Maximum iPhone App Size?

Unity Engine
,

Hi,

I’ve recently launched a new Unity3d iPhone game, Tail Gunner, but whilst it appears to work ok on 3GS phones, I’m having problems with earlier devices specifically iPod Touch 2nd Gen. The crash reports are listed as LowMemory errors.

The app is about 63Mb in size - is this too large? The app seems to error in a number of levels, but only ever on level loading?

One thing that seems to make it crash constantly is having a skybox enabled. Does anyone else have this problem?

Any help is appreciated.

John,

you may want to take a look at this thread:

Hi Steve,

Thanks for that, I had actually found that thread already, but for me, even if I disable the skybox altogether, I can still get the app to crash due to low memory.

I guess my question should be in 2 bits:

  1. Is there a max recommended unity3d app size (i.e. 35Mb max)
  2. What is it that kills unity on the iPhone. Is it lots of small textured polygons, or a few very large textured polygons.

Any help from anyone is welcome.

Hi John,

I can’t see the size of the app being an issue in your case (could be wrong).

WRT performance then there are lots of threads on this. If you have not done so already then work through them.

Also look at using Instruments (again if you have not already done so) to see where the bottlenecks are.
