KnotStep: Tie Any Knot
Step-by-step knot guide
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Tie the right knot for the job, even with no signal.
KnotStep is a calm, illustrated guide to 44 knots that matter on the water, on the rock, and at camp. Every knot has clear numbered steps, a hand-drawn diagram for each step, a holding-strength rating, a plain use-it-for line, and an honest watch-out note so you know its limits.
Grouped by what you are doing:
- Fishing: line to hook, line to line, and reel knots like the Palomar, Improved Clinch, and Blood Knot.
- Boating: the Bowline, Cleat Hitch, Clove Hitch, Anchor Bend, and more.
- Climbing: the Figure Eight tie in, Double Fisherman's, Prusik, and other essentials.
- Camp: the Taut-Line Hitch, Trucker's Hitch, lashings, and quick releases.
What you can do:
- Follow step-by-step instructions with a diagram drawn for every move.
- See each knot's holding strength, difficulty, use, and safety note.
- Search by name or by purpose, like anchor, loop, or join.
- Save the knots you actually use to your kit, then see your kit's average holding strength and a by-use breakdown.
- Compare every knot for a job, ranked by holding strength, so you can pick the strongest or the easiest strong option.
- Export a printable Kit Card PDF or a CSV of your saved knots, for the dry bag or the glovebox.
Built to work anywhere:
- Fully offline. No account, no cloud, no tracking.
- Everything stays on your iPhone.
Free and Pro:
- Free includes the 12 starter knots, three per use, full search, and a starter kit of favorites.
- A single one-time purchase unlocks the full 44-knot library, unlimited favorites, and the printable Kit Card PDF and CSV export. No subscription.
Knots used for climbing and rescue carry real risk. KnotStep is a reference and learning tool. Learn from a qualified instructor and always have a partner check safety-critical knots.
Ratings & Reviews
Every knot is redrawn. All 44 knots now have their own step by step diagrams that show the real rope at every stage, with over and under crossings you can actually follow, instead of generic shared figures. Instructions and use notes were checked against authoritative references and corrected. Plus a brand new app icon.
