This tool lets you add the coffee, energy drinks, and tea you've had today and automatically totals up your caffeine intake. Choose your user type — adult, pregnant, or youth (weight-based) — to instantly see what percentage of the recommended daily limit you've reached. Everything is calculated right in your browser, so nothing you enter is sent to a server.
How to use
- Select your user classification (adult, pregnant, or youth) at the top; if youth, enter your weight.
- Tap preset drink buttons like Americano, Espresso, or Cold Brew to add each drink you've had today.
- Adjust the count for each drink or remove an item with the [x] button.
- Check the total caffeine amount and progress bar at the top to see your intake as a percentage of the limit.
FAQ
- How is the caffeine limit calculated?
- Adults use a 400mg limit, pregnant users use 300mg, and youth limits are calculated as body weight (kg) times 2.5mg.
- Can I add a drink that's not in the preset list?
- Currently you can only choose from six presets: Americano, Espresso, Cold Brew, Canned Coffee, Energy Drink, and Green/Black Tea.
- Is my drink data saved anywhere?
- No, all calculations happen only in your browser session — refreshing the page resets the list and nothing is stored on a server.
