Difference in download size and installation size

Hi, can someone explain me why there is so huge difference between download and install size? I get it that download is compressed but there difference is really huge.

Some types of resources in an app compress really well. If you run unzip -lv /Path/To/YourApp.ipa in Terminal, you can get an idea of the compression ratios for files inside your app.
