Intuitive

Sparrow is easy to learn. All developers that have come in touch with ActionScript, .Net or Java will  get started quickly. Especially Flash/Flex developers will feel at home immediately, since it follows most of the ActionScript dogmas and brings them to pure Objective-C.

Lightweight

Sparrow is a lightweight bird in many ways. We tried to keep the amount of classes and code down to the bare minimum (less than 10k lines of code). There are no external dependencies besides OpenGL, OpenAL and the standard iPhone libraries. This keeps your applications small and your workflow simple.

Fast

Sparrow is fast. It has been developed in parallel with two real life iPhone games (Twins & PenguFlip) and lots of performance improvements have made their way into the Sparrow core code. We are currently able to display and animate several hundred textured quads at 60 fps on the iPhone.

Free

Sparrow is free and alive. Licensed under the Simplified BSD license, you can use it freely even in commercial applications. We are working on it every day and we count on an active community to improve it even more.
