User Reviews

Celestia on iOS delivers a strong, Space Engine–like space exploration experience with solid visuals and useful add-ons, and it’s educational. However, reviewers repeatedly note content depth and breadth are limited (few galaxies and bodies), controls are awkward, occasional visual glitches occur, and there’s no way to create your own planets or solar systems. Addressing these issues would broaden exploration and improve usability.

Pros

Engaging space exploration experience that appeals to space fans.
High-quality graphics on mobile with a Space Engine-like feel.
Support for add-ons that expands content and realism.
Educational value; good for learning about the solar system.

Cons

Limited universe scope and content depth (few galaxies, limited exoplanets, black holes, nebulas).
Clunky controls and navigation; difficulty moving, searching, or teleporting; requests for a joystick or improved UI.
Visible bugs/visual glitches (e.g., Jupiter glitches, water/land turning black, white dots) affecting immersion.
No option for user-created planets or solar systems.
