Not all calories are the same. Stop guessing and calculate your exact fat burn in grams.
Not all calories are created equal. Stop guessing and start quantifying your fat loss.
Ever wondered how much of your workout was actually burning fat? Most fitness trackers give you a single "Calories" number, but your body doesn't work that way. Depending on your heart rate, age, and biometrics, your body chooses between burning glycogen (carbs) and fat.
FatBurnd is the first app designed to reveal the true metabolic efficiency of your workout. Using advanced physiological heart rate heart rate logic, it calculates how many grams of pure fat you oxidized during your session.
