# 3D Solar System vs Cosmic Walk

The clearest difference is rating: Cosmic Walk at 5.0 against 3D Solar System's 4.4. Cosmic Walk also leads on in-app purchases (none vs 12) and ads (none vs shown). 3D Solar System's advantage is ratings volume (1.7K vs 2). On price, update cadence and device support there is nothing between them.

Both are free to download. 3D Solar System sells 12 in-app purchases, starting at $7.99 per 7 days. Cosmic Walk asks for nothing beyond the download.

Cosmic Walk 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 2, so its average is the more settled of the two.

3D Solar System ships an update fortnightly, Cosmic Walk every 2 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
