It takes only one breath
We made an X-rayed model of the inside of the lumen device to show its technology and how it works. With one breath into the device, both a C02 and flow meter can accurately measure your metabolism. Not only that, but it's sleek and small design makes it perfect for when you’re on the move but still want to count your calorie intake.
Next to the X-ray video we also made four social videos to show off its features and ease of use.
