BigFuture School holds the better App Store score, 4.6 against 2.0. That said, the two scores are not equally well evidenced: BigFuture School has 19K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 80% of Keystone Alg I Practice Tests's written reviews are positive against 28% of BigFuture School's, so the app with the better star average is not the one people write more warmly about.
