Extinct: TSM Alcohol Tracker

A companion app for the Sinclair Method: log your drinks, keep the Golden Rule, and watch your own trend over time. Extinct is the dedicated companion app for adults following The Sinclair Method — using naltrexone or nalmefene taken before drinking to gradually extinguish the craving for alcohol. Built by someone who has lived the TSM journey. No judgment. No abstinence pressure. Just the tools to see it through. NOT MEDICAL ADVICE Naltrexone requires a prescription. Never take it if physically dependent on opiates. Extinct supports your journey — it does not replace your doctor or prescriber. THE GOLDEN RULE — ALWAYS FREE The most important feature in the app. Never paywalled. The standard protocol is to take your medication 1–2 hours before drinking. Set your wait time with your prescriber — the right timing varies from person to person. Enter it in Extinct and it walks you through the full planning flow: medication reminder, countdown timer, and confirmation before your first drink. The Golden Rule is everything in TSM and Extinct makes sure you never forget it. DRINKING DIARY Log every session with drinks from a 4,400+ beverage catalog scoped to your country, ABV, volume, mood, and medication confirmation. Unit calculations in both UK and US standard drinks. 30 sessions per month free, unlimited with Pro. 4,400+ DRINK CATALOG Real drinks TSM users actually drink — beers, wines, spirits, and ciders. Not a cocktail app. Custom drink entry for anything not in the catalog. Country selector at setup. STATS DASHBOARD — FREE Your progress at a glance: this week's drinks vs your baseline, reduction percentage, naltrexone compliance rate, current streak, longest alcohol-free streak, and your lowest week so far. MILESTONES Achievement badges for real clinical checkpoints — first alcohol-free day, compliance streaks, 25% and 50% reduction, and more. AI REFLECTIONS Optional. A weekly read of your own extinction curve, and a reflection on your own journal entries. They summarise what you have already logged — they do not answer questions about medication, dosing or timing. Those belong with your prescriber. RESOURCES 988, SAMHSA National Helpline, Options Saves Lives, r/Alcoholism_Medication, C Three Foundation, and how to find a TSM-knowledgeable doctor. PRO FEATURES ($4.99/month or $34.99/year) Extinction Curve — your actual weekly drinks plotted against Sinclair's expected extinction curve. The curve is what the method predicts in general, not a forecast for you. Craving (VAS) History — track your Visual Analog Scale craving scores over time, alongside your drink count. Weekly AI Interpretation — a warm, plain-language read of the week you logged: patterns and compliance, reflected back to you. Unlimited Diary Logging — remove the 30-session monthly cap entirely. Selective Extinction — healthy reward activities on non-drinking days, with receptor supersensitivity notifications. Reflection Journal — daily TSM-specific prompts, free text journaling, weekly AI theme analysis, and PDF export for your therapist or sponsor. Trusted Person Sharing — share a read-only progress summary with a partner, family member, or sponsor. Includes a TSM explainer so they understand why drinking is part of the treatment. Physician Report — a 4-page PDF for your doctor: extinction curve, compliance, session summary, and a TSM overview. YOUR DATA No ads, ever. Cloud sync via Firebase when signed in. AI features transmit only your session inputs — no name, email, or device ID. Never used for model training per Anthropic's enterprise terms. Extinct is a companion app for people following the Sinclair Method under the care of a prescriber. It records what you log and reflects it back to you. It is not a treatment, it does not give medical advice, and it is not a substitute for the clinician who prescribed your medication. Not medical advice. If you are in crisis, call 988 or SAMHSA at 1-800-662-4357.
