    Hi to all!

    I have experienced something weird with regards to the size of apps: when I plug my iPhone/iPad, in the App panel, I see that some apps are very large, for instance, Dead Space HD is ~800Mo.
    When I click on an app in iTunes, it is also 800Mo .
    Then, I unplug my iPad, close iTunes and open it again, and when I look at Dead Space HD, it is around ~400Mo, the size it should be.
    Has anyone experienced something like this?
    And, more importantly, what's the actual size of the app in my iPad?
    I am feeling a bit cramped on my 32Go iPad and I am wondering whether it might be related to this.

    Thanks!

    The .ipa files (the file for installing the app on your iPhone) is smaller than the installed app on your iPhone.

    So if your iPhone isn't connected, iTunes shows the size of the .ipa file (400mb). When your device is plugged in, it shows the size after installing (800mb).

    The .ipa files are .zip files, just renamed.
