# Shatterbrain vs Lumen

The clearest difference is ads: Lumen at none against Shatterbrain's shown. Shatterbrain's advantage is iOS requirement (15.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

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