A lot of pèople think the Samsung fit hardware & software on their recent phones is a gimmick. Well if you use it properly its not and I have lost a lot of weight using the system. You can enter what you eat into the system for a calorie count from an extensive database including many supermarket products. You can accurately measure your daily activity (and calorie burn) plus give yourself goals using the system and also measure your heartbeat and o2 levels. Overall it has worked very well for me and you have loads of data on how you are doing. I have lost over a stone using the system.
