crazyDive

crazyDive is your dive and snorkel logbook. Put on your Apple Watch, choose Dive or Snorkel and go under: depth, water temperature and GPS position are recorded on their own. When you surface, the dive reaches your iPhone with its profile, its map and the weather at the time. STARTS AND SAVES ITSELF Recording starts when you enter the water and locks the screen so the water can't trigger touches. When you surface, a countdown saves the dive by itself; if you go back down before it ends, it's still the same dive. DEPTH AND TEMPERATURE The watch measures depth and water temperature throughout the dive. On dives deeper than 6 m, crazyDive completes the profile with the depth that Apple Watch Ultra itself stores in Health. ON THE MAP Every dive is pinned with the GPS position where you went in and came out, on a surface or sea-floor map. And all your dive sites together on one map. THE WEATHER FOR EVERY DIVE The weather and air temperature for the time and place of the dive are added on their own. YOUR COMPLETE LOGBOOK - Gear: weights, pressures, gas, tank and wetsuit. - Buddy, notes, photos and tags. - Dives added by hand, even without a watch. - Statistics: your deepest and longest dives, the coldest and warmest water, the last year's activity and the depth distribution. - Calendar, search with filters and a map of all your sites. EXPORT, IMPORT AND BACK UP Export to UDDF or CSV to open your dives in other dive software, import from UDDF and keep a full copy in Files or iCloud Drive. YOUR DIVES ARE YOURS They stay on your devices and, if you want, in your own iCloud account. No account, no servers, no analytics, no ads. In 16 languages. REQUIREMENTS Apple Watch with a depth sensor (any Apple Watch Ultra, or Apple Watch Series 10 or later) running watchOS 26 or later, and an iPhone with iOS 18 or later. Without a watch, crazyDive works as a logbook: you can add dives by hand and import them from UDDF. IMPORTANT crazyDive is not a dive computer: it does not calculate decompression or limits. Always dive with your dive computer and within your training.
