Smart Body Analyzer is a complete health tracking scale. Though it appears like a normal weighing scale, it provides a detailed health data.

It measures body fat percentage, heart rate and room air quality, along with your weight. The data can be synced with the server using a mobile app.

You can easily set goals and track your progress. The app can plot graphs of the air quality, instructing you to clean the room as and when required.
