# Roller Coaster Builder Mobile vs Ultimate Coaster 2

The clearest difference is rating: Roller Coaster Builder Mobile at 4.6 against Ultimate Coaster 2's 4.1. Roller Coaster Builder Mobile also leads on update cadence (monthly vs every 6 months) and ratings volume (7.4K vs 1.9K). Ultimate Coaster 2's advantage is ads (none vs shown). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Roller Coaster Builder Mobile sells 10 one-off in-app purchases and Ultimate Coaster 2 sells 16 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Roller Coaster Builder Mobile holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 7.4K and 1.9K respectively. Written reviews complicate that: 70% of Roller Coaster Builder Mobile's written reviews are positive against 74% of Ultimate Coaster 2's, so the app with the better star average is not the one people write more warmly about.

Roller Coaster Builder Mobile ships an update monthly, Ultimate Coaster 2 every 6 months. Both last shipped on October 18, 2026.
