Verdict
The clearest difference is rating: Space Shooter at 4.6 against Sky Invaders's 1.0. Space Shooter also leads on update cadence (every 2 months vs every 23 months) and ratings volume (3.3K vs 1). Sky Invaders's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Space Shooter sells 10 one-off in-app purchases. Sky Invaders asks for nothing beyond the download.
Space Shooter holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: Space Shooter has 3.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Sky Invaders's written reviews are positive against 41% of Space Shooter's, so the app with the better star average is not the one people write more warmly about.
Sky Invaders ships an update every 23 months, Space Shooter every 2 months. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
