# Calc Pro vs iCalc

The clearest difference is in-app purchases: Calc Pro at none against iCalc's 3. Calc Pro also leads on rating (4.8 vs 4.6). iCalc's advantage is update cadence (every 6 days vs monthly) and ratings volume (43 vs 6). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. iCalc sells 3 in-app purchases, starting at $0.99 per month. Calc Pro asks for nothing beyond the download.

Calc Pro holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: iCalc has 43 ratings behind it against 6, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Calc Pro ships an update monthly, iCalc every 6 days. Both last shipped on October 24, 2026.
