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.
