User reviews

Users praise Celestia for its educational value, stunning graphics, and extensive astronomical content resembling PC space simulators. However, many mention the app's large storage requirement without SD card support, control and interface challenges, occasional performance glitches and crashes, and incomplete features like missing procedural stars or planet textures. Overall, it is regarded as a high-quality space exploration app but with room for improvement in usability and content completeness.

Pros

Excellent educational and exploration tool for learning about galaxies, exoplanets, and other celestial bodies.
High-quality graphics and realistic space simulation that rivals PC applications like Space Engine.
Offline functionality with impressive graphics on mobile devices.
Wide range of add-ons providing detailed astronomical features including nebulae, black holes, and planets.
Low to no ads, making for a pleasant user experience without interruptions.

Cons

Large app size and storage usage, with no option to move the app to SD card on mobile devices, causing issues for users with limited storage.
Controls are sometimes hard to manage with issues such as pinch-to-zoom triggering context menus unintentionally.
Incomplete or unrealistic representations of some celestial objects, including blank textures on planets and lack of procedural stars.
Performance issues including lag, occasional crashes, and glitches especially when near black holes or after installing add-ons.
Limited procedural generation, missing features like black holes on some versions, and inability to freely fly in space without interacting with objects.
