This app is written for space and spacecraft engineers. Taking its cue from a calculator app, it then expands that to add in specific altitude- or radius-based calculations for items of interest.

The calculator value in the screen with a single button press is accepted as input as either a radius value or as an altitude value for calculation of the orbit-related values of interest.

So, its a fully featured calculator for mission analysis!
