Jupiter Simulator is an astronomy app that shows the location of the four largest Jupiter moons and their shadows, and the Great Red Spot.
All positions can be shown in real time, or in faster animation. You can set the clock to other times in the future or past.
You can navigate in three dimensions, and zoom in and out. The orbits of the moons can be made visible.
