FreeDive Ultra is the only app built exclusively for freediving and spearfishing on Apple Watch Ultra. Open water, pool and dry apnea modes. Tap once before you enter the water. Every dive is tracked automatically, and you never touch the screen again. THE DIVE The moment you descend, it starts tracking: depth, dive time and water temperature, second by second. The watch switches to Live Dive on its own, then back to Recovery when you surface. A timer counts your surface interval alongside your live heart rate. ZERO TOUCH, BY DESIGN The Digital Crown moves between screens. The Action Button acts on whichever screen you are looking at: set your heading on the compass, cycle to the next dive spot, drop a marker on your route, or save a length in the pool. NAVIGATE THE WATER Save a GPS pin with a turn of the Crown, no tap required. The Route screen tracks your path as you go and shows how far you have travelled, with every marker you dropped on the Action Button laid along it. Curate up to 10 dive sites on iPhone and all of them reach your watch. Cycle through them with the Action Button, and navigate to any one with live direction and distance on the dial. For spearos and freedivers alike, that is the difference between finding the mark again and searching for it, and a map of everywhere you went. LIVE SHARE Send a web link and anyone can follow your session live: where you are, how deep you went, how long you held. Your iPhone sends it, so keep it nearby and online, on your buoy or in the boat. Updates go out each time you surface. POOL AND DRY TRAINING Pool mode counts every length and totals your distance automatically. The Train tab: take a breath hold test, then follow CO2 and O2 tables built from your max, or make your own, with a voice talking you through each round. Run them on iPhone with your watch heart rate, or on the watch. BACK ON LAND Sessions sync to iPhone on their own. At a glance: dive count, max depth, longest dive, session time, plus calories, heart rate and duration written to Apple Fitness via HealthKit. See your route on a map with total distance, entry and exit points, and every location you saved. Add photos and video, log visibility, current and surface conditions, write notes, and rate the session. Session Charts show heart rate, depth and water temperature across the whole session. Every dive gets its own profile, descent and ascent rates, and surface heart rate. YOUR LOGBOOK ON THE WEB Every dive, map and note on a big screen, and you can edit them there too. Sign in at app.freediveultra.com DEPTH Depth reading is capped at 6 metres while we work with Apple on the full 40m entitlement. Every other feature works identically at any depth. FREE VS PRO The free tier is a real dive watch: automatic tracking, real-time depth and dive time, surface recovery with live heart rate, pool training, dry apnea training with CO2 and O2 tables, your dive list on iPhone, iCloud backup, demo dives and UDDF import. No subscription, no time limit, no catch. Pro adds the rest. On the watch: session overview, descent and ascent speed, compass, Route, dive spot navigation, saved locations, 8 haptic alarms, Live Share, and automatic stealth mode that dims the display and silences haptics the moment you go under. Tune it with configurable session timeout, custom surface screens and Crown sensitivity. Plus pool length, rest and target times. On iPhone, Pro opens every open water and pool session in full, and every dive inside it. Share a whole session or a single dive as a card or a video, sized for Instagram and TikTok, or replay a dive as a 3D Flyover. Export in UDDF, the standard dive log software reads worldwide. 7-day free trial. Built by a freediver, for freedivers and spearos.
