# Manic Marble 3 vs Reaction Test Pro

The clearest difference is review sentiment: Manic Marble 3 at 77% against Reaction Test Pro's 53%. Manic Marble 3 also leads on iOS requirement (13.0 vs 15.0). Reaction Test Pro's advantage is rating (4.3 vs 4.0) and ratings volume (196 vs 8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Reaction Test Pro holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Reaction Test Pro has 196 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 77% of Manic Marble 3's written reviews are positive against 53% of Reaction Test Pro's, so the app with the better star average is not the one people write more warmly about.

Manic Marble 3 ships an update every 11 months, Reaction Test Pro every 9 months. The most recent releases landed on June 3, 2026 and September 21, 2026 respectively.
