U-Dive is an Apple Watch companion for freediving and snorkel training. Put on your watch, get in the water — it handles the rest. ◆ On Apple Watch • Automatic submersion & dive detection — recording starts hands-free • Live depth and water temperature (depth display capped at 6 m in this release) • Continuous heart-rate recording during dives — watch your mammalian dive reflex • Surface-interval timer with haptic surfacing alert • Custom depth alerts with haptic feedback • Personal max-depth record notifications • GPS entry/exit coordinates for every dive • Action Button support: start a session, flag a dive, review history • Auto Water Lock — long-press the crown to end & save • Built-in dive simulator to try the full flow on dry land ◆ On iPhone • Dive-spot map with favorites, notes and custom icons • Import Google My Maps layers (KML) • Paste a Google Maps share link to create a spot • Full dive log: depth profile, heart rate, duration and coordinates • Share and export your dives ◆ About Lite This release uses Apple's shallow-depth API: depth display is capped at 6 m, while time, heart rate and GPS keep recording beyond it. A full-depth version is in progress. ◆ Requirements • Depth and auto dive detection require an Apple Watch Ultra (depth gauge) • Other Apple Watch models work in manual mode (HR, GPS, timers, log) • The iPhone app manages spots and logs; the watch app runs independently ◆ Safety This app is not a dive computer and must not be used for dive safety or decompression decisions. Not for scuba diving. Freediving is dangerous — never dive alone, follow one-up-one-down, and get certified training.
