Caffeine Flow:Caffeine Tracker

Caffeine Flow is an intelligent caffeine management app that tracks your body's caffeine levels in real time using half-life pharmacokinetics and guides you to the optimal bedtime for uninterrupted sleep.

Log your daily caffeine intake from coffee, energy drinks, tea, and soda with ease, and visualize how caffeine flows through your body throughout the day.

Science-Based Caffeine Tracking
Using the caffeine half-life formula, Caffeine Flow precisely calculates your current body caffeine level. Instead of simply tallying intake, it shows how your actual body concentration changes over time with intuitive visual graphs.

Sleep Safe Time & Risk Warnings
By combining your bedtime settings and caffeine sensitivity profile, the app pinpoints exactly when you should stop consuming caffeine and when it is safe to fall asleep. Intuitive warnings appear on your home screen if you exceed daily limits.

Personalized Caffeine Profile
A quick sensitivity quiz analyzes your metabolism type (Elephant, Human, or Rabbit). Factoring in your weight and special conditions, it automatically calculates your personalized daily caffeine limit.

Expanded Asian & Global Drink Database
Preloaded with data from major franchises across Asia and global brands. We now support official brand-specific cup sizes (e.g., Tall, Venti) for accurate logging.

Weekly & Monthly Deep Insights
Go beyond basic charts. Our new Deep Insights feature analyzes your sleep interference index, recommended cutoff times, and dependency trends with comprehensive weekly and monthly reports.

Intuitive Dashboard
View today's total intake, current body level, remaining daily allowance, and sleep safe time all on one screen.

Home Screen Widgets
Check your current caffeine level and estimated sleep readiness time directly from your home screen without opening the app.
