Rymaro is the complete knot-tying companion for outdoor enthusiasts, climbers, sailors, and anyone who works with rope. Browse a catalog of 42 essential knots across six categories — Loop, Bend, Hitch, Stopper, Binding, and Lashing — and master each one through interactive, step-by-step animated guides right on your device.
Follow the built-in StepBuilder to tie any knot at your own pace. Each step renders a precise rope diagram so you can see exactly how the rope crosses and wraps, making it easy to learn complex techniques like the double fisherman's bend, prusik, or figure-8 loop without outside help. When you complete a knot, mark it learned and watch your progress rings fill in across every category.
The Rope Lab lets you explore six real rope materials — Nylon, Polyester, Manila, Polypropylene, Dyneema, and Cotton — and see how diameter, applied load, and wet conditions affect holding strength, slip risk, and jam risk for any knot. The Load Simulator visualizes tension as particles flow along the rope path in real time, giving you an intuitive feel for which segments bear the most strain under pressure.
Track your journey in the Practice section: per-category mastery rings, a drill log, free-text notes, and a photo diary keep your progress organized and motivating. Whether you are preparing for a camping trip, rigging a boat, or simply building a new skill, Rymaro puts every technique you need in the palm of your hand.
Note: All hold, slip, and jam figures in this app are estimates for learning about knot mechanics — not certified test data. Never use this app for life-safety rigging decisions.
