Delta-v/TWR/Acceleration calculator if anyone wants one

[phg0002]

I have made this calculator and would like some feedback on it. It calculates Delta-v, thrust to weight, acceleration, and time at a current stage it would take to reach escape velocity. It takes into consideration differing surface gravities and atmospheric pressures.

It is 934KB and does not require installation.

You need dotnet 4 or higher to use this program. It was made in C#.

I'm planning on making an android and iOS version, but I want to get some input first.

I think the math was pretty solid, but let me know what you guys think.
