Every freediving feature, from first dive to logbook.
Apple Watch Ultra in the water. iPhone, iPad and your browser on land. Track every freedive, navigate the water, and relive it all. New here? Start with the setup guide.
The freedive.
Three modes, one tap
Open Water, Pool, or Dry Apnea. Select one on the home screen and tap once. That is the last time you touch the screen.
Set your default mode in Settings. Pool recording and all of dry apnea training are free for everyone.
Starts itself
Set Auto Launch to FreeDive and the session starts the moment you go under. Or press the Action Button to start one from the wrist.
Every dive after that is detected on its own. Two settings, set once.
Live Dive: it starts the moment you descend
The freedive depth screen. Every dive is detected automatically: the moment you descend it is tracking depth, descent and ascent speed, dive time, max depth and water temperature, second by second.
With Pro, back on iPhone every dive gets its own profile, second by second. Lay the temperature over the depth, then step from one dive to the next.
Full depth, from Apple Health
Live depth on the wrist reads to 6 m while Apple reviews our 40 m entitlement. Your watch still saves the full depth of every dive to Apple Health.
Seconds after you surface, FreeDive Ultra corrects each deeper dive from it, past sessions too. Allow Health access once: here is how.
Recovery
Surface, and a recovery timer starts alongside your live heart rate, so you know when you are ready to freedive again. Last depth and last dive time sit underneath.
The watch switches from Live Dive to Recovery and back on its own. With Pro, on iPhone heart rate is charted across the whole session beside depth and temperature; drag one chart and all three move together.
Your screens, your numbers
Choose what Live Dive and Recovery show. Turn a value off and the others grow: fewer values, bigger numbers.
Default, Minimal or your own, set on iPhone, on the watch or on the web. Choosing which screens appear, and their order, is Pro.
Session Overview
Dive count, session time and battery across the top. Max depth and longest dive in the middle, water temperature and calories at the bottom. Your whole freedive session at a glance.
On iPhone the same session opens in full: every number, the map and your route, your photos and video, conditions, notes and a rating.
Speed
Your last dive’s top descent and ascent speeds, and how long each took. Your live rate sits beside the depth on Live Dive.
Every dive's profile on iPhone carries its own speed data.
8 alarms you feel through a wetsuit
Max dive time. Target depth. Sequential depth. Surface time, with a Smart mode that scales the wait to your last dive. Session time. Min temperature. Hydration. Low battery.
Each one is a triple-tap you feel through a wetsuit, an amber pulse around the screen, and the metric that tripped it turning amber. Set them on either device; they stay in sync.
Stealth mode
The screen dims and haptics go silent as you descend. Full brightness returns the moment you surface.
One toggle in Open Water settings, then nothing to touch.
Navigate the water.
Save Location
A turn of the Crown drops a GPS pin exactly where you are, no tap required. Amber while it acquires, cyan when it is ready, green when it is saved.
Every pin lands in the Locations tab on iPhone, ready to name or make a Dive Spot.
Dive Spot Navigation
Save up to 10 Dive Spots on iPhone, from a saved location or pasted coordinates, and all of them reach your watch. Push one as your next-session target and the watch picks it up on its own.
The dial points relative to the way you are facing, with the spot name and live distance. The Action Button moves to the next spot. Find the mark again, every trip.
Locations
A tab on iPhone that puts every session start, every saved location and every Dive Spot on one map. Show Sessions, Saved or Dive Spots, or all three together.
Tap a saved location to name it, add a note, copy its coordinates or open it in Maps, then Add as Dive Spot to send it to your watch. The map is free; adding a Dive Spot is a Pro feature.
Route
Your path draws itself as you go, with the distance travelled. Press the Action Button to drop a marker at anything worth remembering: the hole, the wreck, where you left the float.
After the session the whole route is on the iPhone map, entry and exit points included.
Compass
Live bearing on a rotating tape. Press the Action Button to lock a heading, and the readout shows how many degrees you are off it and which way to turn back.
Your way back to the entry point, the boat, or the buoy, without lifting your mask.
Share.
Live Share
Send a web link and anyone can follow your session live: where you are, how deep you went, how long you held. No app needed at their end.
At the surface, press the Action Button to send a short message to their page, like “Heading back to shore.” Updates go out over your iPhone’s mobile connection, so keep your iPhone within range of your watch. Read the live location guide.
Share a session or a dive
Share a whole session or a single dive as a card, set over your photo with the title, max depth, longest dive and dive count. Or as a video, sized for Instagram and TikTok.
Straight to Instagram Story, Instagram Messages, TikTok, WhatsApp, Messages, or anywhere else through the iOS share sheet.
3D Flyover
Your route, flown by a drone: the camera drops in and chases your track as it draws itself over satellite imagery and 3D terrain, then pulls back to reveal it all.
Your swim distance, dive count and time held count up as it flies, over a profile of every dive, and it ends on a card. Rendered from any Open Water session with a route, as a video ready to post.
Pool and dry apnea training.
Pool
Choose DYN, DYNB, DNF or STA when you start. Every dynamic rep is detected automatically with its time and rest, and saved as one pool length. Swam further? Turn the Crown and save it with the Action Button. In STA, the Action Button starts and stops each hold.
Underwater the Action Button is a stopwatch. Recording is free; Default Discipline, pool alerts and opening sessions in full are Pro. Read the pool freediving guide.
Pool workouts
Static CO2 and O2 tables for STA, or your own workout for DYN, DYNB, DNF or STA: sets of apnea and rest, built on iPhone in Train, then Pool.
On the watch: Start Pool, then Workouts. It counts down every rest, and a static hold buzzes at its target. Afterwards, every planned set sits beside what you did.
Dry apnea
Find your max breath hold, then run CO2 and O2 tables built from it, at Easy, Normal or Hard, or build your own round by round. Tap each contraction, and Progress shows how your holds, your first contraction and your heart rate change.
Train is a tab on iPhone and iPad, with voice cues. On the watch, tap Start Dry Apnea and choose Free Hold or a table; your max and your tables come from Train. Read the dry apnea training guide.
Equalise
Valsalva, Frenzel, mouthfill and reverse packing, in order, with the depth each one suits. Plan your charge with the mouthfill calculator.
Then practise on land with voice-guided drills: Frenzel reps, a control ladder and a mouthfill rehearsal. In Train, on iPhone and iPad.
Back on land.
Logbook
Every session in one list, with your lifetime stats up top. Search by place, title or notes, filter to Open Water, Pool or Dry, and sort by newest, deepest or longest dive.
Star your favourites and show only those. The same logbook opens on iPad and at app.freediveultra.com, where your settings can be changed too.
Your data, your way
Every session is saved to Apple Health as a workout, so it counts in Apple Fitness. Bring your history from Suunto, Garmin, Oceanic+, Atmos or any UDDF file; export in UDDF with Pro.
A free account backs up everything, photos and videos included, and opens your logbook at app.freediveultra.com. Demo dives on both devices let you try every screen before you get wet.
iPad
FreeDive Ultra runs on iPad: your logbook and settings side by side, your maps and Train on the bigger screen. Sign in with the same Apple Account as your iPhone and your sessions arrive through iCloud.
Keep FreeDive Ultra on your iPhone too: Apple Watch Ultra pairs with an iPhone, which brings your dives in and passes iPad settings to the watch.
