Ionic 6 app on ios 30mb, why so large?

Hi, I m working on my personal app (ionic - angular), I m curious why my application is very large in size when build and installed in ios (30mb).
My bundle size was 1.2mb and I reduces it to 940kb now. but no effect on installed size in ios.

please help me, it is a simple application, and nothing is too complicated.
I have seen other apps installed on my iphone, they are hardly 10mb.
