Three drills

Feel the rhythm, not just the angle.

Hold your phone like a rod and Driftline reads your motion with the iPhone's built-in sensors — coaching the parts of fly casting that are hard to practice on dry land.

Cast — 10 & 2

Nail the classic overhead stroke. Driftline grades each stop as crisp, soft, or mushy and warns when you break the wrist past your target. Adjustable angles and a metronome for tempo.

Mend

Track the drifting fly down the river and flick your mend in the 12-to-2 o'clock window. A bigger, stronger mend buys more drift — just like on the water.

Dry the Fly

Quick, crisp false casts whisk the water off your fly. Watch the bead shrink and fling droplets with each stroke, then a chime when it's dry.

A look inside

Coaching you can see and feel.

Clean, focused screens for each drill — with live audio and haptic feedback as you move.
