ReceptionRating · Positive reviews · Number of ratings

Fraction Challenge holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Fraction Challenge has 1.5K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 89% of 2357!'s written reviews are positive against 70% of Fraction Challenge's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

2357! ships an update every 2 weeks, Fraction Challenge every 2 months. The most recent releases landed on November 2, 2026 and November 11, 2026 respectively.
