Great App!

I am so happy to have found this app, it's the magic wand for knitters. It has the formulas for shaping: shoulders, arms, front body and back. Plus the gauge formula. Easy to use!!! 5 stars for sure.

So happy to have this when my brain is just too tired to calculate. Awesome idea. Anything else coming soon?

Knitters toolkit

I used Amy Hetzogs app before & it was excellent. This thing is horrible! It wouldn’t allow typing in the values for the button band before jumping to instructions.
