Description
Sobrium keeps you in control of your phone when you're not in control of your judgment.
Switch on Alcohol Mode before going out. The apps you'd regret using — Phone, Messages, WhatsApp, Telegram, Signal, Instagram, Snapchat, anything you choose — get locked at the system level. Tap one and you'll see a shield: take a quick sobriety test to unlock everything for the duration you set.
WHY SOBRIUM
Most "drunk lock" apps are just a button you can disable in two taps. Sobrium uses Apple's Screen Time framework to lock apps the same way parental controls do — strong enough that even drunk-you can't easily bypass it.
FOUR SOBRIETY TESTS
Sobrium picks one at random when you try to unlock:
Color Match — A reaction-time test based on the Stroop effect. The word "RED" appears in blue ink. Tap the color, not the word. Alcohol slows the brain's conflict-resolution; this is the strongest cognitive signal of impairment.
Tap Rhythm — Watch a beat for a few seconds, then keep tapping the same tempo without the cue. The cerebellum handles timing precision, and alcohol hits it hard.
Steady Trace — Drag your finger along a curved path. Measures fine motor control — the same skill roadside tests check.
Stand Still — Hold the phone against your chest and balance on one leg. The accelerometer measures your sway, just like the police one-leg-stand test.

PRIVACY FIRST
Sobrium runs entirely on your device. No accounts, no cloud, no tracking, no analytics. The app never sees what you're typing or who you're calling — it only knows whether the apps you chose are currently locked.

REQUIREMENTS
iPhone with iOS 17 or later
Screen Time / Family Controls permission (granted on first launch)
A NOTE ON RESPONSIBILITY
Sobrium is a behavioral tool, not a medical device. It cannot measure your blood alcohol level — it measures coordination, reaction, and balance, all of which alcohol affects. If you're impaired, please don't drive. Call a cab, call a friend, get home safe.
