# Cretapedia vs Odyssey XR

The clearest difference is rating: Cretapedia at 4.6 against Odyssey XR's 3.1. Cretapedia also leads on ratings volume (1.7K vs 61) and update cadence (monthly vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Cretapedia sells 10 in-app purchases, starting at $13.99 per month and Odyssey XR sells 14 in-app purchases, starting at $19.99 per year. Whichever you choose, the download price is not the number that matters.

Cretapedia holds the better App Store score, 4.6 against 3.1. That said, the two scores are not equally well evidenced: Cretapedia has 1.7K ratings behind it against 61, so its average is the more settled of the two. Written reviews point the same way: 43% of Cretapedia's written reviews are positive against 41% of Odyssey XR's.

Cretapedia ships an update monthly, Odyssey XR every 2 months. The most recent releases landed on October 22, 2026 and October 25, 2026 respectively.
