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.
YOUR DATA STAYS WITH YOU
Everything is stored locally only. No account, no tracking, no ads.
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.
