DailyCup: Caffeine Tracker

DailyCup logs the coffee you actually drink in about three seconds, then does the rest. Pick a drink and it fills in the caffeine, calories, sugar and what it cost. One button repeats your last order. Size, milk and sweetness adjust in place, and the numbers follow along. THE CURVE IS THE POINT Caffeine leaves your body on a half-life, not a schedule — roughly 5.7 hours for most adults, closer to 7 if you are sensitive. Half of a 3 pm coffee is still with you around 9 pm. DailyCup plots that decay on the home screen, so you can see what is left rather than guess. It also works backwards from your bedtime and tells you the latest time you could have another cup and still be under the threshold when you go to bed — and says so plainly when the answer is "not today". IT KNOWS YOUR CAFÉ 1,900+ drinks from 50 brands across 28 countries and regions, using each brand's published nutrition data where it exists. Every entry is marked official or estimated, so you know which you are looking at. Can't find yours? Add it — leave a field blank and it is estimated from comparable drinks. REPORTS AND CARDS, ALL FREE Weekly, monthly and yearly reports. Every December, a swipeable recap of the year: how many cups, your biggest day, the drink you kept going back to, and which kind of coffee person that makes you. Turn any week into a card in four styles and send it to whoever will find it funny. All four templates, no watermark, nothing locked. NOTHING LEAVES YOUR PHONE No account. No server of ours. No analytics, no advertising SDK, no tracking of any kind. Everything you log stays in your device's own storage, and the app works fully offline. The only network request it makes is checking for an updated drink library. Export everything to CSV or JSON whenever you want it somewhere else. 21 languages. Free, with no subscription and no in-app purchases. Caffeine, calorie and sugar figures are estimates for reference. They are not medical advice.
