# Calculator # vs GraphCalcPro2Go

The clearest difference is ads: GraphCalcPro2Go at none against Calculator #'s shown. GraphCalcPro2Go also leads on review sentiment (80% vs 60%). Calculator #'s advantage is ratings volume (36K vs 40) and iOS requirement (12.1 vs 18.6). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Calculator # sells 6 in-app purchases, starting at $1.49 per month and GraphCalcPro2Go sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Calculator # against 4.6 for GraphCalcPro2Go. That said, the two scores are not equally well evidenced: Calculator # has 36K ratings behind it against 40, so its average is the more settled of the two. Written reviews are what separate them: 60% of Calculator #'s written reviews are positive against 80% of GraphCalcPro2Go's.

Calculator # ships an update every 2 months, GraphCalcPro2Go every 3 months. The most recent releases landed on September 26, 2026 and June 1, 2026 respectively.
