Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Jurassic Survivor ships an update every 2 months, Rio Rex every 11 months. Both last shipped on October 24, 2026.
