# Roblox vs Astro Builder

The clearest difference is ads: Roblox at none against Astro Builder's shown. Roblox also leads on update cadence (weekly vs every 11 months) and review sentiment (60% vs 33%). Astro Builder's advantage is rating (4.7 vs 4.5). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Roblox sells 16 in-app purchases, starting at $4.99 per month 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 4.5. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 3.3K, so its average is the more settled of the two. Written reviews complicate that: 60% of Roblox's written reviews are positive against 33% of Astro Builder's, so the app with the better star average is not the one people write more warmly about.

Roblox ships an update weekly, Astro Builder every 11 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
