In addition to the full PocketSat3 application, there is also a less expensive "LE" version available. It is identical to PocketSat3 except that it only works with a fixed set of 40 of the brightest satellites in the sky. These include the International Space Station, the Hubble Space Telescope, and the Space Shuttle (if it happens to be flying) so PocketSat3 LE is perfect for the neophyte or casual satellite observer who would still like to use a full-featured tool.
Note that as a consequence of the fact that the LE version does not load data for any Iridium commuications satellites, it cannot predict Iridium flare events.
