Stopme is Android application for tracking time. Example of a floating window and floating button to track time anywhere.
In this suggestion,i suggest adding a ideal kilo calculator to the application,when user import their height and weight the calculator will tell the user their ideal kilo and the calories they should gain in one day.
Adding this calculator will help users to see what their ideal kilo is and how much is the maximum calories they can gain in a day.
