Fly Box Tally

Track stock after every outing

Fly Box Tally is an offline-first inventory for the flies you actually carry. Open the app and land on a river-slate grid of your own patterns—each tile shows name, hook size, colour chip, and how many are left in the box.On the water, tap a tile to decrement a used or lost fly. Miss-tap? Undo the last action. Group every change into a named outing session so stock updates when the trip ends—not when you guess later…
