About

The 7 Brew Caffeine Calculator is a browser extension compatible with Chrome, Edge, and Firefox. After clicking the icon, you select a beverage, choose its size, and add any extra shots. It then immediately displays the precise caffeine content in milligrams, the calorie count, your percentage of the FDA daily recommended limit, and an energy level badge categorized as Low, Moderate, High, or Extreme.
