# MathMod vs Dual N

The clearest difference is rating: MathMod at 4.5 against Dual N's 3.6. MathMod also leads on in-app purchases (none vs 4) and iOS requirement (12.0 vs 17.0). Dual N's advantage is ratings volume (8 vs 2). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. Dual N sells 4 in-app purchases, starting at $3.99 per month. MathMod asks for nothing beyond the download.

MathMod holds the better App Store score, 4.5 against 3.6. Both are backed by a comparable volume of ratings — 2 and 8 respectively. Written reviews complicate that: 67% of MathMod's written reviews are positive against 72% of Dual N's, so the app with the better star average is not the one people write more warmly about.
