About this app

Sobr — know your blood alcohol, know when you're sober again. Built for Wear OS.

Most drink counters just add up glasses. Sobr does it properly: it estimates the alcohol actually in your blood with a Widmark-based model that follows both the absorption after each drink and the steady elimination by your liver, so the peak, the curve and the moment you're back under your threshold are realistic, not guessed.

At a glance you see your estimated BAC (‰) right now, exactly when you'll be under your personal threshold again, and how tonight compares with your daily limit. Log a drink in one tap and get a notification the moment you're sober.

FEATURES
• Live estimated BAC (‰) on a clean colour gauge, green to red
• Sober time — the moment your level drops below your threshold, in hours and minutes
• Curve graph with your limit and high-threshold zones, your drinks as points, and the projection ahead
• Today's drinks list with time, volume and strength; delete with a tap
• 7-day, 30-day and monthly statistics with bar charts, peak and 7-day average
• One-tap logging from presets (beer, wine, spirit, pint, cocktail, champagne…) or any volume and alcohol %, including drinks from minutes ago
• Notification the moment you're estimated to be under your threshold
• Morning-after recap: last night's peak, drinks and when you were sober
• Wear OS tile with your level, drinks against limit and sober time, straight from the watch face
• Everything runs on the watch: no phone, no account, no data leaves the device

MAKE IT YOURS
Set your body weight, sex, elimination rate, threshold, high threshold and daily limit — Sobr recalculates your personal curve instantly.

IMPORTANT
Sobr gives an estimate based on a statistical model. Individual differences are large. Never use it to decide whether you can drive, operate machinery or work — if you have been drinking, don't drive.

Know your number. Sobr.
Estimate your blood alcohol, see when you're sober again. Live on your wrist.
