# Marquer vs Cortex

The clearest difference is iOS requirement: Marquer at 15.1 against Cortex's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Marquer sells 2 in-app purchases, starting at $6.99 per month and Cortex sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
