Calorie trackers like MyFitnessPal record what you ate. Fuelin tells you what, when and how much to eat. It sets daily calorie, carb, protein and fat targets from your planned and completed workouts, gives you fueling guidance for training and race day, and adjusts your upcoming meals to what you've already eaten. If you already log food in MyFitnessPal, it syncs to Fuelin through Apple Health.

Fuelin starts with your goal, body weight, gender, athlete experience level and daily activity level. It then adds your planned and completed workouts, your resting metabolic rate (RMR) and performance markers such as functional threshold power (FTP) and threshold pace. Fuelin estimates your RMR, FTP and threshold pace, or you can enter your own values if you have them. Its recommendations are built by sports dietitians and based on the latest sports science.
