Gravity Tracker App

This app is for exclusive use of participants of the CO-Self-monitoring trial.

This trial is for adults who would otherwise continue to smoke or use other nicotine products. You are downloading this app because you have received an invitation to participate in this trial.

The Gravity Tracker app is intended to be used together with the Gravity CO sensor, which measures the CO level in exhaled breath. The Gravity Tracker app allows you to track, monitor, and learn how your Carbon Monoxide (CO) level is impacted by cigarettes and heated tobacco product consumption
