Caffeine Tracker - SipLog

Know when your caffeine wears off.

SipLog tracks every coffee, tea and energy drink and estimates how much caffeine is still in your system right now. See the curve for your day, how far you are into your daily guide, and the time you'll be sleep-ready.

LOG IN ONE TAP
• Tap a drink to log it, or touch and hold to change the size or time
• Undo straight away if you tap the wrong one
• Search a library of coffees, teas, sodas and energy drinks, or enter any amount
• Save your usual order with its exact caffeine

KNOW WHEN YOU'LL SLEEP
• A live estimate of caffeine in your system, based on its half-life
• Your sleep-ready time, and how each drink would change it before you log it
• A cut-off reminder before the last time a coffee will wear off by bedtime
• Set your own daily guide, bedtime, half-life and sleep-ready level

WIDGETS AND LIVE ACTIVITY
• Home Screen and Lock Screen widgets showing caffeine now and when you'll be sleep-ready
• Log your usual drinks straight from the widget
• A Live Activity counts down to sleep-ready on your Lock Screen and in the Dynamic Island

SEE YOUR PATTERNS
• Daily, monthly and yearly trends against your guide
• Caffeine still active at bedtime and when you usually have your last drink
• See how caffeine affects your sleep, using sleep data from Apple Health
• Export your history as CSV

PRIVATE BY DESIGN
• Drinks you log are saved to Apple Health if you choose, and sync with iCloud
• Sleep data is read only when you turn on the sleep report, and never leaves your iPhone
