Jittr: Cut Out Caffeine

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.

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.
