# Unit Converter vs Photo Saving Assistant

The clearest difference is iOS requirement: Unit Converter at 12.0 against Photo Saving Assistant's 18.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Unit Converter sells 1 one-off in-app purchase and Photo Saving Assistant sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
