LAS VEGAS— The company that created one of the first smartphone breathalyzers is using its breath-analyzing tech for a new product.

It's called Mint and it analyzes your breath and lets you know how stinky (or fresh) your breath is.

The Mint works similar to the way smartphone breathalyzers do: breathe into the device for a few seconds and the app provides the reading that rates your breath quality.

It uses a sensor that measures bad breath-causing compounds in your mouth, including the amount of hydrogen sulfide, methyl mercaptan and hydrogen disulfide. It also measures the amount of water in your mouth's mucus membrane to detect whether or not you're dehydrated— dehydration is one cause of bad breath.

During the demo I saw with an early prototype, the entire process took about 12 seconds but a company spokesperson said the final version will likely cut that time to less than 10 seconds.

The iOS app syncs with Apple's HealthKit and the Android app will be compatible with the Samsung Galaxy S4, S5 and Nexus 5. Both apps track your breath quality over time and allow you to compete with friends in leaderboards.

Breathometer is in the midst of a crowdfunding campaign on Indiegogo. Two days into the campaign, the company has already raised more than $20,000 of its $25,000 goal.

The company says it expects to make Mint available to backers by August 2015.
