Caffeine Tracker: Coffee Log

About this app

Meet your mysterious new companion — a 3D character that lives inside your caffeine tracker and reacts to your body's caffeine level in real time. Sleepy when you're clean, dancing when you're at peak, jittery when you've had too much. The numbers on a graph, finally with a face. MyDailyCaffeine is the smart way to track and manage your daily caffeine intake. Coffee, espresso, tea, matcha, energy drinks — log them all in seconds and see exactly how your body feels, minute by minute. ◆ Meet Your Mystery Mascot (NEW) A 3D animated character appears on your Today tab. Their pose and mood are driven by your actual caffeine curve, so a single glance tells you more than any chart. Tap them for a surprise reaction. Drag to rotate. Pinch to zoom. You can toggle them off anytime from Settings. ◆ Track Caffeine Intake Record every caffeinated drink with one tap. Coffee (95mg), espresso (63mg), green tea (28mg), matcha (70mg), energy drinks (80mg), cola, cocoa, chocolate — and create custom drinks with your own values. ◆ Daily Caffeine Limit Set a personal daily cap (default 400mg, the WHO healthy-adult guideline). See at a glance how much you've consumed versus your target. ◆ Remaining Caffeine in Your Body Know exactly how much caffeine is still active in your system using a 5-hour half-life model. Decide whether that afternoon cup is a good idea — before you pour it. ◆ Calendar Heatmap Spot weekly patterns and habit shifts with a color-coded monthly calendar. ◆ Statistics and Trends 7, 30, and 90-day analytics. Daily averages, most-consumed drinks, long-term trends. ◆ Streaks and Badges A gentle streak system and achievement badges keep the daily logging habit going. ◆ Widget Support Home Screen widgets for an instant caffeine summary, no app open required. ◆ Apple Watch App Log your coffee right from your wrist and check your current caffeine level at a glance. ◆ Personalization Eight theme colors inspired by coffee (espresso, mocha, caramel, matcha, chai, berry, midnight, slate). Dark mode included. ◆ Privacy First All data stays on your device. No account. No cloud. No tracking. ◆ 33 Languages English, Japanese, Korean, Simplified & Traditional Chinese, Spanish, French, German, Portuguese, Arabic, and many more.

Minor improvements and bug fixes.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
