Karuk

Ever sketched the friendship bracelet you wanted, then got stuck working out which knots actually make it? Karuk works it out for you. Paint the colours you want onto a diamond grid, and a knot solver follows every thread through every row to tell you the exact knot for each diamond: forward, backward, forward-backward or backward-forward. What it does: - Checks the design as you paint. If a diamond asks for a colour no thread can bring there, it's circled, and one tap 👆 swaps in a colour that works. - Tries dozens of starting thread orders and shows the ones that make your design tieable, plus whether it repeats without a seam. - Draws a knot map 🗺️ with each thread's path, then walks you through tying one knot at a time ⏱️ ("Rust over Lagoon, forward-backward"), saving your place. - Calculates how long to cut each thread from the knots it really ties, for your wrist size and thread type ⌨️. - Picture (alpha) patterns with a row-by-row plan 🗺️ for the working thread, and an optional photo 📸-to-grid starter. - Eight generated variations of any pattern 🔢, one of them using only the colours in your stash. - A thread stash that tells you what's missing before you start 🚀, plus a shopping list 📋. - A gallery 🖼️ of 90 patterns to copy and change, a knot practice 🏋️ bench, and export 📤 as a pattern 🔢 sheet image or a short code a friend can import. Karuk is for anyone who knots bracelets, from a first four-thread stripe to a sixteen-thread chevron. Everything runs on your phone 📱, with no account needed. Tape your threads down, open Karuk and tie the first knot.
