# One vs Year Count

The clearest difference is ads: Year Count at none against One's shown. One's advantage is iOS requirement (15.6 vs 17.0). 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.
