Proton Control play online

Use the app to program and control the Proton smart tennis practice machine from Hydrogen Sports (you must own a Proton to use the app). With the app you can easily run the built-in practice routines, or create your own with just a few taps. Select a target, spin and speed and the Proton takes care of the rest. The app also allows updating the firmware of your Proton when new versions are available.
