# Galaxy Collider vs Sandbox Planet

The clearest difference is price: Sandbox Planet at Free against Galaxy Collider's $0.99. Sandbox Planet also leads on rating (4.5 vs 3.9) and update cadence (every 3 months vs every 11 months). Galaxy Collider's advantage is in-app purchases (none vs 6) and ads (none vs shown). On device support there is nothing between them.

Sandbox Planet is free to download; Galaxy Collider costs $0.99 up front. Sandbox Planet sells 6 one-off in-app purchases. Galaxy Collider asks for nothing beyond the download.

Sandbox Planet holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: Sandbox Planet has 304 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 61% of Galaxy Collider's written reviews are positive against 52% of Sandbox Planet's, so the app with the better star average is not the one people write more warmly about.

Galaxy Collider ships an update every 11 months, Sandbox Planet every 3 months. Both last shipped on October 29, 2026.
