Recovery Efficiency, and CO₂ Tolerance. The goal is not to replace your own judgment, but to give you clearer feedback on how your training is developing.
FREEDIVER INTELLIGENCE
Get an automatic training digest, free for every user, that updates as soon as you log a new session: training frequency and session difficulty trends, personal best stagnation compared to your training load, and your CO₂ vs O₂ balance across static tables, all with clear charts, no guesswork.
TRAIN WITH MORE STRUCTURE
Get session-based guidance that helps you decide whether to maintain your current rhythm, take more recovery, or gradually increase the challenge. Recommendations are based on your logged metrics, not on a generic training plan.
TRAIN WITH OTHERS
Share sessions, follow other freedivers, join groups, and take part in training events. Compare your personal bests across disciplines in a way that supports progress without turning everything into a competition.
PRIVACY FIRST
Your data stays yours. Apnea Core has no ads, does not sell your data to third parties, and lets you delete your account permanently whenever you want.
Apnea training should always be done safely, with proper supervision and never alone.

What’s new
What's New:
Training: O2 and CO2 tables are now built from your own static personal best. The hardest round is anchored to a safe percentage of your maximum, so picking more rounds makes a session longer without making it harder: previously more rounds also raised the peak, with nothing to say so. Spoken session prompts follow the app's language, and the Wonka table resumes from your calibration instead of starting over.
