# Kero vs Maestro

The clearest difference is iOS requirement: Kero at 16.4 against Maestro's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Kero sells 3 in-app purchases, starting at $9.99 per 7 days and Maestro sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
