No subscription. No data leaves your device.

Train breath holds on your phone with guided sessions, CO2 and O2 tables, and a plan for your week. No watch or account needed for dry training. START WITH ONE GUIDED HOLD New to dry training? Begin with a guided first hold, with preparation, an untimed hold and recovery. You choose when to begin and end the hold. Already training? Open the exercise library and choose your session. TABLES THAT FIT YOUR STARTING POINT CO2 and O2 tables use your saved baseline to set hold times. Preview each session and read its instructions before you begin. Explore static holds and other exercises, each with its own guidance and requirements. FOLLOW THE CUES Voice and vibration cues guide your session. Review your holds afterward and keep your sessions, notes and personal bests in one logbook. MAKE ROOM FOR TRAINING Add an optional weekly plan, choose your training days and see your next session. You can also pick exercises yourself. KEEP YOUR HISTORY Review sessions and trends, export your data or save a backup. Cloud backup is optional and requires signing in. OPTIONAL GARMIN SUPPORT Supported Garmin watches and the separate inDepth watch apps add wrist-based dry training, heart-rate data, and pool and depth logs. Features vary by watch and app. Watch syncing requires Garmin Connect Mobile. See supported models and installation options at https://in-depth.app/install.
