The session screen

One screen carries the whole night

Log a drink and Abvy keeps the picture up to date: where you are, where the evening is heading, and when the next one is fine. Here is what each part of it does.

The session readout: 0.39 per mille
Your level Right now, estimated from what you logged and when.
The BAC curve with drink markers, the peak at 21:45, and sober at 01:14
The curve Pours, the peak, and your sober window, hour by hour.
Insight rows: under your limit and coming down, next red wine right now, fully sober in 3½ hours
What comes next When the next one keeps you under your line, and when you are clear.
The quick-log bar: red wine, water, food, add
Quick bar Your usual pour, water and food, one tap away.

The honest bit.

No - nothing on your phone can measure your blood. Abvy estimates from what you log: your drinks, your body, the clock. That's why every number wears a little squiggle, and why the sober time is a window, not a promise.

Know where you stand.

Estimates only, never a verdict. Abvy is not a breathalyzer and is no substitute for judgment: if you drink, don't drive.
