Permille

Your companion for the night: log fast, stay hydrated, keep your BAC in view — and tips for getting home safely. All local, no account.

Permille is your calm companion through the night: log drinks with a single tap, get gentle water reminders, keep your estimated blood-alcohol level in view — and when it gets heavy, tips for getting home safely. No competition, no encouragement — just overview and care.

WHAT IT DOES • Blood-alcohol estimate using the Widmark formula — with a traffic-light status and estimated time back to 0.0 ‰. • Daily totals: not just alcohol (g) but also sugar, calories and cost. • Water guidance: alcohol is dehydrating — the app shows how much water still helps and gently reminds you. • Mixer: build your own drinks from an ingredient library and see alcohol, sugar and calories live. • History & stats: your evening's BAC curve, weekly/monthly figures, spending and patterns. • Optional breathalyzer cross-check, Apple Health sync and Home/Lock-Screen widgets.

MINDFUL, NOT ENCOURAGING Permille is built for harm reduction: water, breaks and nutrition transparency come first. There is no ranking and no reward for drinking.

IMPORTANT The BAC value is a rough estimate, NOT a measuring device. Use at your own risk, without warranty. Never use it as a basis for driving — 0.0 ‰ always applies behind the wheel. It does not replace medical advice. For adults only. Excessive alcohol consumption harms your health.
