How It Works Watch iPhone Depth Free vs Pro
Designed for Apple Watch Ultra

FreeDive Ultra

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

Dive in. We handle the rest.

FreeDive Ultra is designed around one principle: water lock disables all touch input. So everything is fully automatic.
01

Start a session

Tap once on your Apple Watch Ultra before entering the water. Water lock activates. FreeDive Ultra begins monitoring.

02

Just dive

Every descent is detected automatically. Depth, time, and temperature are tracked second by second. Surface intervals start the moment you break the surface. The Digital Crown scrolls between screens.

03

Review on iPhone

Sessions sync automatically. Dive into your session stats, then explore individual depth profiles for every dive. Add photos, rate conditions, and log notes. See your swim route on a map and revisit any locations you pinned during the session.

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

Six live session screens — plus a look at alarms, stealth mode, and the on-wrist logbook. Click the Digital Crown or use the arrows to explore. The watch auto-switches based on whether you’re diving or at the surface.

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 automatically from your Apple Watch. Your complete dive history, in detail. 11 screens — use the arrows to explore.
