# Calculus Increase Brain IQ vs Connections Game!

The clearest difference is review sentiment: Calculus Increase Brain IQ at 75% against Connections Game!'s 30%. Calculus Increase Brain IQ also leads on ads (none vs shown) and iOS requirement (11.0 vs 13.0). Connections Game!'s advantage is rating (4.6 vs 4.1) and in-app purchases (none vs 8). On price and device support there is nothing between them.

Both are free to download. Calculus Increase Brain IQ sells 8 one-off in-app purchases. Connections Game! asks for nothing beyond the download.

Connections Game! holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Connections Game! has 13K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 75% of Calculus Increase Brain IQ's written reviews are positive against 30% of Connections Game!'s, so the app with the better star average is not the one people write more warmly about.
