I want to make "responsive screen" in my app

Hello, I applied pro account. Then I published web app and found that “if web app is opened in smartphone that small screen, All of component (button, white frame, etc.) and screen will not displayed correctly such as button shift, screen didn’t full display.” I understand that it’s not responsive web app
.
I want to know that if I publish my apps to apple store, will this problem happen again??
.
This is app’s detail :

  1. every conpoments is set resize mode in “float in place” except logo picture white frame in home screen and all component in search screen.
  2. In position screen I add picture in picture component. It’s not backgound
