# Galaxy Attack vs Idle Anomaly

The clearest difference is update cadence: Galaxy Attack at every 4 days against Idle Anomaly's every 5 weeks. Galaxy Attack also leads on ratings volume (657K vs 364) and review sentiment (52% vs 38%). Idle Anomaly's advantage is iOS requirement (13.0 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Galaxy Attack sells 15 in-app purchases, starting at $9.99 per month and Idle Anomaly sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Galaxy Attack against 4.7 for Idle Anomaly. That said, the two scores are not equally well evidenced: Galaxy Attack has 657K ratings behind it against 364, so its average is the more settled of the two.
