CoffeeCut: Bedtime Estimate

You drank a coffee. You probably know the cup and size, not the caffeine milligrams. CoffeeCut starts there. Choose a familiar coffee, tea, soda, or energy drink, choose its size and number of servings, then save. The app estimates the milligrams underneath. A custom entry remains available when a product label gives a precise value, and a built-in converter turns milligrams per 100 ml into the total for the container. Accuracy can improve without making technical units the price of entry. See a bedtime estimate before the next cup. The Today screen shows what was consumed, what may remain now, and what may remain at the bedtime you set. A next cup budget compares that estimate with your own daily target. These are planning numbers, not measurements from your body. Each result shows the caffeine half-life assumption used by the calculation, and Settings lets you adjust that assumption instead of hiding it behind a confident-looking answer. One calculation drives every summary. Today, History, and Report use the same deterministic caffeine engine, so the same records do not become different totals on different screens. History groups ordinary drink entries by day and keeps familiar drink names visible. Report turns the recent pattern into a compact share card. The Night Roast card theme is an optional cosmetic reward after watching an ad; the normal report and sharing flow remain available without it. The catalogue includes common drink and size presets. Presets are estimates because recipes, brands, brewing time, and serving sizes vary. CoffeeCut labels estimates as estimates. It does not diagnose sensitivity, predict sleep quality, recommend a medically safe dose, or replace professional advice. If you are pregnant, taking medication, managing a health condition, or reacting strongly to caffeine, use guidance from a qualified professional rather than an app estimate. Your drink log stays on this device. There is no account and no cloud database. You can review entries, remove a mistaken record, change bedtime and daily target, and erase all local data from Settings. Core logging and calculations work without a connection; advertising needs a connection. Simple first. More precise when you want it. Languages: English, 한국어, 日本語, 繁體中文, Deutsch, Français, Español
