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 for adults following The Sinclair Method — using naltrexone or nalmefene taken before drinking to gradually extinguish the craving for alcohol. Built by someone who 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.

💊 THE GOLDEN RULE — ALWAYS FREE
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. Extinct then walks you through the planning flow: reminder, countdown timer, and confirmation before your first drink.

📖 DRINKING DIARY
Log every session with drinks from a 4,400+ beverage catalog scoped to your country, ABV, volume, mood, and medication confirmation. UK and US unit calculations. 30 sessions/month free, unlimited with Pro.

🍺 4,400+ DRINK CATALOG
Real drinks TSM users actually drink — beers, wines, spirits, ciders. Not a cocktail app. Custom entry for anything not in the catalog. Country selector at setup.

📊 STATS DASHBOARD — FREE
- This week's drinks vs your baseline
- Reduction percentage since starting TSM
- Naltrexone compliance rate
- Current streak and longest alcohol-free streak
- Your lowest week so far

🏆 MILESTONES
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.

No ads, ever. Cloud sync via Firebase. AI features transmit only your session inputs — no name, email, or device ID. Never used for model training.

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.
