The DietSensor app is a database that monitors how much the user has eaten and focuses on four dietary values: calories, proteins, carbohydrates and fats. This allows the user to set a limit with regard to the number of calories or carbohydrates they wish to consume each day, for example. The app also monitors whether the user is drinking enough fluid. The DietSensor app can be connected via Bluetooth to various devices such as the SCiO scanner and the DietSensor smart scale.
