Dear Community

Just discovered this today. I tried to check the app size. and I found the app downloaded from App Store used much less storage on disk then its actual size. Please see the screenshot, the actual app size is 180MB, but the size on disk is only 57MB. On the other hand, apps downloaded and installed manually use a little bit more storage on disk than its actual size. (51MB actual size, and 57MB on disk)

Can I ask how can I apply this app compression on the manually installed apps?

Thanks
