# Rounding vs Math Master

The clearest difference is ads: Math Master at none against Rounding's shown. Math Master also leads on update cadence (every 5 weeks vs every 12 months) and ratings volume (321 vs 79). Rounding's advantage is review sentiment (64% vs 45%) and iOS requirement (15.0 vs 17.6). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Rounding sells 1 one-off in-app purchase and Math Master sells 5 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Math Master holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 79 and 321 respectively. Written reviews complicate that: 64% of Rounding's written reviews are positive against 45% of Math Master's, so the app with the better star average is not the one people write more warmly about.

Rounding ships an update every 12 months, Math Master every 5 weeks. The most recent releases landed on June 1, 2026 and September 23, 2026 respectively.
