Using retina display Vs Binary size

Question

I'm currently updating my app's images to have a nice display on iphone4 with retina display. Everything works well and I'm quite happy with it.

However, what concerns me is that increasing binary size... (starting from 2Mb, I reached 4) Did you find a way to have nice images and to keep a decent size for your binaries?

Tips or advices would be welcome!

Answer 1

2 MBs more don't matter at all on a 32 GB device. 4 MB is 1/250th of a GB. :) (okay, it'd allow the user to sync a half MP3 less.)

I always delete non-retina apps. They suck and are ugly. If you don't care about uglyness, I'd suggest you quit iPhone development and start Windows Phone development (A)

Answer 2

It's sometimes worth running something like pngcrush on your image files. It should result in zero visible difference but often results in far smaller files.
