# Ring Sizer vs PetSOS

Ring Sizer and PetSOS are too close to call on the numbers: across 3 compared parameters — price, in-app purchases and iOS requirement among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Ring Sizer sells 3 in-app purchases, starting at $0.99 per month and PetSOS sells 4 in-app purchases, starting at $0.99 per 3 months. Whichever you choose, the download price is not the number that matters.
