About this app

Choose a square, assign colors round by round, and plan bags, blankets, and custom projects. The app automatically estimates yarn usage based on your hook size and gives you a clear project summary.

What you can do:
– Browse square categories: classic, solid, flower, mitered, circle, other, seasonal
– Mix & match designs and color combinations, save and compare ideas
– Export a personal PDF crochet guide anytime

Terminology & units:
Written instructions and diagrams are available in: SK, CZ, UK, US, DE, FR, ES, IT, PL, HU
Metric and imperial units supported.

They fixed the weird pricing issue but you can still only access the bog standard, easiest to do granny square unless you pay, which I will not be doing.

Thank you for the update — I’m glad the pricing is fixed. 😊 I understand and respect your decision. Just to clarify: the free classic square is there so you can try the app’s core features before subscribing. Wishing you happy crocheting!

Nothing you can't get free on YouTube or Internet search. too expensive to unlock. I am aware it is not a tutorial app. but still no more information given that I can't find in other places free.

Thank you for updating your review 😊 My goal is to help crocheters keep all their squares in one place and actually plan projects with them. I’m building this as a solo crochet maker. I keep the app ad-free, so subscriptions are simply what makes new squares and updates possible.

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.

Hi Kim, I'm really sorry for the trouble. The app is official and safe and only uses your email to create an account. It seems the confirmation email failed, possibly on Android 16 Beta. Please email us at support@grannysquaredesigner.com so we can help you finish signup or delete your data.
