# Purify the World vs Horizon Bound

The clearest difference is rating: Purify the World at 5.0 against Horizon Bound's 3.6. Purify the World also leads on iOS requirement (13.0 vs 15.0). Horizon Bound's advantage is review sentiment (40% vs 25%) and ratings volume (14 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Purify the World sells 7 one-off in-app purchases and Horizon Bound sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Purify the World holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Horizon Bound has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Purify the World's written reviews are positive against 40% of Horizon Bound's, so the app with the better star average is not the one people write more warmly about.

Purify the World ships an update every 6 weeks, Horizon Bound every 3 weeks. Both last shipped on October 30, 2026.
