A free open source wireframing app for iPad.
Website: wireframeapp.com
I will add here instructions on how creating your own renderers. Please, respect the license. (GPL!).
This project reflects me learning Objective-C and iOS at the same time, lots of unfixable mistakes made. But overral, the app is great.
Hope you like it.
