The 336 App
A quit-vaping and quit-smoking app with one job: get you through the first 336 hours cold turkey. No streaks, no mascots, no money counters — a clinical, hour-by-hour countdown through nicotine withdrawal, with briefings that tell you what your body is doing and what to do about it.

THE FOUR PHASES
A 336-hour mission clock
You tap "I quit now" and the clock starts. Every one of the 336 hours has its own card: what's happening in your body, how it will feel, and what to do about it — drawn from the same clinical timeline as this site.
Briefings timed to withdrawal, not to a schedule
Audio and notification briefings are front-loaded to match the chemical craving cycle — hourly through the first 48 hours, tapering as withdrawal shifts from chemistry to habit. They arrive only during the waking hours you set.
The Battle Map
All 14 days × 24 hours on one grid, colored by phase. You can see exactly where you are, what's behind you, and how much of the hard part is left.
SOS mode for cravings
A craving lasts 3-5 minutes. SOS is a 60-second guided breathing exercise built for exactly that window — open it when a craving hits and ride it out.
Built for vaping and smoking
Pick your delivery system — vaping, smoking, or both — and every briefing and piece of tactical advice adapts to it.
No streaks, no money counters
No gimmicks, no guilt mechanics, no savings calculators. 336 is a dashboard for your body: the only numbers on screen are the ones your nervous system is producing.
THE GUIDE BEHIND THE APP
Everything the app briefs you on is published free on this site — the full hour-by-hour timeline, every withdrawal symptom, and the science of why cold turkey works.
Frequently asked questions
Is the 336 app free?
336 is free to download on iOS and Android and free to start. The full 336-hour program is unlocked by an optional subscription (weekly, with a free trial, or annual).
Does 336 work for quitting smoking too?
Yes. During setup you choose vaping, smoking, or both, and the briefings and tactical advice adapt to your delivery system. The underlying clinical timeline — nicotine clearance by hour 72, receptor recalibration by day 14 — is the same.
Do I need an account?
No. There is no sign-up and no profile. Your quit clock and preferences live on your device.
How is 336 different from other quit-vaping apps?
Most quit apps are streak counters with motivational quotes. 336 is a clinical countdown: it treats the first 14 days as a defined 336-hour physiological event, briefs you through each hour of it, and ends. No community feed, no money-saved tracker, no gamification.
What happens if I relapse?
You reset the clock — the app asks what triggered it and logs the attempt, and your setup carries over so restarting takes seconds. Previous attempts are counted, not shamed.
What languages does the app support?
The app is available in 20 languages, matching this website.
