# LUMEN vs Mastering Everest

The clearest difference is iOS requirement: LUMEN at 16.0 against Mastering Everest's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. LUMEN sells 1 one-off in-app purchase and Mastering Everest sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
