Jitterbug: Caffeine Coach

Quit less. Taper smarter.

Most caffeine apps help you drink more efficiently. Jitterbug helps you need less.

Meet your AI caffeine coach — the only app that builds you a personal taper plan, forecasts how tonight's coffee will affect your sleep, and tracks your progress through a visual journey you can actually feel.

WHY JITTERBUG
You don't want to quit caffeine. You want LESS of it. Jitterbug builds you a personal reduction plan that adapts to your habits, week by week. No willpower required. No cold turkey.

WHAT'S INSIDE
• Real-time tracker — every drink, every milligram, all day
• Sleep forecast — see how tonight's coffee will hit your sleep, before you order it
• AI taper plan — gentle, moderate, or aggressive — your pace, your timeline
• Drink scanner — point your camera at any coffee, energy drink, or supplement (Open Food Facts + USDA FoodData Central + AI vision)
• Monthly tooth journey — five stages mark your progress (Stage 1 stained → Stage 5 sparkling)
• Apple Health sync — caffeine alongside sleep, heart rate, and workouts
• One-tap log — recents + your saved library, ready in a tap
• Smart cutoff alerts — quiet reminders before your sleep window closes

THE SCIENCE
Caffeine has a half-life of three to nine hours depending on genetics, hormones, and lifestyle — which is why a 2pm coffee wrecks one person's sleep and not another's. Jitterbug learns your personal curve and forecasts how every milligram will land.

JITTERBUG PRO
Unlock unlimited drink scans, deeper sleep forecasts, and your full Hall of Fame — your longest streaks, ranked all-time. Available weekly, monthly, or lifetime.

PRIVACY
Your caffeine data stays on your device. Apple Health sync is write-only — we never read your other health data.

Made for people who love coffee enough to drink it better.
