# Calcularium vs ClevCalc

Calcularium and ClevCalc both sit at 4.6 stars, but that hides the real split: 91% of ClevCalc's written reviews are positive against 66% of Calcularium's. ClevCalc also leads on ratings volume (14K vs 2.2K) and iOS requirement (15.0 vs 18.0). Calcularium's advantage is update cadence (fortnightly vs monthly). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Calcularium sells 7 in-app purchases, starting at $3.99 per month and ClevCalc sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Calcularium against 4.7 for ClevCalc. That said, the two scores are not equally well evidenced: ClevCalc has 14K ratings behind it against 2.2K, so its average is the more settled of the two. Written reviews are what separate them: 66% of Calcularium's written reviews are positive against 91% of ClevCalc's.

Calcularium ships an update fortnightly, ClevCalc monthly. Both last shipped on November 11, 2026.
