About
Apnea Assistant is widely regarded as the most complete freediving training app available, built by professional instructors at the Freedive Academy Panglao — one of the world's leading freediving instructor training centers. Designed for everyone from absolute beginners to elite competitive freedivers, the app takes a holistic approach to breath-hold training by combining structured CO2 and O2 training tables, guided breathwork sessions, and stamina exercises into a single distraction-free tool. The app features a powerful personal logbook that lets users record every training session, static breath-hold, exercise, and personal best. Beyond raw numbers, users can log how they felt during each session, track sensations, and monitor their progress over time to identify patterns and stay motivated. Apnea Assistant also includes a comprehensive Learning Center with nearly 30 articles covering the science of breath-holding, technique refinement, training table explanations, and personalized guidance for all skill levels. Whether you are building CO2 tolerance, developing O2 efficiency, working on lung development, or pushing toward new depth records, the app provides the right tools for a well-rounded practice. Compatible with all iOS and Android smartphones and tablets, Apnea Assistant is committed to remaining completely free forever — no hidden fees, no premium paywalls, and absolutely no ads.
