Start up the app and place the Tuna Knobs on the dials. To secure the Tuna Knobs on the screen, push down on the top of the axis until the suction cup is fully attached to the screen. Make sure both the screen and the suction cup are clean.

Now you are ready to start twisting away. Tuna Knobs are essentially styluses and the black rubber is responsible for the conductivity. For the best results, make sure you always turn a knob by touching the black rubber and with slight downwards pressure. This ensures the touchscreen picks up the Tuna Knob signal.

This takes some practice, but don’t worry, you’ll get the hang of it soon enough.

 

 

 

 

So you just got your Tuna Knobs and you’re not quite sure how to get started? Tuna Knobs work on a touchscreen, so you’ll need one of those. iOS, Android or Windows does not matter.Next up you need an app. Though there's a list of compatible apps, you can use Tuna Knobs with any control that is meant to receive a rotary signal and has a diameter larger than the base of the knob. See the Apps page for a list of compatible apps and make sure you have one of these installed on your device.
