## What is Jjan?

The same two drinks hit two people differently.
Jjan is a friend who understands your body and looks out for your health. While you drink, it shows how tipsy you are — based on your own body — as one simple color: green, yellow, or red. The next morning it takes care of your hangover, and week after week it keeps an eye on your rhythm. The more you use it, the better it gets to know you.

■ One tap, that's it
A shot, a pint, a glass of wine — log it the way you already drink, with a single tap. It works from the Lock Screen too, so your phone can stay in your pocket.

■ A personalized engine built on 16 medical studies
It starts with your sex, age, height and weight, then factors in how fast each type of drink is absorbed, and the gaps between glasses. The numbers come straight from the research — the Watson (1980) body-water formula, the Seidl (2000) regression for how alcohol distributes across different builds, Mitchell's (2014) measurements of absorption rates by drink type — plus published drinking guidelines.

The answer isn't a number — it's a single color: green, yellow, or red. One glance across a noisy table is enough.

■ It gets to know you
Each morning Jjan asks how you're feeling, and every answer fine-tunes how fast it thinks your body clears alcohol. You aren't the same person tonight that you were last Friday — and Jjan learns that as your check-ins add up.

■ A friend beside you while you drink
If your pace picks up, Jjan mentions it quietly and nudges you toward a glass of water. Go past the limit you set tonight and it won't lecture you — it just shows you the nights you stuck to your plan, stacking up.

■ The next morning, hangover care just for you
You get a look back at last night in a tone that never judges: which hours the drinks piled up in, whether you stayed green all the way.

Then it builds a recovery plan around both what you drank last night and how you feel this morning — not the same generic advice every time. And it's honest with you that what really works is time and rest.

■ When your liver clocks out
From your last drink, Jjan estimates the time left until the alcohol is fully cleared, using your build and how much you had. You can see at a glance whether your liver is still on the job.

■ Your rhythm, week by week
How many nights this week, how that compares to last month, how long your current streak of clean days is. Not numbers scolding you — just your body's own pattern, laid out.

■ The quiet exit
For nights that are hard to leave, one button gets you a phone call 30 seconds later. Pick the caller's name and voice in advance, or record your own. It all happens inside your phone — nobody is ever actually called.

■ Your records stay yours
Sign in with Apple and your drinking log is stored only in your own iCloud. Your records are never used for ads or marketing.

■ Premium
Unlocks tailored hangover care, the liver recovery timer, full-history rhythm analysis, Apple Watch, voice packs, and no ads.

The colors and recovery times are personalized estimates for general wellness only. They are not medical advice, and must never be used to decide whether it's safe to drive. For people of legal drinking age only. Please drink responsibly.
