How to track daily coffee intake

Guide · ~6 min read

Morning espresso, afternoon filter, evening “just one latte”… cups add up quietly. Twilight Coffee Tracker makes your cup goal and estimated caffeine visible. No account; logs stay in the browser.

Caffeine context

A commonly cited upper limit for healthy adults is about 400 mg caffeine per day (varies by person—ask a clinician if unsure). In-app mg values are rough estimates:

• Espresso ≈ 65 mg
• Americano ≈ 95 mg
• Latte / Flat ≈ 75 mg
• Filter ≈ 120 mg

How to use it

1. Open Coffee Tracker
2. Tap the drink type you had
3. Use custom cups for multiples
4. Set your daily cup goal (default 3)
5. Undo or Reset day when needed

Smart habits

• Try cutting caffeine after mid-afternoon for better sleep
• Log “social coffees”—they’re the ones people forget
• Pair with Water Tracker: +200 ml water after each coffee
