# PDF助手 vs Memory Game Simulator

PDF助手 and Memory Game Simulator are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. PDF助手 sells 3 in-app purchases, starting at $0.99 per 7 days and Memory Game Simulator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
