Downloaded, opened for 5 minutes and immedately uninstalled for multiple reasons. Firstly there should not be an action to 'check your weight everyday' this is unhealthy behaviour and can lead to eating disorders. Its obsessive, if you really want to track your weight then weighing yourself once a week is plenty. On top of that the 'cut out sugar/carbs etc' is also unhealthy. None of this is needed to keep fit and everything in moderation is key.
