# Calculator + vs GraphCalcPro2Go

The clearest difference is ads: GraphCalcPro2Go at none against Calculator +'s shown. Calculator +'s advantage is update cadence (every 4 days vs every 3 months) and ratings volume (10K vs 40). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 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 10K ratings behind it against 40, so its average is the more settled of the two. Written reviews are what separate them: 85% of Calculator +'s written reviews are positive against 80% of GraphCalcPro2Go's.

Calculator + ships an update every 4 days, GraphCalcPro2Go every 3 months. The most recent releases landed on September 24, 2026 and June 1, 2026 respectively.
