CaffTrace: Caffeine Tracker
Coffee Intake & Sleep Cutoff
Free · Designed for iPad. Not verified for macOS.
Coffee now, caffeine at bedtime? Preview your next cup, check estimated remaining caffeine, and log familiar drinks from Today.
Coffee now. How much caffeine at bedtime?
CaffTrace is a caffeine tracker and calculator for coffee, tea, and energy drinks. Log what you drink, follow an estimated caffeine curve, and plan your next cup around bedtime.
SEE YOUR BEDTIME ESTIMATE
View estimated caffeine remaining at your next bedtime alongside the current amount. Set your bedtime directly from Today. Estimates use your logged drinks and chosen half-life.
PREVIEW YOUR NEXT CUP
Before saving a drink, see its estimated contribution to your total caffeine at bedtime. Choose a preset or enter milligrams from the product label. Editing an entry replaces that drink in the preview rather than counting it twice.
LOG FAMILIAR DRINKS FASTER
Today offers shortcuts to recently used drink presets. Check the amount and time before saving. Coffee, tea, cola, energy drinks, and dark chocolate presets are included; actual products vary.
FOLLOW YOUR DAILY TRACE
See a half-life-based curve, including caffeine carried over from earlier drinks. Plan an estimated cutoff using your bedtime, preferred remaining-caffeine threshold, and reference drink.
REVIEW AND CORRECT YOUR HISTORY
Browse entries by date, edit or remove a drink, and clear your history from Settings.
ENGLISH AND KOREAN
New installs follow the device language when supported. Switch between English and Korean from Settings.
ON-DEVICE RECORDS
Your caffeine log and calculation settings stay on your device. No CaffTrace account is required. The free app uses Unity LevelPlay with Unity Ads. Personalized-advertising consent is declined and a sale/sharing opt-out signal is sent; advertising providers may still process data described in the privacy policy.
CaffTrace uses a simple exponential half-life model. Displayed values are estimates, not measurements, diagnoses, treatment advice, or medical safety limits. The app does not track actual sleep or blood caffeine concentration. Metabolism varies by person.
