Pttrns is a curated library of iPhone and iPad user interface patterns. All patterns has been carefully chosen before they were added to maintain excellent content quality. There is currently 2764 patterns in our library. I started this project in Prague, February '11. The site is currently doing almost 2 millions page views per month.
In the beginning, it was just meant to be a personal and private tool for my own inspiration. I was always measuring dimensions between various objects in the native iOS interface and didn't want to make screenshots everytime I needed it and so the idea for Pttrns came along.
