The RSP ENCODER (Rotary Encoder) and our app are the digital extension of our inertial machines. The RSP APP is used to measure exercise power in real time via a data connection (Bluetooth technology). Power is measured in watts and in cycles. With these two indicators, the app is able to provide the user with information about the use of the machine and its performance. Users can save their workouts in the chronicle and access them at any time. The app includes presets for each of the 3 machines, including the connected hardware terminal. Our encoder also allows full compatibility with SmartCoach sports software and can monitor the data thanks to the app on the smartphone, tablet or PC with SmartCoach.
