Verdict

The call

The clearest difference is rating: DOP 4 at 4.6 against Math Challenge's 3.7. DOP 4 also leads on ratings volume (264K vs 10) and chart position (#188 vs unranked). Math Challenge's advantage is in-app purchases (none vs 16) and review sentiment (100% vs 71%). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

DOP 4 holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: DOP 4 has 264K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 100% of Math Challenge's written reviews are positive against 71% of DOP 4's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Math Challenge ships an update every 2 months, DOP 4 every 4 weeks. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
