‘Satellite Explorer Pro’ is a tool for tracking satellites in real time. It is not a game. Be sure to visit the support web site http://www.tomdoyle.org/SatExpPro. The app is easy to use and has built in help which you should read before using the app. A simpler version of this program called ‘Satellite Explorer’ is also available in the app store.
The iPhone screenshot below shows the main program screen. The tracking map shows the current location as a red diamond and the satellite track as a series of blue dots. The dots are spaced apart equally in time. The satellite location is shown as a blue circle with a blue dot in the middle at the start of the track. The satellite coverage circle is shown as yellow circle
