About CalorieMeter Pro
CalorieMeter Pro is a free, high-precision tool designed to help you understand your body's energy needs using the most accurate scientific formulas available today.
Our Mission
In a world filled with complex diet fads and paid subscription apps, our mission is simple: democratize health information. We believe that everyone deserves access to accurate, science-based tools to manage their health without barriers. Whether you're an athlete optimizing performance or someone starting a weight loss journey, CalorieMeter Pro provides the fundamental data you need—completely free, forever.
How It Works
Our calculator uses two of the most respected equations in metabolic science:
- Mifflin-St Jeor Equation: Considered the gold standard for accuracy in modern populations. It calculates your Basal Metabolic Rate (BMR) based on your age, gender, weight, and height.
- Harris-Benedict Equation: A classic formula that has been refined over decades, offering an alternative perspective on your metabolic needs.
We then combine your BMR with your specific activity level to determine your Total Daily Energy Expenditure (TDEE). This is the precise number of calories you burn in a day. From there, we apply safe, sustainable adjustments to help you reach your goals—whether that's losing fat, maintaining weight, or building muscle.

CalorieMeter Pro is designed for adults (ages 18+) who want to take a quantitative approach to their nutrition. It is particularly useful for:
- Fitness enthusiasts tracking macros
