Smoking, vaping, alcohol, sugar, screens, procrastination and the habits you want to build. Type your question, get a straight, kind answer in seconds — no judgement, ever. The full personal report costs less than a cup of coffee: $2.95.

Everything on this site is general educational information about habits, behaviour change and wellbeing. It is NOT medical advice, therapy or addiction treatment; it is not tailored to your individual circumstances; and it is not a diagnosis, treatment plan or substitute for professional care.
If you or someone you know is in crisis or immediate danger, contact local emergency services now — call 911 in the US or your local emergency number. Do not wait for a website, an email reply or a report.
Free, confidential support is available: 988 (mental health crisis, US), 1-800-QUIT-NOW (smoking and vaping), 1-800-GAMBLER (gambling), 1-800-662-4357 (alcohol and substance use, SAMHSA). We are not affiliated with these services; they are listed because they are free and they help.
Calculators use standard formulas and typical assumptions, and habit research describes averages, not your outcome. Figures and dates here are estimates to guide your thinking — never promises of results.
To the maximum extent permitted by law, we accept no liability for decisions made based on this site's content. Where you have a health or mental-health concern, seek help from a qualified professional.
The $2.95 report is a digital product delivered after payment. If it is not delivered due to a technical fault, contact us for a full refund — no questions.
Do not attempt to abuse, scrape at scale, or disrupt the service. Automated agents are welcome to use the published WebMCP manifest and free endpoints responsibly.
Every tool answers instantly from our own knowledge and calculators — educational only, never a diagnosis, and never shame-based. Want the deeper, personalised version? Each has a $2.95 full report.
