# PCalc vs Calculator +

The clearest difference is price: Calculator + at Free against PCalc's $9.99. Calculator + also leads on update cadence (every 4 days vs every 6 weeks) and ratings volume (10K vs 770). PCalc's advantage is ads (none vs shown) and chart position (#69 vs unranked). On rating, review sentiment, in-app purchases and monetization model there is nothing between them.

Calculator + is free to download; PCalc costs $9.99 up front. PCalc sells 4 one-off in-app purchases and Calculator + sells 12 in-app purchases, starting at $4.99 per month. 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 PCalc against 4.6 for Calculator +. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 770, so its average is the more settled of the two. Written reviews are what separate them: 84% of PCalc's written reviews are positive against 85% of Calculator +'s.

PCalc ships an update every 6 weeks, Calculator + every 4 days. Both last shipped on September 24, 2026.
