In 2012, we set out to create a powerful, customizable DRO that small shops and home machinists could actually use and afford. TouchDRO started as a way to get more done with our own hobby-grade manual machines. Today, it is trusted by tens of thousands of machinists around the world. With feedback from hobby machinists and commercial customers, we keep improving and refining the system, with a steady focus on flexibility and ease of use.

TouchDRO runs on readily available Android tablets. It works with a wide range of modern and legacy DRO scales and encoders, including many glass, magnetic, and capacitive scales that traditional DRO boxes can't use.

TouchDRO lets you build and configure a powerful, full-featured digital readout around your machines and the way you like to work. As your needs change, you can adjust the system with them, so your DRO helps you work faster, make fewer mistakes, and keeps up as your projects and skills grow instead of holding you back.
