BendLine Rope Studio
BendLine Rope Studio
BendLine Rope Studio is an offline knot-craft reference and calculation tool for sailors, climbers, arborists, scouts leaders, and riggers who need to pick the right knot fast, see exactly how to tie it, and know its real working load. Instead of a static picture library, the app simulates rope paths on a Canvas-drawn stage, lets users compare knots side by side, computes working load limits from seeded material tables, and lets people build named knot kits for specific activities — all fully local with no accounts, no cloud sync, and no personal data collected.
