What applications can be created?

Question

Python

I have such a question, what applications / games can be created for android on python? I mean in terms of complexity. For example, is it possible to create an application that will monitor the state of the phone. Watch the battery, whether the phone is charging, check the memory for garbage. Is it possible to create a widget that will be on top of all windows? Is it possible to create an alarm clock? I just want to understand how complex applications / games can be created in python for android.

And one more question. Is it possible to change the design of the application? Create your own design of buttons, input fields, etc. Or is everything standard?
