About this app
What Knotbench does
Every popular knot-tying iOS app uses photos or low-res GIFs. When you're on a boat with one hand on a line and one on the phone, low-res photos at a sketchy angle aren't enough. Knotbench animates every knot using SwiftUI Path drawings — vector-perfect at every zoom level, infinitely smooth. Pinch to zoom, drag to rotate, tap to step through the tie. 30+ knots organized by use: — Boating: bowline, cleat hitch, clove hitch, round turn + two half hitches, anchor hitch, sheet bend. — Climbing: figure-eight follow-through, double fisherman's, prusik, clove hitch on carabiner, alpine butterfly. — Fishing: improved clinch, palomar, uni knot, blood knot, double surgeon's loop. — Household: square (reef) knot, taut-line hitch, trucker's hitch, double half hitch. — Decorative: monkey's fist, turk's head (3 lead 4 bight), lanyard knot. Each knot includes: — Animated step-by-step tie — When to use / strength / failure mode — Common mistakes — Practice timer ('tie a bowline in under 10 seconds') No account. No subscription. No internet. Ships fully offline because cell signal at the dock is bad and yours might be too.

Why it exists
The problem
Existing knot apps use static photos or pixelated GIFs that fail at boat-rail viewing distance. Top app on the store (Animated Knots by Grog) uses video which needs to buffer and is hard to scrub. No app uses vector animation for crisp zoom.
What's different
How Knotbench stands out
Knotbench is the only iOS knot reference where every knot is drawn natively in SwiftUI Path — vector-perfect at any zoom, with step controls (tap to advance, swipe to scrub). 30+ knots span boating/climbing/fishing/household/decorative categories. Practice timers, failure-mode notes, no subscription, fully offline.
