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 (around 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 the fastest bird in town. It has been developed in parallel with two real life iPhone games (Twins & PenguFlip) and lots of performance optimizations have made their way into the Sparrow core code. Display hundreds of animated quads at 60 frames per second!
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 our active community is constantly improving it even more.
