Adaptive TDEE Calculator is a free lifestyle application available on Android platforms. The app calculates the amount of calories that the body burns each day based on the user's caloric intake and body weight. This feature makes it incredibly easy to know how much to eat, preventing weight loss or gain plateaus, and bulking too quickly.

The app is different from other TDEE calculators because it is adaptive. It calculates the TDEE based on the actual body weight changes and caloric intake of the user, instead of providing a rough approximation based on estimated activity levels. The app uses linear regression to determine the rate at which the user is gaining or losing weight and estimates the TDEE based on that information.

The app also allows syncing with any food tracker that supports exporting its weight and calorie information to Google Fit. It is important to note that MyFitnessPal only exports weight data, and Cronometer no longer exports weight or calorie data. The app's privacy policy states that weight and calorie data imported from Google Fit are only stored locally on the user's phone and are not shared with anyone.
