ReceptionRating · Positive reviews · Number of ratings

Ultimate Dinosaur Simulator holds the better App Store score, 4.2 against 3.6. That said, the two scores are not equally well evidenced: Ultimate Dinosaur Simulator has 1.8K ratings behind it against 40, so its average is the more settled of the two. Written reviews complicate that: 68% of Dinosaur Assassin's written reviews are positive against 62% of Ultimate Dinosaur Simulator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Dinosaur Assassin ships an update every 6 months, Ultimate Dinosaur Simulator every 7 months. The most recent releases landed on October 8, 2026 and October 13, 2026 respectively.
