Your first session in thirty seconds

Most logbooks die on page two. The first session is exciting. By the third, you realize the form is too long, you can’t remember the swell direction, and the app won’t save until you’ve ticked a dozen things you don’t actually care about today.

Swellbook is built around the idea that the form should be shorter than the paddle out. Here’s what logging an actual session looks like.

The shortest possible version

Open a new session. Today’s date is already filled in. Save.

That’s a valid session. The app accepts it. It’s also useless — it’s a dot on the calendar with no context. But the form will let you do it, and that matters: the only required field is the date. Everything else is optional, including the things you’d assume were mandatory.

The version that’s actually a session

Three more taps and you’ve got something worth keeping:

1. The spot. Pick from a spot you’ve ridden before, or drop a new pin. The session attaches itself to the right place on the map.
2. The board. Pick from your quiver. If your quiver is empty, the first board you log becomes the first board in your quiver — the setup happens by using the app, not before it.
3. A note. One line is plenty. “Glassy at sunrise.” “Got the shoulder both ways.” “Lost a fin.”

Spot puts it on the map. Board puts it on the per-board day count. The note puts you back inside the day six months from now.

The version that becomes a memory

Add photos. Pull a couple from your library — Swellbook stores them itself, so they stay tied to the session even if your camera roll moves on. That’s the version most good days deserve. Still under a minute.

What you can skip forever

Swellbook has fields for conditions, wave size, wind, fins, wetsuit, water temp. They’re there for the people who want them. They’re empty by default and stay empty unless you fill them in.

A common mistake with logbooks is treating every field as a requirement. It isn’t. The form is short on purpose, and the optional part is short for a different reason: the days you remember are not the days you remembered to record the wind direction.

The first week

For the first week or so, log the sessions that matter. Not all of them, not perfectly. The one with the dawn glass-off. The trip where the swell was bigger than forecast. The day you finally surfed the spot you’d been driving past for a year.

After a week you’ll have five or six entries. The map will have started to fill in. Your quiver will have a couple of boards in it with day counts attached. The wishlist might already have ticked one item off on its own.

That’s the moment the app starts being interesting. Not on session one — on session six, when scrolling back is suddenly a thing you can do.

A common worry

People sometimes worry that a logbook is a commitment. This one isn’t. Skip a month, the app doesn’t notice. Skip a year, your data is exactly where you left it. Open it in February to plan a trip and the spots from last September are right there.

The whole thing is designed to survive the realistic version of how people actually use a surf app — sporadically, around the trips that mattered, with a long off-season in the middle.

The app is on the App Store. Free, iOS 17+. Start with the last good day. That’s the one to log first.
