In recent years, we’ve seen a number of digital health products come to market to help support smoking cessation. SmartQuit is an interesting smoking cessation app out of the Fred Hutchinson Cancer Research Center and the University of Washington with some good data to support it. We’ve also seen pharmaceutical giants like Pfizer explore pairing smoking cessation apps with other interventions, like medications.

Carrot Inc’s Carbon Monoxide breath sensor and its paired smoking-cessation app, Pivot take a new approach to helping people quit smoking.

The breath sensor monitors the carbon monoxide levels in the breath of smokers with the aim of increasing interest in — if not leading to — quitting. Paired with Carrot’s new smoking cessation platform Pivot, the device and app are like a Fitbit for smokers who want to see the effects of their habit in real-time.

“While there has been a torrent of wearable tech to facilitate behavior change in fitness, weight loss and other targets, there’s been no such innovation to help people quit smoking,” said David S. Utley, M.D., founder and CEO of Carrot Inc.

Pivot isn’t a cold-turkey method for smoking cessation; it guides users step by step through their journey from an initial desire to quit, to long-term maintenance, with professional support and information.

We’re living in a health metrics-obsessed world: people track their steps, sleep, calories, and even water intake. But will smokers take to at-home monitoring? It’s the number one preventable death in the U.S., so healthcare companies and loved ones of smokers most certainly hope so.
