# Math. vs RationalNumberCalculator

The clearest difference is in-app purchases: RationalNumberCalculator at none against Math.'s 10. RationalNumberCalculator also leads on rating (5.0 vs 4.7) and iOS requirement (11.0 vs 13.0). Math.'s advantage is ads (none vs shown) and ratings volume (1.6K vs 6). On price and device support there is nothing between them.

Both are free to download. Math. sells 10 in-app purchases, starting at $9.99 per month. RationalNumberCalculator asks for nothing beyond the download.

RationalNumberCalculator holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Math. has 1.6K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 74% of Math.'s written reviews are positive against 64% of RationalNumberCalculator's, so the app with the better star average is not the one people write more warmly about.

Math. ships an update every 3 months, RationalNumberCalculator every 9 months. The most recent releases landed on September 22, 2026 and June 26, 2026 respectively.
