Fat-burning zone is calculated based on Age, Gender and Weight. It, however, will take a time to reflect a calculated fat-burning zone. When weight or age is changed, the change is not reflected immediately, and the data that has been revised on a smartphone is saved on the device only when updating the data. After this, the fat-burning zone will be updated when the data measured on the device is uploaded to the server.
