About

Permille

Read full description

Permille keeps track of what you drink — and how it affects you. Use it for alcohol only, for caffeine only, or for both. It follows your lead: drink coffee in the morning and you see the caffeine reading. Go out at night and you see your blood-alcohol level. Do both and you see both, side by side. No competition, no encouragement — just overview and care. ALCOHOL IN VIEW • Blood-alcohol estimate using the Widmark formula — with a traffic-light status and estimated time back to 0.0 ‰. • The value rises gradually while you drink and comes down naturally — across midnight, too. • Water guidance: alcohol is dehydrating — the app shows how much water still helps and gently reminds you. • When it gets heavy, you get tips for getting home safely. CAFFEINE IN VIEW • How much caffeine is in you right now — calculated from its half-life, not just added up. • The answer that matters: when you can fall asleep well again, and when it has fully worn off. • A heads-up when you go past the 400 mg daily guideline. • Coffee, espresso, cappuccino, latte, cold brew, matcha, tea, cola, mate and the common energy drinks in the usual sizes — each with and without sugar. BOTH TOGETHER • Vodka Energy or an Espresso Martini? The app works out alcohol and caffeine separately from the same drink. • Worth knowing: caffeine masks tiredness, not the alcohol. The app says so whenever both are in play. • A coffee never counts as alcohol — your dry days and stamp card stay untouched. ALSO INSIDE • Daily totals: alcohol, caffeine, sugar, calories and cost. • Mixer: build your own drinks from an ingredient library and see every value live. • History & stats: your evening's curve, weekly and 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 Your entries are stored locally only. No account, no ads. Anonymous usage statistics (can be turned off) help improve the app. IMPORTANT Blood-alcohol and caffeine values are rough estimates, 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.
