# Calculator HD Pro vs iCalc

The clearest difference is price: iCalc at Free against Calculator HD Pro's $9.99. iCalc also leads on update cadence (every 6 days vs every 2 months) and iOS requirement (12.0 vs 15.2). Calculator HD Pro's advantage is ads (none vs shown) and ratings volume (11K vs 38). On review sentiment, in-app purchases, monetization model and device support there is nothing between them.

iCalc is free to download; Calculator HD Pro costs $9.99 up front. Calculator HD Pro sells 2 one-off in-app purchases and iCalc sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Calculator HD Pro holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Calculator HD Pro has 11K ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 95% of Calculator HD Pro's written reviews are positive against 100% of iCalc's, so the app with the better star average is not the one people write more warmly about.

Calculator HD Pro ships an update every 2 months, iCalc every 6 days. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
