Coffee Addiction Tracker

Brewlog turns every cup of coffee into a clear picture of your day: what you drank, how much caffeine is still in your system, and which of your own brews is actually worth repeating. Log in three taps • Pick a drink type, size and star rating — that's a logged cup • Quick-log tiles for espresso, latte, filter and cold brew from the Today screen • Edit, re-time or delete any cup at any point Know your caffeine right now • A circular gauge shows your current estimated caffeine against your own daily limit • A curve chart traces caffeine rising and falling across the day using a half-life model • Set your limit, half-life and cut-off time to match how you actually sleep Find the brews worth repeating • Save any cup as a recipe with dose, water, grind and brew time • Recipes rank themselves by real ratings, brew count and recency • A rating histogram and trend sparkline show if a brew is holding up or drifting See your patterns • Week, month and year views of intake, timing and drink mix • A 24-hour histogram shows your peak coffee hour • Streaks, a 12-week contribution grid and personal records An anonymous daily comparison • See where your intake sits against everyone else using Brewlog, with no accounts and no names • A shared Bean of the Day card with a tasting note everyone sees the same day • Everything works fully offline — comparisons and beans just refresh when you're back online A short game for the brew wait • Roasting Rush is a quick tapping game for the minutes a coffee takes to brew • Best score sits alongside your streak and records Brewlog keeps your cups, recipes and notes on your device. Only an anonymous daily digest — cup count, total caffeine and drink mix — ever leaves it, and that can be turned off at any time.
