Karuk

Karuk turns your colour ideas into friendship bracelets you can actually tie. Draw the palette you want onto a diamond knot grid and watch the on-device solver work out every knot in real time — no guessing, no counting threads by hand. Start with the paint-and-solve board: tap a diamond, pick a colour, and Karuk figures out whether that spot needs a forward, backward, forward-backward, or backward-forward knot. Unreachable nodes are flagged instantly so you can swap in a reachable colour or let the auto-fix resolve every conflict at once. The string-order finder tests dozens of starting arrangements and ranks the top three by conflict count, so you can pick the layout that works best before you cut a single thread. When your pattern is ready, Tie-Along walks you row by row through the actual knotting: a zoomed three-row window keeps the current knot in focus, and plain-English instructions name the thread and knot for every step. The thread-length calculator takes your wrist size and thread type, then outputs exact cut lengths for every string based on the knots you will actually tie, including a copyable cut list. The thread stash tracks what you own by the metre, tells you whether you have enough for any pattern, and generates a shopping list you can mark as bought. Browse 90 built-in patterns — 60 classic designs across twelve knot families, plus 30 hand-drawn pixel pictures — or build from a photo using the colour-matching starter. Eight auto-generated variations (mirror, colour rotation, direction flip, and more) let you explore alternatives without starting over. Practice knots on the two-string bench or take a twelve-round identification challenge to sharpen your technique. Share any pattern as a rendered sheet or a compact code a friend can import directly into their own copy of Karuk.
