# Mercury vs UnitFlow

The clearest difference is ads: Mercury at none against UnitFlow's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Mercury sells 5 one-off in-app purchases and UnitFlow sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
