Southern Stars offers three versions of SkySafari that differ in the size of their database, and in their selection of features. All three versions require Android OS version 2.2 or later, and run on Android tablets as well as phones. SkySafari uses standard Google Play licensing. You can install it on as many Android Devices as you have linked to your Google Play account. SkySafari requires a Google Play account, and will not run on devices (like the Kindle Fire) which do not have Google Play access.
The table below lists the main differences between the three versions of SkySafari.
