Our Device

The Invoy device monitors a direct byproduct of fat metabolism that is present in exhaled breath.

Our device uses disposables with highly accurate chemistry. The entire system is simple to use, portable & easy to travel with. You interact with it for 10-15 seconds per day.

Essentially, we are getting to the core of what is happening chemically within the body - instead of basing our program on just a bathroom scale. We want to help drive decisions with the best possible data for you.
