# Galaxy Idle vs Astro Builder

The clearest difference is rating: Astro Builder at 4.7 against Galaxy Idle's 4.4. Astro Builder also leads on ratings volume (3.3K vs 258). Galaxy Idle's advantage is review sentiment (53% vs 34%) and update cadence (every 4 months vs every 11 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Galaxy Idle sells 8 one-off in-app purchases and Astro Builder sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Astro Builder holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Astro Builder has 3.3K ratings behind it against 258, so its average is the more settled of the two. Written reviews complicate that: 53% of Galaxy Idle's written reviews are positive against 34% of Astro Builder's, so the app with the better star average is not the one people write more warmly about.

Galaxy Idle ships an update every 4 months, Astro Builder every 11 months. The most recent releases landed on October 17, 2026 and October 16, 2026 respectively.
