Why we built it
Most quit apps start counting the moment you install them. That suits people who have already stopped, but most people aren't there yet. They want to quit, and they need a plan for getting to the day they stop.
DayXero starts earlier. A seven-day prep week helps you learn your triggers, plan what you'll do instead and decide whether to use nicotine replacement. Then it supports you on Quit Day and the weeks after.
What DayXero stands for
- A slip is not a reset. One puff, pouch or cigarette doesn't erase your progress, so the app never resets your count for a slip. It helps you learn from it instead.
- Cravings pass. Craving SOS will walk you through a three-minute urge-surfing session, because a craving peaks and fades within minutes.
- Every kind of nicotine. Cigarettes, vapes and pouches all work in the app, and so does stepping down nicotine replacement.
- Private by default. Your quit data stays on your phone. See our privacy policy.
How we write our guides
The DayXero guides are written by the DayXero team. Every guide follows the same rules:
- Based on public health guidance. We work from the World Health Organization, the NHS, the US CDC and National Cancer Institute (Smokefree.gov), and India's National Tobacco Control Programme. Each guide lists its sources.
- Plain and practical. We write for someone who wants to quit this week, not for a textbook.
- Dated and updated. Each guide shows the date it was last updated. We review guides when health guidance changes.
- Information, not medical advice. Our guides don't replace a doctor or pharmacist, especially for nicotine replacement doses, pregnancy, heart conditions or anyone under 18.
