# eCalculator vs CaIculator

The clearest difference is rating: CaIculator at 4.9 against eCalculator's 4.6. CaIculator also leads on review sentiment (100% vs 80%). eCalculator's advantage is ratings volume (156 vs 27). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. eCalculator sells 1 one-off in-app purchase and CaIculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CaIculator holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: eCalculator has 156 ratings behind it against 27, so its average is the more settled of the two. Written reviews point the same way: 80% of eCalculator's written reviews are positive against 100% of CaIculator's.

eCalculator ships an update every 3 months, CaIculator every 5 months. Both last shipped on November 3, 2026.
