# CalculatorPro vs CaIculator

The clearest difference is in-app purchases: CalculatorPro at none against CaIculator's 1. CalculatorPro also leads on ads (none vs shown) and update cadence (every 3 days vs every 5 months). CaIculator's advantage is ratings volume (27 vs 1) and iOS requirement (12.0 vs 26.0). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. CaIculator sells 1 one-off in-app purchase. CalculatorPro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for CalculatorPro against 4.9 for CaIculator. That said, the two scores are not equally well evidenced: CaIculator has 27 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.

CalculatorPro ships an update every 3 days, CaIculator every 5 months. The most recent releases landed on October 29, 2026 and November 3, 2026 respectively.
