# Nomen Memory vs Cortex

The clearest difference is device support: Cortex at 4 against Nomen Memory's 2. Cortex also leads on iOS requirement (15.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Nomen Memory sells 1 one-off in-app purchase and Cortex sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
