# Galaxy Collider vs Planet Gravity

The clearest difference is price: Galaxy Collider at $0.99 against Planet Gravity's $11.00. Galaxy Collider also leads on in-app purchases (none vs 1) and ads (none vs shown). Planet Gravity's advantage is rating (4.2 vs 3.9) and update cadence (every 4 months vs every 11 months). On device support there is nothing between them.

Galaxy Collider costs $0.99 and Planet Gravity $11.00 up front. Planet Gravity sells 1 one-off in-app purchase. Galaxy Collider asks for nothing beyond the download.

Planet Gravity holds the better App Store score, 4.2 against 3.9. Both are backed by a comparable volume of ratings — 17 and 54 respectively. Written reviews complicate that: 61% of Galaxy Collider's written reviews are positive against 44% of Planet Gravity'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, Planet Gravity every 4 months. The most recent releases landed on October 12, 2026 and October 15, 2026 respectively.
