Freebbble!

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.

Canvas Xcode Prototype is a free Various design resource made by Dribbble user Meng To. As far as I can tell, its license is Free for Commercial and Personal Purposes.

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.
