Android car power gauge

I want nice looking GUI for application based on physics, computing and math. With data from accelerator I am able to compute the car horsepower. I need 1 entry field for car mass, 3 Buttons (Start, Stop, Reset) one gauge and 2D graph (time vs. HP). All I want to have on main screen with ability to save graphs with axes on PNG file. In application I need one function that is called exactly every 1 or 10ms (for example) and interface to easily handle and write data, eg prepared functions (I know some JAVA but not android engine). The basis (intel) of application will be written by myself, you may understand the security reason.
