The app is quite well and so is the scale. One big problem is the fact that the kg recommendations based on height are wrong for males, which messes the whole scoring. For example: the recommended weight for a 185cm male, is no more than 74.2 kgs. Can you imagine how high the "fat" ratio is for ab individual that for the same height has a around 85 kg? Btw, the recommended weight that is mentioned in several studies, is 85 kg. If my settings are wrong, let me know!
