Verdict
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.
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. Galaxy Attack sells 15 in-app purchases, starting at $9.99 per month. Idle Alien asks for nothing beyond the download.
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.
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.
