# Stack vs Align

The clearest difference is ads: Stack at none against Align's shown. Align's advantage is iOS requirement (17 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Stack sells 1 one-off in-app purchase and Align sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
