# 3D Solar System vs Earth Rotation

The clearest difference is price: 3D Solar System at Free against Earth Rotation's $0.99. 3D Solar System also leads on update cadence (fortnightly vs every 22 months) and ratings volume (1.7K vs 1). Earth Rotation's advantage is rating (5.0 vs 4.4) and in-app purchases (none vs 10). On device support and iOS requirement there is nothing between them.

3D Solar System is free to download; Earth Rotation costs $0.99 up front. 3D Solar System sells 10 in-app purchases, starting at $9.99 per month. Earth Rotation asks for nothing beyond the download.

Earth Rotation holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: 3D Solar System has 1.7K ratings behind it against 1, so its average is the more settled of the two.

3D Solar System ships an update fortnightly, Earth Rotation every 22 months. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
