# Jurassic Survivor vs Rio Rex

The clearest difference is rating: Jurassic Survivor at 4.6 against Rio Rex's 4.1. Jurassic Survivor also leads on update cadence (every 2 months vs every 11 months) and ratings volume (1K vs 50). Rio Rex's advantage is ads (none vs shown) and iOS requirement (9.0 vs 15.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Jurassic Survivor sells 15 one-off in-app purchases and Rio Rex sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Jurassic Survivor holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Jurassic Survivor has 1K ratings behind it against 50, so its average is the more settled of the two. Written reviews complicate that: 68% of Jurassic Survivor's written reviews are positive against 74% of Rio Rex's, so the app with the better star average is not the one people write more warmly about.

Jurassic Survivor ships an update every 2 months, Rio Rex every 11 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
