Every session
counts.
Every session becomes a visible journey—and one more reason to paddle out. Apple Watch and Garmin can both record, bringing your waves, tracks, and effort back to iPhone as part of the same journey.
Use Apple Watch with iPhone, or Garmin with iPhone or Android.

FEATURED STORYFeatured by [Si]gnals
A surfer builds an app at sea—using data to ride the next wave
How real constraints from wet hands and Water Lock shaped SurfBound through AI-assisted development and iteration on an actual Apple Watch.
Article in Traditional ChineseONE TAP. THE REST IS OCEAN.
Automatic tracking.
Verified by you.
Mark the ride with one press
On Apple Watch Ultra, use the Action button after a ride—or once you paddle back to the lineup—to leave a wave marker.
Progress every time
Each session builds your journey and spot footprint through hours, milestones, and progress at the breaks you return to.
Your data is yours
Recording needs no registration; only Lineup requires Sign in with Apple. No ads or selling data. You decide whether to share test data.
HUMAN-VERIFIED WAVES
More than a wave count
you have to trust blindly.
GPS and wrist signals in the ocean will never be perfect. SurfBound lets you review waves counted by mistake or missed entirely, turning automatic detection into a session you can trust. The full workflow stays inside the iPhone tutorial—we do not publish the labeling details on the web.
01YOUR SESSION
You confirm what happened
The app records automatically. You decide which waves truly belong to the session.
02OPTIONAL
Sharing is your choice
Corrections help detection only when you enable test-data sharing. No new data is uploaded after you turn it off.
03THE GOAL
Smarter on your Watch
Our long-term goal is an accurate edge AI model that runs directly on Apple Watch.
Shared records are associated with an iCloud identifier but contain no name or email, and are used only to improve wave detection.
