The interface provides a number of customizable touch controls to send and receive messages:

Faders / Rotary controls / Encoder controls / Push buttons / Toggle buttons / XY pads / Multi-faders / Multi-push / Multi-toggles / Multi-xy pads / LEDs / Labels / Time & battery displays

Additionally the program can send Accelerometer data. The application comes with example layouts and completely custom layouts can be constructed using the free TouchOSC Editor application.

Still one of the best custom control apps


TouchOSC has been around a while, and a lot of competing apps have come along since. Yet we still use TouchOSC for straight forward and flawless app control throughout our studio. It's got a very quick learning curve, and does pretty much everything you need for streamlined studio and live control.

Couldn't live without it.

Hey guys, I know this is a long shot and probably a lot of work, but is there any way you guys can create an Apple Watch version of this app? It would not need all the benefits that you get with the iPad or iPhone, but it'd give you the opportunity to have a couple of Buttons and maybe a slider or knob right there in your wrist ready to go! You guys and your app rocks!

Can’t beat it!


This app is amazing. You should definitely have a little networking knowledge and controller mapping basic knowledge to use. But still easy enough for beginners imo. I’m a dj and use it as a basic light controller. You can design your own templates with OSC Editor. Very cool. Saved me a lot of money in the long run. This app can be used for sooooo many things.
