Photograph the bug. Tie on what matches.
Before the rise is over.

10 free identifications to start.

Built for anglers who turn over rocks. And the ones who didn't know you could.

Identify

Point at the insect. The app names it, and shows how sure the answer is.

Match

Works on artificial flies too. Hatch, species, pattern, and confidence.

Rivers

Flow, forecast, and water temp for any gauged river in the lower 48. Premium NorCal rivers add the hatch's hot flies and a guide's report. (More rivers coming soon.)

Flybox

Every identification goes in your digital flybox. The more you identify, the smarter it gets.
