Track your performance, navigate the water, and relive every dive. 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.
Your default mode lives in General Settings on iPhone, and the watch has its own settings for everything you set in the water. Pool recording and all of dry apnea training are free for everyone.
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.
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.
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. On iPhone, heart rate is charted across the whole session beside depth and temperature; drag one chart and all three move together.
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 peak descent and ascent speeds for the session, and the moment you hit each one. 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 interval, with a Smart mode that scales the wait to your last dive. Session time. Minimum 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, on iPhone or on the watch. After that there is nothing to remember and 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 saved location lands in the Locations tab on iPhone, on one map with your session starts and Dive Spots. Name it, add a note, copy its coordinates, or add it as a Dive Spot.
Dive Spot Navigation
Save up to 10 Dive Spots on iPhone and all of them reach your watch: tap a saved location in the Locations tab and Add as Dive Spot, rename it, or paste coordinates for a spot you have never dived. 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, spot name and live distance underneath. Press the Action Button for the next spot. For spearos and freedivers alike, that is the difference between finding the mark again and searching for it.
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 far you have drifted and which way to swim 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.
Your iPhone does the sending, so it needs to be nearby and online, on your buoy or in the boat. Updates go out each time you surface and lift your wrist clear of the water. The watch shows the share status. 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. A slow turn high above the site, then the camera drops in and chases your track as the line draws itself over satellite imagery and 3D terrain, then pulls back to reveal the whole route.
Your max depth, longest dive and dive count, the place and the date are set into the picture, 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, pool length and start depth are free. Default Discipline, the Dive, Rest, Breathe Up and STA alerts, and opening your sessions in full on the watch, on iPhone and on the web, are Pro features. 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.
Select it on your watch before entering the water: Start Pool, then Workouts. The watch counts down every rest and shows the set you are on, and a static hold buzzes at its target. Afterwards, the session page shows every planned set 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 make your own. Tap each contraction, and Progress shows how your holds, your first contraction and your heart rate change. Then open Equalise to learn how equalising changes with depth, plan your mouthfill and practise the drills on land.
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.
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.
Tap the star on any session to make it a favourite, then show only your favourites. The same logbook opens on iPad, and in any browser at app.freediveultra.com, where your settings can be changed too.
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.
Apple Watch Ultra pairs with an iPhone, never an iPad, so keep FreeDive Ultra on your iPhone too: it brings your dives in from the watch. Settings you change on iPad reach your watch through your iPhone.
