See progress you can feel
Turn abstract commitment into a visible streak. Every day smoke-free is a specific number — savings, cravings avoided, milestones reached.
Quit smoking tracker · iPhone
Quit smoking, tracked simply.
Blou turns your quit into something you can see — streak, savings, cravings, and recovery milestones — so you stop relying on willpower alone. Free on the App Store.
Visual streaks & milestones
Money saved & lung recovery
Craving timer with short actions
Why a tracker works when willpower doesn't
Most quit attempts fail in the first two weeks — not because people lack motivation, but because the craving-response loop is invisible. Blou makes it visible so you can interrupt it.
Plan, don't willpower
Pre-commit a 2-minute action for each of your top cravings. The app nudges you through the first 3–5 minutes, which is all most cravings last.
Recovery timeline, not vague promises
Know what's typically happening in your body day 1, day 3, week 1, and beyond — backed by NHS, CDC, and Surgeon General public guidance.

Frequently asked questions
Is Blou free to use?
Yes. Blou is free to download on the App Store. Core tracking features — streak, money saved, cravings, milestones — are free. Optional premium features support ongoing development.
Where should I start if I want to quit smoking?
Start with our free step-by-step guide at /how-to-quit-smoking, set a quit date within the next 7–14 days, and line up one form of evidence-based support (NRT, varenicline, bupropion, or free quitline coaching).
What happens to your body after you quit smoking?
Recovery begins within hours and compounds for years. See our milestone guides from 1 day to 10 years smoke-free for timelines based on CDC and Surgeon General public summaries.
How long do nicotine cravings last?
Each individual craving typically lasts 3–5 minutes. Physical nicotine withdrawal peaks on days 2–3 and fades over 2–4 weeks. Cue-based urges can appear for months but become much less frequent.
Is Blou available on Android?
Not yet. Blou is iPhone-only today. Join the Android waitlist on this page and we'll let you know the day it launches.
Is this website medical advice?
No. Blou content is for general education and motivation. It does not replace advice from a qualified clinician. If you have a medical condition or take prescription medication, talk to your clinician when making changes.
