# qtVlm vs Compass Toolkit

The clearest difference is iOS requirement: qtVlm at 12.0 against Compass Toolkit's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. qtVlm sells 1 one-off in-app purchase and Compass Toolkit sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
