Exxentric

The kMeter provides real-time feedback for training sessions using the Exxentric kBox, kPulley, LegExx and LegFlexx. The devices are used by athletes and rehab patients for a wide array of flywheel training applications. The Exxentric app connects to the kBox, kPulley, LegExx and LegFlexx and enables you to display and record training data including power, overload, range of motion and force.

The app provides coaching functionality where coaches can keep track and register training for clients.
The app also allows users to view workout content in the form of videos to be used as a guide during training, or simply as inspiration. Some of the workouts can also be followed step by step, which allows for simultaneously connecting to a kMeter and registering data during the workout.
