# GraphCalcPro2Go vs Calculator Pro

The clearest difference is rating: Calculator Pro at 5.0 against GraphCalcPro2Go's 4.6. Calculator Pro also leads on update cadence (every 3 weeks vs every 3 months) and review sentiment (100% vs 80%). GraphCalcPro2Go's advantage is ratings volume (42 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. GraphCalcPro2Go sells 1 one-off in-app purchase and Calculator Pro sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Calculator Pro holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: GraphCalcPro2Go has 42 ratings behind it against 4, so its average is the more settled of the two.
