Quit21

QUIT21 — 21 Days. One Decision. A Healthier Life.

Quit21 is a private, offline smoking-cessation companion built around one purpose: help you stop smoking and stay smoke-free.

YOUR QUIT, YOUR PACE A calm onboarding helps you understand your own smoking pattern and triggers, then you choose your quit date — now, tomorrow, or a date you pick.

LIVE SMOKE-FREE TIMER See exactly how long you've been smoke-free, and which of the 21 focus days you're on.

CRAVING SUPPORT, WHEN YOU NEED IT One tap opens a calm, personalized intervention — breathing, a short walk, or a plan matched to what triggered the craving — and a guided timer to get through the moment.

NO SHAME IF YOU SLIP If you smoke, Quit21 never says you failed. It helps you understand what happened, and get back to your plan — your previous smoke-free streak is never erased.

YOUR HEALTH JOURNEY A recovery timeline sourced from CDC/WHO guidance shows how your body can begin recovering over time — described honestly, with no guarantees, because everyone's recovery is different.

21 DAYS, THEN STAY QUIT 21 days is not a magic number — it's a focused period where Quit21 helps you practice living without cigarettes, day by day. After Day 21, Quit21 shifts to helping you protect what you've built: 30, 60, 90 days and beyond.

PRIVATE BY DESIGN No account. No login. No ads. No data collection. Your quit journey stays on your device — it's never uploaded anywhere, because there's no server to upload it to.

ONE-TIME PURCHASE Quit21 is a single, one-time purchase. No subscription, ever.

Quit21 is a behavioral support tool, not a medical device. It does not diagnose conditions or prescribe medication. Please consult a healthcare professional about your own situation.
