About this app

BarNight is your night-out companion. From pre-drinks at home to the club closing, it keeps the thread of your night so you can enjoy it without losing track.

Create your account and you're off, solo or with your mates.

▸ COUNT YOUR DRINKS IN ONE TAP
One tap per drink. Total, average and budget calculated automatically. "Same again" to repeat, "undo" if you slipped.

▸ YOUR STATE, IN REAL TIME
An estimated blood alcohol level (Widmark model) updated with every drink, always in view. Caffeine tracking too. A "driver mode" with strict thresholds. BarNight is not a breathalyser and will never tell you that you can drive: the estimate is indicative, safety comes first.

▸ CHAIN THE PLACES
Pre-drinks at home, a bar, a mate's place, a restaurant, the club: everything stays on the same thread. Your drinks, your spending and your blood alcohol carry over from place to place, without resetting to zero.

▸ SPLIT THE BILL
Who paid what, who owes how much, with a photo of the bill to back it up. No more end-of-night maths.

▸ TOGETHER, LIVE
Invite your mates with a link: everyone follows the same moment, in real time.

▸ PLACES & BEERS
Your spots and everyone else's: prices, opening hours and the beers on tap, voted by the community.

▸ AND MORE
- "I'm drunk": BarNight learns your personal threshold and warns you before you get there.
- Memories: the memorable quotes and anecdotes of the night, kept for the morning after.
- Morning-after recap, with your residual blood alcohol until you're back to zero.
- Got home safe: one tap at the end of the night to reassure your mates.
- Party games, stats and history, optional smoker profile.
- Works offline: your drinks log without signal and sync when you're back.

Designed for your phone, in the dark, after a few drinks. Simple, fast, readable.

Alcohol abuse is dangerous for your health; please drink responsibly. Never drive after drinking. BarNight is an informational and social tool: the blood alcohol shown is an estimate and is not medical advice nor an official measurement.
