CaffIQ: Caffeine Tracker

See how today's coffee becomes tonight's sleep — and how late you can still enjoy your next cup, tuned to your body. Real-time tracking, smart timing. 7-day free trial.

Love your coffee. Keep your nights.

You don't have to choose between the coffee you love and the sleep you need. CaffIQ shows you how today's coffee, tea, and energy drinks turn into tonight's sleep — and exactly how late you can still enjoy your next cup, tuned to your own body.

It was never the coffee. It's the timing.

WHAT MAKES CAFFIQ DIFFERENT

→ Tuned to YOUR body Most caffeine apps use one-size-fits-all averages. CaffIQ adapts to your weight, age, and sensitivity for predictions that reflect how caffeine actually clears in your system.

→ See your last cup, before you pour it A real-time readiness score tells you how late you can still enjoy a coffee and protect tonight's rest. No guesswork. No 2 a.m. ceiling-staring.

→ Track in real time, everywhere Live Activities show your current caffeine level on the Dynamic Island and Lock Screen. Glance at Home Screen widgets. Ask Siri "When can I sleep?" — get an instant answer.

GROUNDED IN RESEARCH

CaffIQ's timing is informed by peer-reviewed sleep science — translated into clear, everyday guidance (no PhD required). Caffeine's half-life varies widely from person to person, so a generic "stop at 2 p.m." rule rarely fits. CaffIQ does the math for you.

MADE FOR

→ Coffee lovers who don't want to give it up — just understand their cup → Busy people who want to perform by day and sleep at night → Anyone who feels wired or jittery and wants to stay in control → People keeping caffeine under a personal limit, tuned to their body → Anyone who's ever lain awake wondering "was it the afternoon latte?"
