Dive in. We handle the rest.
Start a session
Open water, pool, or dry apnea. Select your mode and tap once, or let Auto Launch start the session as you submerge. Water lock activates. FreeDive Ultra begins monitoring.
Dive or train
Every dive is detected automatically. Depth, time, and temperature tracked second by second. A recovery timer starts the moment you break the surface. The Digital Crown moves between screens, and the Action Button acts on whichever screen you are looking at.
Review on iPhone, iPad or the web
Sessions sync automatically. Dive into your session stats and charts, then explore individual depth profiles for every dive. Add photos and video, rate conditions, and log notes. The Locations tab puts every start, saved location and Dive Spot on one map, and Train holds your dry apnea tables and pool workouts. Your whole logbook opens on iPad too, and in any browser.
Everything you need at depth. Nothing you don’t.
Live Dive
The only screen you see while underwater. Current depth (cyan), descent or ascent speed beside it, dive time, and a running max depth and water temperature at the bottom. Everything you need at depth, nothing you don’t.

What freedivers say
Does what I need without all the scuba stuff that clutters up other apps. The iPhone logbook is handy for looking back at where I've been and how the session went. Worth it if you already wear an Apple Watch UltraWill & Bea, United Kingdom
It is simple to set up and simple to use. It is clear that it was developed for free divers and it is not just another scaled down scuba diving app. The most important part is excellent support.Nevengal, United States
Cracking app Could pinpoint all our little dives, my partner loves it. And it pops up on our iPhone map for our next trip! Well done guys!!!WaterAngel78, United Kingdom

What freedivers ask.
Which Apple Watch does FreeDive Ultra work on?
Every Apple Watch Ultra: the original, Ultra 2, Ultra 3 and Ultra 4. FreeDive Ultra is for Apple Watch Ultra only. New to freediving with it? Read Is the Apple Watch Ultra good for freediving?
Is FreeDive Ultra free?
Yes. The free tier is a real dive watch: automatic tracking, real-time depth and dive time, surface recovery with live heart rate, pool recording, dry apnea training, your dive list on iPhone, iCloud backup, demo dives and UDDF import. No subscription, no time limit. Pro adds the rest, with a 7-day free trial.
How deep does it read?
Live depth on the wrist reads to 6 metres while we work with Apple on the full 40m entitlement. The moment you surface, each dive is corrected to its full depth, so your logbook is right. Every other feature works at any depth. The correction comes from Apple Health: if deeper dives stay at 6 m, the setup guide’s troubleshooting shows how to turn on Health access.
How do I set it up?
Install the watch app, allow the three permissions it asks for, then run Watch Setup on iPhone. Auto Launch starts a session when you submerge, and the Action Button is yours to assign. The setup guide walks through all of it.
Do I have to touch the screen in the water?
No. Water lock disables touch, so dives are detected automatically. The Digital Crown moves between screens and saves a pin, and the Action Button acts on whichever screen you are on. Both work through gloves.
Can I bring my existing dive log?
Yes. Import any UDDF export on iPhone, from Oceanic+, Shearwater, Suunto, Garmin, Atmos or any dive app or computer that writes UDDF, and every session appears with its full depth profile. Import is free. Export is Pro.
Does it work on iPad?
Yes. FreeDive Ultra runs on iPad: your logbook and settings side by side, your maps and Train, on the bigger screen. Apple Watch Ultra pairs with an iPhone, never an iPad, so keep FreeDive Ultra on your iPhone too. Your sessions reach the iPad through iCloud when both use the same Apple Account.
