Bluetooth stroke rate tracker
Swimtraxx has developed a swim tracking device that helps you keep track of the frequency of each of your strokes in real time. Stroke by stroke. Swimtraxx One works with Bluetooth connection. After measuring your stroke rate during a swim workout the data gets sent to the Swimtraxx app where you can keep track of all your swimming information.
Because Swimtraxx One measures stroke rate next to many other swim specific parameters, it’s the smartest swim specific system ever.
