Four taps. The rest fills itself in.

  • Weather conditions imported automatically

  • Import from your smart watch (if you have it)

Logging a session for fun in OceanLog: pick your sport, spot, time and board, add a note, save
Read it back

Your sessions, arranged so they make sense.

Your watch data, read back to you and your coach in plain terms — what the sea was doing, what the weather did, and how the board and suit you chose suited you and the day. Not a score. An understanding of what happened, so the next session can be better.

Your coach, in the loop

They walk in already knowing.

Share what you choose, with as many coaches as you like, and take it back in a tap. Secret spots stay redacted — even from them.

How it started: SURF Log v1.9, a Google Form, after years of paper
How it started — a Google Form, after years of paper and kept notes.
Easy and secure

Log it, sync it, keep it.

Start fresh or bring over the log you already keep. Everything syncs across your devices, backs up on its own, and works offline for the trips with no signal — under the strictest European data protection rules.

What that means, in plain words →

Why it exists
“The tools either forecast the ocean or count your waves. None helped me understand the session I'd just had — so I made the one I wanted.”
