The clearest difference is rating: Fraction Challenge at 4.5 against 2357!'s 4.0. Fraction Challenge also leads on ratings volume (1.5K vs 3). 2357!'s advantage is in-app purchases (none vs 1) and review sentiment (89% vs 70%). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Fraction Challenge sells 1 one-off in-app purchase. 2357! asks for nothing beyond the download.
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.
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.
