# Duct Mate vs DuctSizer Pro

The clearest difference is iOS requirement: DuctSizer Pro at 17.6 against Duct Mate's 26.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Duct Mate sells 1 one-off in-app purchase and DuctSizer Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
