Nightcap
A drink tracker for adults who want an honest picture of their drinking, whether they are cutting back or just keeping track.
Track it honestly, then get on with your night.
Log a drink in seconds
Tap a drink you have had before or type what you had, check the card and log it. Every drink is converted to your country's standard drinks or units.
An honest estimate
An estimate of your blood alcohol over the night, worked out with the Widmark formula and your own body profile. It can be wrong in either direction, it is not a breath test and it is never a time to drive. If you are driving, do not drink.
Two modes, no lectures
Drink less sets a weekly limit, counts alcohol-free days and shows the money you keep. Track freely is just your data, with no targets.
Crews that cheer the good stuff
Private groups you join with an invite code. Boards rank only alcohol-free days, streaks and water, never who drank the most. In a live session, sharing your estimate is opt-in and you can switch it off at any time.
Streaks and water
Count your alcohol-free days, log water alongside your drinks and do a 30-second morning check-in. Every night sits in a calendar.
Private by design
Your log lives on your phone and an account is optional. Analytics are off unless you switch them on. No ads and no ad trackers.
Most of it is free for good.
Free
Unlimited logging, the estimate, check-ins, crews, live sessions, widgets and the last 60 days of your record.
