Verdict

The call

The clearest difference is review sentiment: Idle Alien at 100% against Galaxy Attack's 52%. Idle Alien also leads on in-app purchases (none vs 16). Galaxy Attack's advantage is ratings volume (654K vs 123) and update cadence (every 4 days vs every 11 days). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Galaxy Attack holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Galaxy Attack has 654K ratings behind it against 123, so its average is the more settled of the two. Written reviews complicate that: 52% of Galaxy Attack's written reviews are positive against 100% of Idle Alien's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Galaxy Attack ships an update every 4 days, Idle Alien every 11 days. The most recent releases landed on September 26, 2026 and July 4, 2026 respectively.
