SunChaser

In a nutshell, this is an app that calculates sunrise, or sunset for a moving vehicle. Primary use would be for pilots in aircraft, secondary use for long road trips.

In GPS mode, the app uses the vehicles position, speed, direction, and altitude to find a point in the future when the vehicle will encounter sunrise or sunset.

In Manual mode, the user sets the location, speed, direction, and altitude and gets the point where sunrise will be encountered.

I mainly made this because I was tired of other pilots trying to predict when sunrise or sunset would happen.
