Extinct: TSM Alcohol Tracker

The Sinclair Method works. Extinct helps you prove it.

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. Set your medication type (naltrexone: 1 hour wait, nalmefene: 2 hours) and Extinct 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 estimated weeks to extinction.

MILESTONES
Achievement badges for real clinical checkpoints — first alcohol-free day, compliance streaks, 25% and 50% reduction, and more.

AI CONSULT
A TSM-trained AI companion. Ask anything about the method, missed doses, side effects, or how to explain TSM to your doctor. 5 messages per month free. Unlimited with Pro.

RESOURCES
