Huge size difference between Unity build for Android(38mb) and IOS Xcode Estimate app size (135mb)

Hi,

Recently I am working on a 2d project.I had finished it ,and took a build for android and got an apk for 38mb. Later I moved over to IOS platform.I did all the necessary changes, and even made those texture to the worst quality like 16 bits and those POT textures and sprites as compressed(as my aim was to get the build size to the very least) and got my build to around 135 mb,when ever I archive it in Xcode and ask for estimated size.I tried all ways and my resource folder too has only 2 text files.I would like to know the reason,if my build settings are wrong or some options should be enabled in Xcode side.I have searched all forums and tried all those methods mentioned ,but none of them actually worked

Note-Please don’t mind the lack in technical details and do let me know if more information is needed,I am just a beginner in programming don’t mind the vagueness .

The .apk is compressed

The XCode estimate is now an uncompressed size (larger than the .ipa size)

Hi,thanks for the reply.Your right.I saw this Ipa file coming around the same size as android.So this the file which will go to IOS store right?Because the size now is around same as android APK,and happy with that.Sorry again for my very silly questions,I am completely new to this.:frowning:

I’m running into a similar issue.

iTunesConnect estimates my download size as 77mb and an install size of 158mb.

On iPad the app is 160mb, so really close to the estimated size.

However, the Android .apk is 60mb and the Android Tablet’s internal storage is showing around 79mb.

I use compressed atlases for all my textures so there shouldn’t be a big disparity between platforms.

So, right now, the iOS app is DOUBLE the Android app size on device. Does anyone know why?
