# Stack Sort vs Fill and Flow

The clearest difference is ads: Stack Sort at none against Fill and Flow's shown. Stack Sort also leads on iOS requirement (9.0 vs 12.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
