# Space Shooter vs Galaxy Invaders

The clearest difference is rating: Space Shooter at 4.6 against Galaxy Invaders's 4.2. Space Shooter also leads on ratings volume (3.3K vs 58) and iOS requirement (13.0 vs 15.0). Galaxy Invaders's advantage is update cadence (every 2 weeks vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Space Shooter sells 16 one-off in-app purchases and Galaxy Invaders sells 27 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Space Shooter holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Space Shooter has 3.3K ratings behind it against 58, so its average is the more settled of the two. Written reviews complicate that: 41% of Space Shooter's written reviews are positive against 47% of Galaxy Invaders's, so the app with the better star average is not the one people write more warmly about.

Space Shooter ships an update every 2 months, Galaxy Invaders every 2 weeks. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
