About SmokeClock
Who built this app, why, and how we treat health information.
Why SmokeClock exists
Most quit-smoking advice you'll find online tells you to stop cold turkey. The research is mixed: cold turkey works for some people, but gradual reduction works for many others, and for most heavy smokers, an abrupt stop fails within a week. SmokeClock was built around that observation: an iPhone app that schedules your cigarettes throughout the day and slowly stretches the gap between them, until you reach zero on a date you choose.
No willpower theatre. No premium plan locked behind paywalls. Just a timer and a plan you can stick to.
Who I am
My name is Josep Salvat. I'm an independent iOS developer based in Spain. I built SmokeClock after watching people close to me struggle with cold-turkey approaches that didn't fit their life or smoking pattern.
I'm not a doctor. SmokeClock is not medical advice. The app implements a gradual-reduction schedule that mirrors patterns described in published smoking-cessation literature, but it does not replace consultation with a healthcare professional, and it is not a regulated medical device.

Your smoking plan, schedule and detailed progress history stay on your iPhone, stored locally with Apple's SwiftData, no account, no data broker, no cross-app tracking. The app does send limited anonymous usage events so we can tell whether it works. Read the full Privacy Policy.
