This app only works for the sync with the kids scale, forget the rest. All other functions may, if you are lucky, work for some time but they will then (suddenly and without any tangible cause) cease to operate, making all your history data (in our case of 7 weeks) useless because you will have to switch to another app that actually works. Use this only for the scale sync, nothing else. Support does not work, in fact I doubt that it exists...
