See how much caffeine is in your body right now, know your last safe cup before bed, and log every coffee, tea or energy drink in seconds.
CoffeeLog turns every cup into something useful. Log your coffee, espresso, tea, energy drink or soda in seconds and instantly see how much caffeine is still active in your body.
Most caffeine apps are just a counter. CoffeeLog runs a real half-life engine that models how caffeine builds up and clears over the hours after each drink, shows a live "in your system right now" curve, and tells you the latest cup you can have before it cuts into your night.
WHAT YOU CAN DO
• Log in seconds from a built-in database of coffees, teas, energy drinks, sodas and pre-workout — each with caffeine in mg, or add your own drinks.
• Watch a live decay curve of the caffeine still active in your body, tuned to a half-life you can personalize.
• Get your last-cup-before-bed time so an afternoon coffee doesn't cost you sleep.
• Set a daily caffeine target and track your intake against it all day.
• Sync with Apple Health and bring in sleep data to see how your habits and your nights line up.
• Check today's total and what's still in your system from a home-screen widget.
• Review a clean history with weekly and monthly trends so you can cut back at your own pace.
PRIVATE BY DESIGN
CoffeeLog runs on your device. No account, no sign-up — your log stays with you.
Whether you want steadier energy, fewer jitters, better rest, or simply to know how much caffeine you really drink, CoffeeLog gives you the full picture.
