Doze: Caffeine Tracker

What will still be in your blood at bedtime? Doze is a gentle caffeine tracker for people who love their coffee and love their sleep too. Log a drink, see how much caffeine is still in you, and find out when it is time to put the cup down. • Quick logging: choose from a built-in list of coffee, espresso, tea, matcha, energy drinks, soda and pre-workout, or type in a custom amount • A live estimate of the milligrams in your body right now, plus today's curve hour by hour • A "last coffee by" time, worked out from your bedtime and the amount of caffeine you can sleep through • A daily limit line, set by default to 400 mg, the amount the FDA mentions as generally not associated with negative effects for healthy adults (general information only) • History and streaks, so you can see your days at a glance and string together easy nights • No account and no sign-up: your log stays on your device • Light and dark themes for morning cups and late-night checks Free and Pro. Doze is free to use and shows ads. Doze Pro gives you unlimited history and stats, saved custom drinks, a reminder before your cutoff, CSV export and personal half-life fine-tuning, and it removes the ads. Pro is optional and comes as a weekly or yearly subscription (the yearly plan starts with a 3-day free trial) or as a one-time lifetime purchase. Doze collects anonymous usage statistics and crash reports to help us improve the app. Doze gives estimates for information only and is not medical advice. If you are pregnant, take medication or are sensitive to caffeine, please ask your doctor. Privacy Policy: https://doze-socrepho.web.app/privacy.html
