Icarus Rocket Calculator provides a useful reference tool and automatic calculator for eleven of the most common equations used in rocket science.

The program displays the equations for: DeltaV, Effective Exhaust Velocity, Specific Impulse, Gravity Losses, Drag, Burn Time, Burn Rate, Propellant Mass Fraction, Dynamic Pressure, Acceleration, and Thrust to Weight Ratio.

This app is extremely easy to use. The main screen provides a scrollable list of all of the equations, tapping one will bring you to the display for that equation.

This will allow you to view the equation, and enter the values needed to calculate it. When all required values have been calculated, the result will be displayed.

To go back to the main screen, simply use your devices back button.

A much more in depth document detailing the equations used in this app, as well and many more, can be found here:
