To be able to calculate your personal mental energy use and recovery, you need to wear the Fitbit tracker which measures your heart rate in a continuous way. The Mindstretch app only uses the heart rate data collected by Fitbit. No additional data is stored in the Mindstretch app. (*) Mindstretch measures the energy used for mental tasks. Note that the mental load experienced by your body (= physiological stress) is not necessarily identical to the perceived one. As every individual reacts to mental load in a different way, the measures will vary for each person. Why do you need a Fitbit tracker that measures heart rate? The Mindstretch app calculates your individual mental energy use and recovery levels based on different variables (i.e. heart rate) measured on the body. How to use this Mindstretch app? 1. Wear consistently the Fitbit tracker and sync it to the Fitbit app 2. Select the Mindstretch app and create a new user account or login with your credentials. 3. Select as device the Fitbit tracker and allow permission to share the data of your Fitbit account with Mindstretch 4. You are set!
