The freedive.
Three modes, one tap
Open Water, Pool, or Dry Apnea. Pick 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 and dry apnea recording 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 rate, 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 rates 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 pin lands on the iPhone map, and all of them together become your atlas: every spot you have ever marked, on one world map.
Dive Spot Navigation
Curate up to 10 sites on iPhone and all of them reach your watch: promote a saved pin in one tap, 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.
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.
Pool and dry apnea training.
Pool
Counts every length and totals your distance automatically. Save a length with the Action Button mid-swim, rest between efforts on a timer, and set a rest target so the watch tells you when to go again.
Underwater the Action Button is a stopwatch; at the surface it saves the length you dialled. Pool length and start depth are set in Training Settings. Recording is free; the session review on iPhone is Pro. Read the pool freediving guide.
Dry apnea
A guided breathe-up counts you in, one button on the screen starts and stops the hold, and your personal best is tracked as you go. Anywhere, any time, no water required.
Breathe-up is set in Training Settings on either device; your personal best is edited on iPhone.
