Verdict

The clearest difference is rating: Math Oral Calculation at 5.0 against zFuse's 4.4. Math Oral Calculation also leads on price ($0.99 vs $4.99) and iOS requirement (10.0 vs 16.0). zFuse's advantage is update cadence (every 3 weeks vs every 35 months) and review sentiment (78% vs 50%). On ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Math Oral Calculation holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: zFuse has 226 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 78% of zFuse's written reviews are positive against 50% of Math Oral Calculation's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

zFuse ships an update every 3 weeks, Math Oral Calculation every 35 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
