# Calculator Pro vs iCalc

The clearest difference is ads: Calculator Pro at none against iCalc's shown. Calculator Pro also leads on rating (5.0 vs 4.6). iCalc's advantage is update cadence (every 6 days vs every 3 weeks) and ratings volume (38 vs 4). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calculator Pro sells 3 in-app purchases, starting at $1.99 per 7 days 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 Pro holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: iCalc has 38 ratings behind it against 4, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Calculator Pro ships an update every 3 weeks, iCalc every 6 days. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
