336: Quit Smoking Vape Tracker

336 hours. That's how long it takes to break free from nicotine — completely and permanently.

336 is a cold turkey quit smoking and quit vaping app built on clinical science, not motivational fluff. Every hour of your 14-day nicotine detox is mapped with real pharmacological data: what nicotine is doing in your body, what withdrawal symptoms to expect, and when they peak and fade.

No nicotine replacement. No patches. No gum. No gimmicks.

This app is for people who are done. You quit, and 336 tracks your body's recovery hour by hour.

Quit vaping or quit smoking — the same 336 hours

Whether you want to stop vaping a disposable or an e-cigarette, stop smoking cigarettes, or quit nicotine pouches, it is the same drug leaving the same body on the same curve. 336 asks what you are quitting during setup and tunes every briefing to it. Most quit vaping apps are rebadged smoking apps that never mention a vape; this one names the difference.

How it works

• Tap "I Quit Now" and your 336-hour countdown begins
• Each hour shows clinical data: nicotine blood levels, carbon monoxide clearance, receptor recovery, and neurotransmitter normalization
• Watch nicotine and cotinine clear from your bloodstream in real time
• Track your progress through 4 distinct phases of nicotine withdrawal and recovery
• The Battle Map gives you a bird's-eye view of all 14 days — see how far you've come and what's ahead

The four phases

Phase 1 — Acute Withdrawal (Hours 1-72). The peak. Nicotine leaves your blood within 48 hours. Carbon monoxide clears in 24. These are the hardest hours of the sprint, and 336 walks you through every one.

Phase 2 — The Drop (Days 4-7). Cravings fall sharply and become cue-driven rather than chemical. Lung cilia begin regenerating. Circulation improves measurably.

Phase 3 — Turning Point (Days 8-10). Cravings are rare and brief now, and most last under 3 minutes. Your brain is rewiring.

Phase 4 — Consolidation (Days 11-14). Nicotinic receptors downregulate toward baseline. The physical addiction is broken.

SOS breathing

When a craving hits, the SOS button launches a 60-second guided breathing exercise based on paced-breathing research. No articles to read, no community posts — just breathe. It works offline and it is never behind a paywall.

AFTER HOURS

Fourteen original audio stories, one unlocking each day, written for the hours when the craving is boredom rather than chemistry. Ten languages, each with its own fourteen — not translations of one another. They download only if you want them.
