# Quantum Fusion vs Moonkeeper

The clearest difference is ads: Quantum Fusion at none against Moonkeeper's shown. Moonkeeper's advantage is device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Quantum Fusion sells 1 one-off in-app purchase and Moonkeeper sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
