It does what it supposed to. But is a bit unintuitive and clumsy in its handling. Language and units of measurement cannot be set in the app. I am from Germany and want the app in full German with European metric units. (My phone is set to English, though). I found instructions in the web to adjust it via website, no success. This is somewhat frustrating. Also scrollig through the units and not being able to hard key them in is also quite tedious. The barcode scanner is quite nice though.
