On The Fly
A hand-drawn beat-map sketched on a paper napkin: the river flows diagonally across the artefact through a riffle, pool, and run, taking one named Mill Bend. Hand-lettered annotations call out the tree line, hatch zone (mayfly, September to April), the fishable bank, the out-of-bounds bank, wading depth over 0.6m after rain, and the rule 'Two rods at a time, by booking only.' A signed bottom margin reads 'Built for the people who keep flyfishing clubs alive.' followed by the handwritten On The Fly wordmark. The napkin rests on a worn wooden table beside a single coffee-cup ring.

On The Fly is a booking and management platform built for flyfishing clubs. Members book beats, accommodation, and other club resources from their phone. Committees run the whole club (memberships, waters, permits, pricing) from one place, instead of a stack of spreadsheets. Post-booking feedback turns every session's hard-won local knowledge into data the club can act on.

Free for clubs. We earn 5% only when bookings happen.

  • For your committee

    One place to run memberships, waters, beats, accommodation, permits, and pricing, instead of three spreadsheets, a Word document, and a phone queue.

  • For your members

    Book a beat, a cabin, or anything else your club offers, from a phone, with cancellation rules set by your club and shown at the moment of booking, not buried in a PDF.

  • For your waters

    Catch and water-condition feedback comes back from every booking, so the committee finally has real data to manage the waters with.

Full pricing and refund details on the Pricing and Refunds pages.

From the founder

Edrean Ernst, founder of On The Fly.

I'm Edrean Ernst, a keen but relatively novice flyfisher, and a software engineer with thirty years of experience.

I built On The Fly because I watched my home club's committee spend more weekends wrangling spreadsheets and chasing bookings on the phone than they did on the water. The tools they had didn't fit how a flyfishing club actually runs. So I'm building one that does.

I'm not the most experienced angler at my club. But I've spent thirty years solving problems with software. On The Fly is what happens when those two things meet.
