# Quack Sort vs PureMemory

The clearest difference is in-app purchases: PureMemory at none against Quack Sort's 17. PureMemory also leads on ads (none vs shown). Quack Sort's advantage is chart position (#120 vs unranked) and iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Quack Sort sells 17 one-off in-app purchases. PureMemory asks for nothing beyond the download.
