Want to know how much fat you’re burning? Calorie and exercise trackers have become popular tools for creating and sticking to a weight loss plan, but they often rely more on stored data and averages than they do on personalized metrics.

How much fat are you actually burning each day? And are you really burning off fat stores, or are you just powering through with carbs and sugars? With a simple breath, Levl’s new device can tell you.

Levl has essentially the same design and functionality as a breathalyzer. In order to get a reading out of the device, you must first inhale for 5 seconds, then steadily blow into a tube for another 5 seconds.

Acetone is produced in excess only when the body is burning fat rather than carbs or simple sugars.

The recommendation is to use the device at least twice a day so that you can take a baseline reading first thing in the morning and at least one reading later on. Still, more data is always better. The data is conveyed by an app that calculates the amount of fat that you are burning each day, and charts patterns over a longer period of time.

A long, sustained breath into this little device will provide a readout of how much fat you're burning.

While the hardware is advanced in its ability to recognize minute chemical traces, the software still has a lot of room for improvement. The app currently tracks daily use and creates graphs of the trends, but it is up to the user to recognize patterns and search for insight. For example, you may notice that on Mondays you tend to burn less fat, but if you don't link that back to your weekend eating and drinking habits, Levl isn't going to do it for you.

The Levl app helps users track their fat-burning patterns.

Levl will need some app and algorithm improvements in order to compete with more intuitive weight loss apps, but there's certainly potential for it to become a major player in weight loss planning tools. As more users begin inputting data, the company will likely gain an increased capacity to draw insights from the data and make suggestions to users about how to maximize weight loss. We can't wait to see Levl reach the next, er, level of health tracking technology.
