Plan and capture every aspect of your fishing sessions.
Turns fragmented notes, photos and half-remembered swims into detailed catch reports. Improve your watercraft. The more you fish, the sharper it gets.

Everything you already keep in your head.
Sessions, catches, swims and weather — in one place, on your phone, getting sharper every trip.
Sessions, not just catches
Start a session, log every fish inside it. See exactly how long you waited between bites, and what changed when they came on.
AI species ID
Photograph the fish and Fish On names it. Snap, weigh, log — the whole record in under ten seconds.
Swim maps you actually use
Sketch the peg. Mark cast spots, snags, depths and standing positions. Next time you're back, your homework's done.
Personal bests, on autopilot
Every catch is checked against your best for that species. Beat it and the PB badge appears. No spreadsheet, no arguing with friends.
Pressure, bite windows, moon
48-hour pressure chart with dawn and dusk bite windows overlaid, a 10-day forecast and today's astronomy. Plan the session before you leave the house.
Built for the bank
Designed for one hand, in daylight, with wet fingers. Big taps, fast forms — logging never gets in the way of the next cast.
