Where do you see 3mb? I see "4.3 MB" on the App Store page but still that's impressive.

When an app is uploaded to the app store, it is compiled for every different device separately. You likely have a higher resolution phone/device than the OP, so there's more image data on your version

Not sure what causes this.
