336: Quit Smoking & Vaping
Cold Turkey Vape & Nicotine
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Free 3-day trial — clinical hour-by-hour withdrawal tracker. Quit smoking or vaping cold turkey, with audio briefings tuned to your phase. No NRT, no gimmicks.
336 hours. That's how long it takes to break free from nicotine — completely, clinically, permanently.
336 is a cold turkey quit smoking and vaping app built on clinical science, not motivational fluff. Every hour of your 14-day detox is mapped with real pharmacological data: what nicotine is doing in your body, what withdrawal symptoms to expect, and exactly when they peak and fade.
NO NICOTINE REPLACEMENT. NO PATCHES. NO GIMMICKS.
This app is for people who are done. You quit, and 336 tracks your body's recovery hour by hour.
HOW IT WORKS
• Tap "I QUIT NOW" and your 336-hour countdown begins
• Each hour shows clinical data: nicotine blood levels, CO clearance, receptor recovery, and neurotransmitter normalization
• Track your progress through 4 distinct phases of 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 4 PHASES
Phase 1 — Acute Withdrawal (Hours 1-72): Nicotine leaves your blood within 48 hours. Carbon monoxide clears in 24. These are the hardest hours, and 336 walks you through every one.
Phase 2 — Peak Symptoms (Days 4-7): Cravings peak but your body is already healing. Lung cilia begin regenerating. Circulation improves measurably.
Phase 3 — Turning Point (Days 8-10): Withdrawal symptoms drop significantly. Most cravings last under 3 minutes. Your brain is rewiring.
Phase 4 — Consolidation (Days 11-14): Nicotinic receptors have downregulated. The physical addiction is broken. You are clinically free.
SOS BREATHING
When a craving hits, the SOS button launches a 60-second guided breathing exercise clinically proven to reduce acute nicotine cravings. No articles to read, no community posts — just breathe.
