TouchDRO is a free Android app developed by Yuriys Toys that serves as a front-end for a do-it-yourself DRO project. It uses an Arduino or MSP430-based wireless controller to read a wide variety of scales. The app is designed to offer all the functionality found in a commercial DRO unit while taking advantage of Android's touch interface. With TouchDRO, users can enjoy a powerful and flexible digital readout system that can be used with the vast majority of modern DRO scales.

The latest version of TouchDRO includes a readout for up to three linear axes, an angular axis, and a tachometer. Additionally, it offers a configurable user interface with mill and lathe modes, support for up to six machines, virtually unlimited point memory organized into workspaces, machine-specific tool banks, and a graphical workspace preview. TouchDRO can be used with the vast majority of modern DRO scales and offers the functionality of a high-end DRO unit with the convenience of the multi-touch Android display.
