# Algo Viewer vs Learn SQL

The clearest difference is iOS requirement: Learn SQL at 15.0 against Algo Viewer's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Algo Viewer sells 1 one-off in-app purchase and Learn SQL sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
