Ratings and reviews

Absolutely brilliant app for crocheters using granny squares in their projects. It's everything I was looking for to create a template for a granny square cardigan. Super user friendly and very handy! Initially I had some issues but the team was super helpful and everything is sorted out now. Very happy user!

barley let's you do anything without paying you only get 1 free granny square youre not allowed to do anymore after that and it limits all other design choices other than the basic one and you have to register and go through a whole signing up process before you get to do anything also has wayy to many ad's and i had to have the confirmation email sent to me three times before it let me sign up

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.

What’s new

Bug fixes and small improvements. Added an optional in-app rating prompt.
