FAQ
Frequently asked questions
Is YarnCro free?
Yes — you can start free with 3 pattern builds per day and no credit card. The row counter, yarn stash, and yardage calculator are always free. Pro removes the limits at $5.99/month or $39.99/year with a 3-day free trial.
What can YarnCro make patterns for?
Describe any project — amigurumi, hats, blankets, garments, granny squares, bags — and YarnCro writes a full round-by-round pattern with materials, gauge, and finished size.
Are the stitch counts actually correct?
Yes. A deterministic code engine re-computes every round — increases, decreases, continuity, gauge — and rejects any pattern whose numbers don't add up, so it checks the math instead of guessing. Note: math-verified counts don't guarantee fit, so always crochet a gauge swatch first.
Can YarnCro identify a crochet stitch from a photo?
Yes. The Stitch Scanner identifies the stitch from a photo and gives a technique tutorial. Pro users can also reverse-engineer a full pattern from a photo of a finished item.
Does YarnCro support left-handed crochet and UK terms?
Yes, on Pro. Left-handed mode mirrors every instruction, and a UK/US terminology toggle switches all terms throughout the pattern.
Do I need to download an app?
No. YarnCro runs in any web browser and installs as a PWA — open yarncro.com and tap 'Add to Home Screen' to use it like a native app, no app store needed.
How much does YarnCro Pro cost?
$39.99 per year (about $3.33/month) or $5.99/month, with a 3-day free trial. Cancel anytime.
What languages does YarnCro support?
English, French, Spanish, German, and Italian.
