# Idle Roller Coaster vs Ultimate Coaster 2

The clearest difference is rating: Idle Roller Coaster at 4.8 against Ultimate Coaster 2's 4.1. Idle Roller Coaster also leads on update cadence (fortnightly vs every 6 months) and ratings volume (186K vs 1.9K). Ultimate Coaster 2's advantage is ads (none vs shown) and review sentiment (74% vs 65%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Idle Roller Coaster sells 3 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.

Idle Roller Coaster holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Idle Roller Coaster has 186K ratings behind it against 1.9K, so its average is the more settled of the two. Written reviews complicate that: 65% of Idle Roller Coaster'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.

Idle Roller Coaster ships an update fortnightly, Ultimate Coaster 2 every 6 months. The most recent releases landed on October 23, 2026 and October 21, 2026 respectively.
