Samsung's Galaxy S4 smartphone will support a number of health peripherals to interact with its S Health app.
The S Band is a wearable accelerometer that can hook up to your Galaxy S4 and provide further data on all the exercise you're doing. Inside the S Band is a pedometer, which feeds the updated S Health app information.
The S Band will send to your phone details of steps taken, calories burnt and even sleep patterns, to provide more data on your activity and help with your fitness training.
The SGS4 has a built-in pedometer and can also track data, so the S Band is more an extension device, or handy if you don't have your mobile phone with you.S Scale
Samsung's accessory line-up is starting to mirror that of Withings and Fitbit, both of which have their own wireless set of scales.
This device is designed to provide the S Health app with precise data on how much you weigh, as part of a diet or fitness regime.
