# GraphCalcPro2Go vs Calculator +ㅤ

The clearest difference is monetization model: GraphCalcPro2Go at free with in-app purchases against Calculator +ㅤ's subscription. GraphCalcPro2Go also leads on ads (none vs shown) and review sentiment (80% vs 46%). Calculator +ㅤ's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (4.5K vs 40). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. GraphCalcPro2Go sells 1 one-off in-app purchase and Calculator +ㅤ sells 6 in-app purchases, starting at $2.99 per 7 days. 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 GraphCalcPro2Go against 4.6 for Calculator +ㅤ. That said, the two scores are not equally well evidenced: Calculator +ㅤ has 4.5K ratings behind it against 40, so its average is the more settled of the two. Written reviews are what separate them: 80% of GraphCalcPro2Go's written reviews are positive against 46% of Calculator +ㅤ's.

GraphCalcPro2Go ships an update every 3 months, Calculator +ㅤ fortnightly. The most recent releases landed on June 1, 2026 and September 23, 2026 respectively.
