Whether you're on a boat deck, at a campsite, or halfway up a climbing wall, Knots 3D puts a knot-tying coach in your pocket. Download the Knots 3D IPA for iPhone and pull up any of 151 knots in full 3D, ready to rotate, zoom and step through at your own pace.

Arborists, anglers, firefighters, climbers, sailors and scouts all rely on this app to nail down knots that are easy to fumble from a flat diagram. Trace the rope with your finger to tie and untie each knot, watch it draw itself automatically, or spin it around to see exactly how the line loops, crosses and locks.
