# On vs Vampire Story

The clearest difference is review sentiment: Vampire Story at 84% against On's 0%. Vampire Story also leads on price (Free vs $0.99) and ratings volume (3.3K vs 1). On's advantage is in-app purchases (none vs 6) and ads (none vs shown). On device support there is nothing between them.

Vampire Story is free to download; On costs $0.99 up front. Vampire Story sells 6 one-off in-app purchases. On asks for nothing beyond the download.

On holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Vampire Story has 3.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of On's written reviews are positive against 84% of Vampire Story's, so the app with the better star average is not the one people write more warmly about.

On ships an update every 25 months, Vampire Story every 7 months. The most recent releases landed on October 24, 2026 and November 2, 2026 respectively.
