# Decibel Meter vs Ring Sizer

Decibel Meter and Ring Sizer are too close to call on the numbers: across 4 compared parameters — price, in-app purchases, device support 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. Decibel Meter sells 2 in-app purchases, starting at $6.49 per 7 days and Ring Sizer sells 6 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
