# Numerology Calculator vs CrysTalk

The clearest difference is iOS requirement: CrysTalk at 17.0 against Numerology Calculator's 26.1. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Numerology Calculator sells 1 one-off in-app purchase and CrysTalk sells 1 in-app purchase, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
