Unity build Complete size does not match app size

Hello,

Scrolling through the logs trying to comprehend why in the Unity log it tells me "30.6mb"

but if I go to app info (on iOS build) to see how many mbs the game is, it in fact says its: 99.9mb

now that is a significant difference and I cannot afford the additional MB's on mobile phone !

Can someone please explain to me or point out why this is happening, am I doing something wrong or ??

I really will appreciate the help on this, here is a copy paste from Unity's log:
