Ahead of World No Tobacco Day on Friday, smokers who have been fighting a lonely battle against nicotine addiction were given another option in their quest to kick the habit.

Keio University and CureApp Inc., a Tokyo-based medical technology startup, announced Thursday that a clinical trial has proven the effectiveness of their smartphone app designed to help smokers quit.

The app analyzes information from patients undergoing smoking cessation treatment, such as their health condition and the level of carbon monoxide in their breath, in order to give them daily advice on what they should do to keep themselves from lighting up.
