Spearfishing on
Apple Watch Ultra
Turn the Crown to drop a GPS pin on the spot. Next trip, the watch points you back to it. Built by a spearo, for the Apple Watch Ultra you already wear.
Mark it. Come back to it. PRO
The loop every spearo runs, on the wrist. These are the app’s real screens; press the Action Button to try them.
Turn the Crown on the spot
A GPS pin drops exactly where you are: the only way on Apple Watch Ultra to save a spot without touching the screen. Amber while it finds you, cyan when ready, green when saved.
The dial points you back
Make it a Dive Spot and the dial points the way to swim, relative to where you are facing, with the distance live. Up to 10 spots.
Action Button: next spotEvery pin lands on your iPhone in the Locations tab. Name it, copy its coordinates, or add it as a Dive Spot, and it reaches your watch. Push one as your next-session target and the watch picks it up on its own. You can also paste coordinates for a spot you have never dived.

What spearos say
Reviews quoted as written, by spearfishers using the app on their own sessions. Each name links to the App Store reviews.
The save pin feature is what makes it for me. When I'm out spearfishing and find a good spot, I drop a pin from the watch and it's on the iPhone map next trip. No phone in the dry bag. Use it every session.Scotty-gb1, United Kingdom
Used this app on multiple spearfishing outings, and the app really supports surface recovery times and logs detailed dive parameters.Hawai’i Spearfishing, United States
This is a great app, they’ve clearly thought through what spearos need. Smart features. It’s cool.rosstafurrrrrrrr, United Kingdom
The app was launched on r/Spearfishing, where spearos told me what was missing.
What spearos ask
Does Apple Watch Ultra work with gloves on?
Yes. Nothing in a session needs the touchscreen. Dive detection, screen switching, recovery and stealth mode are automatic. Saving a location is a turn of the Digital Crown, and route markers, dive spot switching and the compass heading lock are all on the Action Button. Both work through gloves.
Do I have to start and stop each dive?
No. With Open Water selected on the watch, one tap on Start Freediving begins the session, or it starts on its own when you descend with Auto Launch on. From then on every dive is detected automatically: descending starts it, surfacing ends it, and the recovery timer starts the moment you are up.
Can I mark a spot I want to come back to?
Yes. Where the fish were, a cave, a ledge, a wreck, anything worth a second visit. Surface and turn the Digital Crown to save a GPS pin exactly where you are. It lands in the Locations tab on iPhone after the session, and you can add it as a Dive Spot the watch will navigate you to next time. The Route screen also lets you drop a marker on your track with the Action Button, for the session in hand; markers stay on the watch, pins are the ones that are saved.
Which Apple Watch does it work on?
Every Apple Watch Ultra: the original, Ultra 2, Ultra 3 and Ultra 4. FreeDive Ultra is for Apple Watch Ultra only.
How long does the battery last?
Around 10% an hour, so a full charge covers every session. A low battery alarm taps you at 20%.
Does it replace a buddy?
No. One up, one down, always. The watch tracks your surface interval and taps you when it is time; your buddy watches you. Live Share lets anyone with the link follow the session, but it is a window on the session, not a safety system. Messages are not monitored and nobody is alerted when one arrives.
