MO holds the better App Store score, 4.6 against 2.3. That said, the two scores are not equally well evidenced: MO has 47 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of 101 Tangrams's written reviews are positive against 80% of MO's, so the app with the better star average is not the one people write more warmly about.
