– Export a personal PDF crochet guide anytime

Ratings and reviews

Cannot register. I tried two different email addresses and never received the email required to finish registration (and yes, I checked my spam folder multiple times). The registration process didn't ask for private info, but I'm now worried that just downloading this [possibly] fake app has compromised my phone.

A wonderful app! The only downside is a few granny square patterns are available without purchase. Nearly everything is locked behind a paywall, However the interface is very pleasing to look out and making a project is very easy!!

cool concept but I get one granny square after it taking a couple minutes to load then nothing else loads in the app. cant finish a project or anything.
