Halen: Quit Smoking Tracker

Quit smoking by cutting down first — with a plan that recalculates itself instead of punishing you. Halen is a private, on-device quit-smoking companion: • ONE-TAP LOGGING — a single big button, a home-screen widget or a quick-settings tile. Logging takes a second, so you keep doing it. • ADAPTIVE REDUCTION PLAN — the daily budget shrinks step by step. Went over today? Halen just says "we recalculated" and spreads the rest of the day. No guilt. • HONEST NUMBERS — modelled nicotine, carbon monoxide and particle load curves built from your own timestamps, always labelled as models. Every formula is published inside the app: "How is this calculated?" • TWO SIMPLE SCORES — a Progress Score for what you are doing, and a Harm Load for what your body is carrying. Both show their full workings; the load falls as you cut down. • CRAVING WINDOW — Halen learns the hours you usually reach for one, tells you what has actually worked for you before, and can give you a heads-up twenty minutes ahead (off by default). • HEALTH TIMELINE — WHO-based milestones, from 20 minutes to 15 years, plus a body map where every harm card ships a recovery card. • MEDICINES THAT WORK — the thing most quit apps leave out. What nicotine replacement, varenicline and bupropion actually do, how they are used, the mistake that wastes them, and their published effect sizes. No brands, no doses, no sales — just what to ask a pharmacist. • A DATE, AND A PLAN FOR IT — set a quit date, count down to it, and get the first day laid out from morning to night. A plan for your own high-risk moments, written before you are in one. • ONE SLIP IS NOT THE END — Halen names what happened and tells you the next move. No blame, but no silence either. • CRAVING SOS — one toolkit, every technique graded by evidence: a five-minute walk (strong), paced breathing, delay and water (promising), ear acupressure (traditional, needle-free, and we say plainly that the long-term evidence is not there). "I resisted" counts your wins; "I smoked" logs and adapts — no shame. • WHAT SMOKING COSTS — your all-time total (years x cigarettes x price), today, 7 days, 30 days and 12 months in your own currency, and today against your usual day. No made-up savings: money counts only for finished days you actually logged. Log every pack you buy from the home screen in one tap; costs follow the prices you really paid. • YOUR DATA STAYS YOURS — no account, no Halen server, no analytics. Encrypted on device, excluded from backups, export anytime. • FREE FOREVER TIER — unlimited logging, savings, day counter, 7-day chart and export. Premium (one-time, lifetime) unlocks the adaptive plan, full charts, trigger patterns, the complete timeline and SOS toolkit, and removes ads. ADS, HONESTLY: the first 7 days are a full, ad-free trial with no card. After that the free version shows one small, clearly labelled Google AdMob banner above the bottom bar, only with your consent where the law requires it — never during an SOS, never using your smoking data. Premium is one small one-time purchase, not a subscription. This app is not medical advice. For the treatment of nicotine dependence, consult a health professional. If you are pregnant, or have a heart condition or a psychiatric condition, seek expert advice first. Quit lines: pick your country from a searchable list of 250 — official numbers from the WHO list and national health services.
