# Calculator₊ vs GraphCalcPro2Go

The clearest difference is ads: GraphCalcPro2Go at none against Calculator₊'s shown. GraphCalcPro2Go also leads on review sentiment (80% vs 63%). Calculator₊'s advantage is update cadence (fortnightly vs every 3 months) and ratings volume (1.7M vs 40). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calculator₊ sells 12 in-app purchases, starting at $0.99 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 — 4.7 for Calculator₊ against 4.6 for GraphCalcPro2Go. That said, the two scores are not equally well evidenced: Calculator₊ has 1.7M ratings behind it against 40, so its average is the more settled of the two. Written reviews are what separate them: 63% of Calculator₊'s written reviews are positive against 80% of GraphCalcPro2Go's.

Calculator₊ ships an update fortnightly, GraphCalcPro2Go every 3 months. The most recent releases landed on September 27, 2026 and June 1, 2026 respectively.
