When you develop iOS apps with an OpenGL framework such as Cocos2D you will quickly find out that memory is a scarce resource on mobile devices. One useful way to save memory is to use so called sprite sheets that bundle images into a single file and provide textures directly.

A complete tool that makes it easy to create and manage sprite sheets is TexturePacker. Its basic features are free and the pro version costs 19.95$.

I used TexturePacker for my app Snakestein’s Reading Game. You can check out the result in the free or full version on the App Store.

There are great posts by Ray Wenderlich and Chris Fletcher on how to use TexturePacker.
