Faslip is an app that uses measurements from Health Connect to calculate and provide users with fatigue and sleep indicators, ensuring they are aware of their fitness levels before starting work. This helps contracting companies make informed decisions based on their employees' results, preventing accidents during work activities.

Faslip doesn't directly use an external measurement device, but it does require one to function. The information received from the user comes through an external measurement app; that is, the user must wear a measurement device (smartband, smartwatch). This device must sync with its brand's app (Xiaomi, Samsung, Fitbit, or any brand connected to Health Connect). Health Connect then retrieves the synchronized data from the device's brand app, and Faslip processes this information to generate the fatigue and sleep indicators.
