Canvas Xcode Prototype
This one is an Xcode Prototype. Basically, a simple way to create animations in iOS apps. But still, it’s a coding-thingie that you may want to skip if you’re only interested in the usual design freebies.
Helpful hint: Dribbble users are nice. If the license is unknown, it is usually because they forgot to mention it explicitly; not because they were being stingy. Ask nicely and they will probably allow you to use it.
