# Celestial Assault vs Space

The clearest difference is in-app purchases: Space at none against Celestial Assault's 10. Space also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 89%). Celestial Assault's advantage is ratings volume (45 vs 3) and iOS requirement (6.0 vs 13.0). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Celestial Assault sells 10 one-off in-app purchases. Space asks for nothing beyond the download.

Space holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Celestial Assault has 45 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 89% of Celestial Assault's written reviews are positive against 100% of Space's.

Celestial Assault ships an update every 6 weeks, Space every 2 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
