Inari Mobile Technologies has produced a dope app called "Kicktionary," which provides some biography on classic, new releases, and limited shoes. Right now there are around 200 shoes sectioned into categories which include: Basketball, Jordan, Running, etc. that are archived in the app - which are all nike as of now. The app is going to be constantly updated with new releases x classics, which will include a variety of brands added to the list.
The app is on sale for $1 for a limited time during the summer in the app-store. Downloading the app took a good minute, I would definitely download it directly through itunes, then installing it on your iphone.
