# Units Calculator vs dB Meter

The clearest difference is iOS requirement: Units Calculator at 15.0 against dB Meter's 17.0. On price, ads, 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.
