Need help with 336? We're here for you.
How does 336 work?
Tap "I QUIT NOW" and the app tracks every hour of your 14-day nicotine detox. Each hour shows clinical data about what's happening in your body — nicotine clearance, receptor recovery, and symptom timelines.
Can I reset my quit date?
Yes. Go to Settings and tap Reset. You'll be asked to note what triggered the relapse. This is for your own awareness — the data stays on your device.
Does 336 work for cigarettes too?
Yes. 336 tracks nicotine withdrawal, which is the same whether you vape, smoke cigarettes, use pouches, or any other nicotine product.
Is 336 free?
Yes. 336 is completely free with no ads and no subscriptions. At the end of your 14-day sprint, you'll have the option to make a donation if the app helped you.
Is my data private?
Your quit date and all progress data are stored locally on your device. Nothing is sent to our servers. See our Privacy Policy for details.
