Your source for handheld satellite tracking software since 1999.
PocketSat3 for Android! (also for iPhone, iPad, and iPod touch)
Have you ever looked up just after sunset or before sunrise and watched a steady light moving slowly across the night sky? It may well have been a man-made satellite, many of which are visible to the naked eye - if you know when and where to look.
PocketSat software allows you to predict when satellites will be visible in your location and where to look in the sky in order to see them.
