How to reduce app size

Hi, When I am building my game with Unity for IOS the size of generated app was above 200mb initially. After compressing some textures I was able to reduce the app size to 108.3 mb but it is affecting the quality of images. The same project when build for android generated 38 mb apk.

I have also tried , Target device : IPad only, Target Platform : armv7, Api Compatibility level: .Net 2.0 Subset, Stripping Level : Use micro mscorlib, Script call optimization : Fast But no Exception,

Build Configuration : Release,

But the app size didn't reduce beyond 90 mb.

What else should be done to reduce the app size?

Mentioned below is the app size description in Editor.log. I have also described the original file size for some textures in brackets.

Textures 80.4 mb 87.5% , Meshes 2.9 kb 0.0% , Animations 1.0 kb 0.0% , Sounds 6.9 mb 7.5% , Shaders 0.0 kb 0.0% , Other Assets 30.2 kb 0.0% , Levels 307.3 kb 0.3% , Scripts 274.9 kb 0.3% , Included DLLs 3.8 mb 4.1% , File headers 205.9 kb 0.2% , Complete size 91.9 mb 100.0% ,
