01 — Beyond the photo roll
A catch is more
than a picture.
Behind every catch there is a dive: the sea that day, the spot, the wait, your buddies. SpearfishOS keeps it all in one place. And a day with no catch deserves its page too.
Keep your landmarks
Save your spots on your personal map. They stay on your phone: nobody else sees them, they are never published.
Relive a season
Scroll back through your dives, find last summer's best catch, and see your season in numbers with Pro.
02 — On your wrist, depending on your gear
The watch at sea.
The logbook on land.
Start your dive with one tap on Apple Watch, keep your eyes on the water, and find everything on your iPhone when you get home.
Available measurements depend on your watch model and on Apple's permissions. SpearfishOS is a logbook, not a dive computer. Details in the FAQ.
On compatible watchesDepth and durations recorded within the range Apple allows. The exact range is shown in the app.
On every watchA simple dive timer, readable at a glance.
Back on landThe dive lands on your iPhone. All that is left is to add the photos and the story.

Answers before you get in the water
Simply put, where are we?
How can I join the tests?
Write to hanif1@hotmail.fr. We will tell you when a build is available and which devices are supported. A request does not guarantee an immediate invitation. Beta versions are installed through TestFlight once a build is available.
Is it already a spearfishing social network?
Sharing with friends and compatibility with other brands are part of the project's vision. The current version is a personal logbook: no social feed or Garmin import is announced as available.
Can other people see my spots?
The logbook is local and private. Coordinates are excluded from exports by default. If you choose to share an export that includes coordinates, you control that sharing and should check its content.
Can I use the app without a subscription?
Yes, within the Discovery limits listed above. Pro extends the logbook; it does not unlock any Apple hardware permission.
Which watches are compatible?
The app targets watchOS 10 or later. The dive timer works on every compatible watch. Depth depends on the model and on the permissions granted by Apple: the exact range is shown in the app. Access down to 40 m has not been granted to SpearfishOS yet, and a subscription does not unlock any sensor. GPS does not work underwater.
Does the app replace a safety instrument?
No. It does not compute decompression and does not tell you when it is safe to dive again. Durations are for information only. Respect the limits of your equipment and the supervision rules that apply to your activity.
