>I'd be interested to know how "smoke-free" time is established. Are users self-reporting that they have or haven't smoked with the app? And 28-days of not smoking is great, but it feels dishonest to call that "smoke-free". Well, they're not actually claiming "mission accomplished" after 28-days smoke-free -- they continue to help people stay smoke-free on an ongoing basis. But 28 days seems like a challenging and reasonable milestone to me. (Disclaimer: I invested in QuitGenius)
