I’m use unity iphone build game app,this app just had 2 lines code,but created the .app file have 29M,How can i make the app to small?

The .app size is not the size that it will be on the App Store. Do a search of the forums and you should find mine or someone else’s description of how to estimate the size. It is possible to get under the 20MB 3G download limit.

Unity has a base amount it needs. This can be reduced with stripping if you have Unity Pro. You can also reduce size if you build for armv6 or armv7 only, not both. armv7 is probably the best option as it is likely to become the only option with iOS5. Release size will also be smaller than Debug.

It won’t appear quite that big when it’s all zipped up, but essentially the unity engine requires about 15mb (non-pro) and 8mb (pro, with byte-code stripping).

^ Moonjump got there first - with a better answer :smiley:
