Your night
has a shape.
SipWiser is a live blood-alcohol tracker: log each sip, watch your curve climb, and see the night's turn coming — before you take it. This page is one night. The gold line is you.
One tap when it lands in your hand.
No forms, no math, no judgment. Pick the drink, confirm the size — logged. It works with zero signal, in a loud bar, with one thumb.
The line just moved. That was you.
Watch the science, live.
Every sip absorbs on its own curve. Your liver clears at one steady, patient rate. SipWiser runs the real pharmacokinetics — the Watson formula, your body, your timing — and turns it into one honest line.
Computed on-device · offline-first · yours.
The turn you can
see coming.
Every night has a moment where one more stops being fun.
Most people find it the morning after.
You just watched it approach — in gold, from a hundred pixels away.
Tonight, the next drink didn’t happen.
The rest is chemistry.
From here, no app can hurry you and no coffee can either. Your liver clears roughly one drink an hour — a flat, honest rate. SipWiser simply counts it down.
SOBER ESTIMATE · 0.00 BY 06:42
Nobody opens an app at 2 a.m.
So the curve comes to you. A Live Activity on the iPhone lock screen. An arc on the Wear OS watch face. Glance, pocket, good night.
Right on time. The line remembers so you don’t have to.
One night is a story.
Thirty are a pattern.
Morning shows you the whole shape — what you drank, when it peaked, how it compares. Weeks become heatmaps. Limits become streaks. Dry challenges get a real finish line.
The shape you just scrolled — the way the app draws it.
SipWiser is built to help you drink less, never more. No streaks for drinking. No confetti for a big night. Just the shape of things, drawn honestly.
Know your curve.
Free, offline-first, and private — your nights never leave your hands unless you sync them.
Android · Wear OS · iPhone coming soon
Common questions
How does SipWiser estimate blood alcohol?
With real pharmacokinetics: the Watson formula uses your body data, each drink you log absorbs on its own curve, and your liver clears alcohol at a steady rate. It's a live BAC estimate, computed on your phone — not a measurement.
Can it tell me when I'll be back to 0.00?
Yes. SipWiser projects your sober time from your curve — "0.00 by 06:42" — and counts it down on your lock screen and watch while you sleep it off.
Does it work offline?
Fully. Every sip is logged and every calculation runs on your device. No signal needed in the bar, no account needed at all — sync is optional.
Which platforms does it run on?
Android and Wear OS today, with a lock-screen Live Activity and iPhone app coming soon. It's free.
Is a BAC estimate safe to drive on?
No. An estimate is never a green light — never drive after drinking, whatever any number says. SipWiser exists to help you drink with awareness, and less.
