Designed for Apple Watch Ultra

FreeDive Ultra The freediving and spearfishing app for Apple Watch Ultra

Dive tracking that works the moment you hit the water. Zero touch required. Just dive.

How It Works

Dive in. We handle the rest.

FreeDive Ultra is the only app built exclusively for freediving and spearfishing on Apple Watch Ultra. Water lock disables all touch input, so everything is automatic: tap once before you enter the water, and never touch the screen again.

Start a session

Open water, pool, or dry apnea. Pick your mode and tap once on your Apple Watch Ultra. Water lock activates. FreeDive Ultra begins monitoring.

Dive or train

Every dive and breath-hold 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

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. See your route on a map, revisit any locations you pinned, and curate up to 10 dive sites to navigate to from your watch.

On Your Wrist

Everything you need at depth. Nothing you don’t.

Every screen on the watch, from the dive itself to recovery, navigation, Live Share, alarms and pool training. Click the Digital Crown or use the arrows to explore. Underwater and surface switch on their own.

Live Dive

The only screen you see while underwater. Current depth (cyan), descent or ascent rate beside it, dive time, and a running max depth and water temperature at the bottom. Everything you need at depth, nothing you don’t.

The dive doesn’t end at the surface.

Sessions sync from your watch on their own. Every dive in detail: stats and charts, second-by-second profiles, your route and saved locations on a map, photos and video. Share cards, Live Share, your curated dive spots, and a logbook that moves in and out in UDDF and into Apple Health. Use the arrows to explore.

Questions

What freedivers ask.

Which Apple Watch does FreeDive Ultra work on?

Every Apple Watch Ultra: the original, Ultra 2, Ultra 3 and Ultra 4. It runs on the depth sensor, and only the Ultra has one.

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 and 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 true depth, so your logbook is right. Every other feature works at any depth.

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.
