Hookchart: Crochet Charts

Design professional crochet charts on your phone or tablet. Hookchart is a dedicated pattern editor with a feature no other app offers: rotate every stitch symbol to any angle, freely. Build diagrams the way you actually want to read them.

CORE FEATURES
• Square and round (radial) grids
• 8 standard stitch symbols: chain, slip stitch, single crochet, half double crochet, double crochet, treble, magic ring, cluster
• Per-symbol rotation — any angle, not just 90°
• Smooth pan and zoom
• PNG and PDF export
• Unlimited projects — save, reopen, duplicate

DESIGNED FOR TABLETS
Hookchart is built with 7–10" tablets as the primary target. The canvas is sized for precise symbol placement with a stylus or finger. Phone layouts work too.

OFFLINE AND PRIVATE
Everything runs on your device. No accounts, no signup, no cloud. Airplane mode is fully supported. Your patterns stay yours.

FREE — NO PRO TIER, NO SUBSCRIPTIONS
Every feature is free. The app is supported by a single banner ad on the home screen and an optional rewarded ad before exporting. No ads inside the editor. No feature locks.

WHO IT'S FOR
Intermediate and advanced crocheters who design their own patterns, teachers preparing tutorial diagrams, and designers publishing their work. If you've ever fought with a generic diagramming tool to draw a crochet chart, Hookchart is built for you.

EXPORT
• PNG for web, social, and print
• PDF for publication-ready patterns

Stitch symbol conventions follow the widely-used Craft Yarn Council standard; the artwork in this app is original.
