# CoralCalc vs ReefMind

The clearest difference is iOS requirement: CoralCalc at 13.0 against ReefMind's 15.1. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. CoralCalc sells 1 in-app purchase, starting at $4.99 per month and ReefMind sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
