You know the jitters. The 3 PM crash. The midnight ceiling-stare wondering why you can’t sleep. Jittr shows you exactly what caffeine is doing to your body — and gives you a plan to take back control. Jittr is the first caffeine reduction app built for how you actually drink. Log your Celsius, Monster, Starbucks, Dunkin’, boba, or pre-workout in one tap. Then watch your real-time metabolism curve show you exactly how much caffeine is still in your system — and when you’ll be sleep-ready tonight. This isn’t another generic tracker. Jittr is a caffeine coach that builds you a personalized tapering plan to cut back gradually — no cold turkey, no withdrawal headaches, no willpower required. WHAT YOU GET FOR FREE: • Quick-log 300+ drinks Gen Z actually buys — Celsius, Red Bull, Monster, Starbucks, Dunkin’, Dutch Bros, Ghost, Alani Nu, boba, pre-workout, and more • Real-time caffeine metabolism curve showing your current levels and a live “sleep-ready” countdown timer • “What if?” simulator — see how your next drink shifts your bedtime before you buy it • Daily caffeine budget ring with color-coded progress • 7-day drink history UNLOCK JITTR PREMIUM: • Personalized Tapering Plan — a week-by-week step-down schedule that auto-adjusts to your pace. The app does the math so you don’t have to. • Sleep Quality Dashboard — log your sleep each morning and watch Jittr build your personal caffeine-sleep profile. Discover exactly when YOUR caffeine cutoff should be. • Smart Cutoff Notifications — get a push alert at your personalized caffeine cutoff time every day. • Streak System with Streak Insurance — track consecutive days under your goal. Premium members get streak freezes so one bad day doesn’t erase your progress. • Withdrawal Tracker — log symptoms, see a forecast of when they’ll peak and resolve, and stay motivated through the hard part. • Drink Swap Suggestions — Jittr recommends lower-caffeine alternatives for your favorite drinks so you can cut mg without cutting the ritual. • Barcode Scanner & Photo Snap — scan a can or snap a photo and Jittr identifies the drink and caffeine content instantly. • Unlimited History, Advanced Analytics & Shareable Reports — export your 30-day caffeine reduction card for Instagram Stories. PRICING: Free with optional premium upgrade. 7-day free trial included. • Monthly: $5.99/mo • Annual: $29.99/yr (save 58%) • Lifetime: $49.99 one-time purchase BUILT ON SCIENCE: Jittr’s metabolism curve uses caffeine’s pharmacokinetic half-life (5–7 hours) to estimate blood levels over time. Research shows residual caffeine degrades deep sleep architecture even when you feel like you slept fine. Jittr makes the invisible visible. Whether you’re trying to quit energy drinks, cut back on coffee, or just figure out why you can’t sleep — Jittr gives you the data and the plan. No judgment. Just results.
