Sky Safari 5
 
Ambitious stargazers are certainly familiar with the apps of Simulation Curriculum Corporation. The application titled "SkySafari" has been an integral part of astronomy apps in the app stores for quite some time. With SkySafari 5, the creators have reworked their app and upgraded it with a number of new products. Among other things, hobby astronomers now find in the area "Tonight" all the sunrise times and locations of the sun, moon, planets and the ISS space station. For the latter and other satellites, the application now also includes a notification option that tells when the objects are moving across the user. If you want to leave the earth's surface and fly through our solar system, you can also unlock the orbit mode via in-app purchase (1.09 Euro).

A more extensive database of all previously known planets, stars and other celestial bodies as well as support for controlling telescopes can be found, to varying degrees, in the app's Plus and Pro variants.
