# Calc vs ProKit

The clearest difference is ratings volume: Calc at 41 against ProKit's 1. Calc also leads on iOS requirement (15.1 vs 18). ProKit's advantage is rating (5.0 vs 4.8). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ProKit holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Calc has 41 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Calc ships an update every 3 weeks, ProKit every 2 weeks. The most recent releases landed on September 7, 2026 and September 2, 2026 respectively.
