How it measures
Your catch, measured in seconds.
Measure uses your iPhone camera to trace your fish from nose to tail and gives you an estimated length on the spot. Not quite right? Drag the end points to fine-tune it.
How it works
Three steps, no tape required.
From fish on the ground to length in your catch log in under 10 seconds.
Lay it flat
Place your fish side-on on a flat surface: the ground, a board or the deck. Not in your hands.
Frame it from above
Open Tackle Box → Measure, hold your iPhone over the fish and line it up with the outline.
Tap Measure
Get the length in seconds. Drag the end points to fine-tune, then tap Add to Catch.

Pro tip
Lay it flat, not in your hands.
A fish held up for the camera is angled and partly hidden by your fingers, so the length comes out wrong. Lay it flat and shoot straight down from above for the best result.
Good to know: Measure is available on iPhone only. Lengths are estimates and can be affected by angle, light and distance. Where legal size limits apply, always confirm with a ruler or tape before you keep a fish.
