Which Chipmunk to get?

[snorf]

I am looking to do development on a 2d game for iOS using the chipmunk engine, but the Chipmunk Pro page of the site confused me.

It has a section called "What do you need to buy" and it says that to do iOS development you should get Chipmunk Pro. However the chart below leads me to believe I would be fine using Chipmunk Indie. Which version is right for me?

I think you might be confused about Objective-Chipmunk, the Objective-C binding that comes with Pro. It's not required to be able to develop on iOS, it just makes Chipmunk fit in better on iOS.

Chipmunk is written in C and runs on pretty much anything. It's open source and free.

Chipmunk Pro has some specific optimizations for ARM and multi-core platforms, a library for generating collision geometry from image or procedural data, and an (iOS/OS X only) Objective-C binding. The Objective-C binding makes it much easier to do iPhone development (integrates easily with Objective-C APIs and memory management including ARC), but you can certainly do just fine without it.

Chipmunk Indie is cheaper and contains just the Objective-C binding if you don't care about the extra performance (Chipmunk is already quite fast), and don't want to use the automatic geometry library.

Chipmunk Studio and Enterprise and geared towards larger companies and include more support and license options.
