## Description

Know exactly when your last coffee is safe. Bio-Rhythm tracks caffeine in your system in real time, scores your sleep readiness, and tells you when to stop.

Still wired at midnight? Bio-Rhythm is the science-based caffeine tracker built for people who refuse to trade tomorrow's sleep for today's coffee.

Every coffee, tea, or energy drink you log is plotted on a real-time decay curve based on your personal metabolism. You'll see exactly how much caffeine is still in your system — and exactly when it will be safe to sleep.

— PROTECT YOUR SLEEP —
Get a precise countdown to your safe-sleep time. No more guessing whether that 3pm latte will haunt you at 1am.

— TRACK CAFFEINE IN REAL TIME —
Watch your caffeine level rise and fall on a beautiful decay chart, powered by the same exponential half-life formula used by sleep scientists.

— SCORE YOUR SLEEP READINESS —
Get a daily Bio-Rhythm Score from 0–100. Build streaks of "perfect nights" and see your 7-day trend at a glance.

— LOG ANY DRINK IN SECONDS —
27+ preloaded beverages — espresso, americano, matcha, Red Bull, Monster, 5-Hour Energy, Coke and more. Or add your own custom drink.

— HIT YOUR FOCUS ZONE (Premium) —
Smart dosing recommendations tell you exactly when to drink your next coffee for peak focus — and when to stop so your sleep is protected.

— BUILT FOR BIO-HACKERS —
Premium unlocks custom half-life (1–12 hours) and sleep sensitivity threshold (0–100mg) so the math matches your body, not an average.

— PRIVATE BY DESIGN —
All your data stays on your device. No accounts, no cloud, no tracking.

Stop sabotaging your sleep. Start tracking with Bio-Rhythm.
