About Night Sky
Night Sky identifies stars, planets, constellations and satellites, with sky maps and guided tours. Its Aura astronomy assistant and Aura tours need a Night Sky + Aura subscription.
Version 27.1 is optimized for iPhone Duo, the release notes say, and gives the Aura Tonight Tour its own layout for when you sit down with the phone. They don’t describe how the tour and its controls are arranged.
