Food APP

I started thinking about designing an app with food features that could be used to intelligently control kitchen equipment.
Yes, it should have an appetite, it needs a large area of white, plus an attractive yellow. It must look clean.
I designed some elements in the interface that I haven't seen in popular apps, such as the menu bar, which is like a long bread. There is also the avatar part of the personal center, and I made the background a chopping block.
These shapes look very different, but why are we exactly the same?
