Hi again, glacesoundracer - glad to hear you have an app for cigarettes that you feel is helpful. I also was hoping others would chime in here once they saw your inquiry.
If you want to expand your reach a little, you may want to post the same question on our COPD Facebook platform. We have many members there who interact throughout the day on all aspects of COPD.
You will find the link on the bottom of this page.
Wishing you well,
Leon (site moderator COPD.net)
