AfterSip -Know Your Metabolism

iOS Universel / Utilitaires

AfterSip helps you understand when caffeine and alcohol are still active, when they may clear, and how they can affect your target bedtime.

Instead of guessing whether it’s too late for another coffee or whether a drink is still carrying into the night, AfterSip gives you a cleaner timing view based on what you logged, when you logged it, and when you want to sleep.

Use AfterSip to:
- Track caffeine and alcohol in one place
- See caffeine cutoff guidance based on your target bedtime
- Estimate when alcohol may clear
- View clear timing curves and recent intake history
- Save custom drinks with amount and volume
- Export a simple timing report
- Optionally write caffeine entries to Apple Health

Built for real life:
Log espresso, americanos, lattes, tea, energy drinks, beer, wine, cocktails, and your own custom presets. AfterSip is designed to make quick decisions easier, whether you are trying to protect sleep, avoid stacking too much caffeine, or better understand how long alcohol may still be active.

Why people use AfterSip:
- To avoid late caffeine that pushes sleep later
- To better judge the timing impact of drinks across the day
- To keep a simple record without spreadsheets or guesswork
- To get a more thoughtful view than a basic intake tracker

Private by design:
Your data stays on your device. AfterSip does not require an account, does not use third-party tracking, and keeps the experience focused on fast logging and practical timing guidance.

Important:
AfterSip is a timing aid, not a medical, emergency, or driving-safety tool. Alcohol and caffeine responses vary by person. If you feel impaired, do not drive.

AfterSip — Know What's Still In You
Ever wonder how much caffeine is still buzzing through your system hours after that last espresso? Or when you'll actually be sober enough to drive?
AfterSip answers these questions with real science, wrapped in a gorgeous 1930s-inspired design that makes health tracking genuinely fun.

REAL-TIME METABOLIC TRACKING
AfterSip isn't a simple drink counter. It uses pharmacokinetic models — the same math used in clinical research — to predict exactly how caffeine and alcohol move through your body in real time.
- Two-Compartment Model for caffeine: tracks absorption, peak levels, and elimination curves unique to your metabolism
- Widmark-Watson Model for alcohol: calculates your BAC and projects when you'll be completely clear
- Interaction modeling: understands how caffeine and alcohol compete in your system simultaneously
Watch your levels rise and fall on beautiful kinetic charts that forecast hours into the future, complete with crash warnings and projected clearance times.

SMART HEALTH INSIGHTS
AfterSip goes beyond numbers to give you actionable intelligence:
- Caffeine Risk Engine evaluates your intake across three dimensions: daily total, single dose size, and bedtime residual
- Estimated Sleep Latency tells you exactly how many extra minutes caffeine will keep you awake tonight
- Lifestyle Protocols adapt the app to your situation — whether you're pulling an all-nighter (Zombie Protocol), resetting caffeine tolerance, enjoying a
date night, or battling jet lag
- Caffeine Calibration helps you discover if you're a fast, average, or slow metabolizer
- HealthKit integration syncs your data seamlessly with Apple Health

YOUR VIRTUAL BACKYARD

This is where AfterSip gets truly unique. Every drink you log materializes as a tiny cup or bottle in your personal backyard — a charming, interactive scene complete with a cottage, garden, and a pet companion that reacts to your metabolic state.

But your backyard isn't just for show. It's a complete economy:
- Cups and bottles line up neatly on shelves and crates beside your cottage
- Recycle 5 cups or 5 bottles to earn coins
- Spend coins in the Shop to decorate your home with 12 unique items: flower pots, wind chimes, lanterns, garden gnomes, bird baths, fountains, and more
- Watch your backyard transform through dynamic sky phases — dawn, day, dusk, and night — all rendered in hand-drawn 1930s style
The more you track, the more your backyard grows. It's a gentle, rewarding loop that makes logging drinks feel less like a chore and more like tending a garden.

1930s JAZZ CLUB AESTHETIC
Every pixel of AfterSip is crafted in the style of 1930s animation and vintage jazz club posters. Think Cuphead meets a speakeasy:
- Thick ink outlines and hand-drawn borders
- Warm parchment backgrounds with watercolor washes
- Stage Gold for caffeine, Smoky Blue for alcohol, Neon Coral for warnings
- Georgia Bold headlines paired with clean Avenir Next body text

Your virtual companion — Eddie Vale or Lottie Bell — delivers contextual advice with period-appropriate charm, reacting to whether you're wired, winding down, or somewhere in between.
