Permille

Permille keeps track of what you drink – and how it affects you. Use the app only for alcohol, only for caffeine or for both. It adapts to you: if you drink coffee in the morning, you see the caffeine display. If you go out in the evening, you see the estimated blood alcohol value. If you do both, you see both side by side.

ALCOHOL AT A GLANCE
• Blood alcohol estimate based on the Widmark formula, with a traffic light and the estimated time until 0.0 ‰.
• The value rises gradually as you drink and falls off naturally – even past midnight.
• Water recommendation: the app shows how much more water would do you good and gently reminds you.
• When it gets to be a lot, you get tips for getting home safely.

CAFFEINE AT A GLANCE
• How much caffeine is in your body right now – calculated using the half-life, not just added up.
• When you can fall asleep easily again and when it has been fully broken down.
• Coffee, espresso, tea, cola, mate and the common energy drinks in the usual sizes.

FRIENDS ROUND
• With a six-digit code you are connected as a group – on vacation, at a festival or for one evening.
• You see each other's stamp cards, the estimated level and who is already home.
• "Look out for …": if someone's value rises sharply or quickly, the round gets a notification.
• Vacation timeline with all days of the round and a look back when it ends.
• A round with up to three people is free. With the group subscription or the permanent unlock, up to 20 people and several rounds at the same time are possible – one person pays, the whole round is included.

ALSO INCLUDED
• Daily totals: alcohol, caffeine, sugar, calories and costs.
• Mixer: put together your own drinks from an ingredient library and see all values instantly.
• Barcode scanner for drinks.
• History and statistics: curve of the evening, weekly and monthly values, spending and patterns.
• Stamp card, home screen widget and Health Connect integration.

IMPORTANT NOTICE
Alcohol and caffeine values are rough estimates, not a measuring device and not a diagnosis. Use at your own risk, without warranty. Never use them as a basis for driving – behind the wheel, 0.0 ‰ always applies. Not a substitute for medical advice. For adults only. Excessive alcohol consumption harms your health.
