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. Back at the surface, the dive reaches your iPhone with its profile, its map and the weather at the time.
crazyDive is not a dive computer: it does not calculate decompression or limits. Always dive with your dive computer and within your training.
What crazyDive does
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.
Starts and saves on its own
Choose Dive or Snorkel and go under: recording starts when you enter the water and locks the screen. At the surface, a countdown saves it on its own; if you go back down first, it stays the same dive.
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 of every dive
The weather and air temperature for the time and place of the dive are added automatically.
Your complete logbook
Gear (weights, pressures, gas, tank, wetsuit), buddy, notes, photos and tags. You can also add dives by hand.
Statistics
Your deepest and longest dives, the coldest and warmest water, activity over the last 12 months and the depth distribution.
Calendar, search and sites
Search and filter by type, date, depth or tags; see your dives on a calendar or on a map of all your sites.
Export, import and back up
Export to UDDF (Subsurface, DivingLog…) or CSV, import from UDDF and save a full backup to Files or iCloud Drive.
iCloud and Siri
Your dives, safe in your own iCloud account, and back again if you change iPhone. Ask Siri about your last dive.
