# Atom Run vs Monster Boy

The clearest difference is price: Atom Run at $2.99 against Monster Boy's $24.99. Atom Run also leads on ratings volume (46 vs 8) and review sentiment (58% vs 50%). Monster Boy's advantage is rating (4.6 vs 3.8) and update cadence (every 5 weeks vs every 17 months). On ads, in-app purchases and device support there is nothing between them.

Atom Run costs $2.99 and Monster Boy $24.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Monster Boy holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: Atom Run has 46 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 58% of Atom Run's written reviews are positive against 50% of Monster Boy's, so the app with the better star average is not the one people write more warmly about.

Atom Run ships an update every 17 months, Monster Boy every 5 weeks. The most recent releases landed on September 23, 2026 and September 19, 2026 respectively.
