About this app
DiveOne turns your iPhone and Apple Watch into a clear, portable dive logbook. WHAT IT IS DiveOne records shallow dives natively on supported Apple Watch models, up to the current 6 m app limit. Completed dives can also be imported from Apple Health. Review depth, time, temperature, site, notes, and the recorded profile in one place. APPLE HEALTH With permission, completed Apple Watch dives are saved as underwater workouts. On iPhone, DiveOne can read underwater workouts and underwater depth data from Apple Health for import. OWN YOUR DATA Export a dive-summary CSV with one row per dive. Create and restore a DiveOne JSON backup. An account is optional for on-device recording and logbook use. DIVE SITES AND OPERATORS Browse dive sites and the dive centres and boats that operate there. Directory entries do not imply endorsement by DiveOne or by a listed operator. WHAT DIVEONE IS NOT DiveOne is a dive logger and logbook. It is not a dive computer. It does not provide decompression, no-decompression limits, ascent-rate guidance, or safety-stop guidance. Always dive with and follow your own independently certified dive computer, training, and local procedures. Free to use. The app is currently unavailable in EU App Store storefronts.
