# Graphing Calculator 84 vs MathMod

The clearest difference is in-app purchases: MathMod at none against Graphing Calculator 84's 4. MathMod also leads on ads (none vs shown) and rating (5.0 vs 4.6). Graphing Calculator 84's advantage is ratings volume (5.1K vs 1) and review sentiment (84% vs 67%). On price and device support there is nothing between them.

Both are free to download. Graphing Calculator 84 sells 4 in-app purchases, starting at $1.99 per month. MathMod asks for nothing beyond the download.

MathMod holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Graphing Calculator 84 has 5.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 84% of Graphing Calculator 84's written reviews are positive against 67% of MathMod's, so the app with the better star average is not the one people write more warmly about.
