# Calculator ∞ vs Desmos Graphing Calculator

The clearest difference is price: Desmos Graphing Calculator at Free against Calculator ∞'s $5.99. Desmos Graphing Calculator also leads on in-app purchases (none vs 4). Calculator ∞'s advantage is rating (4.7 vs 4.3) and ratings volume (6.3K vs 1.3K). On review sentiment, update cadence, ads and chart position there is nothing between them.

Desmos Graphing Calculator is free to download; Calculator ∞ costs $5.99 up front. Calculator ∞ sells 4 in-app purchases, starting at $3.49 per month. Desmos Graphing Calculator asks for nothing beyond the download.

Calculator ∞ holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 6.3K and 1.3K respectively. Written reviews complicate that: 75% of Calculator ∞'s written reviews are positive against 80% of Desmos Graphing Calculator's, so the app with the better star average is not the one people write more warmly about.
