Gerberoid

Gerberoid is an Android viewer for Gerber files, the file format commonly used to describe printed circuit board artwork for fabrication. It lets a user open Gerber data on a mobile device and inspect board layers away from a desktop CAD environment. This can be useful when checking exported manufacturing files, reviewing layout artwork, or referring to PCB layer information while discussing a board design.

The application is published by Marcus Comstedt and distributed under the GPL-3.0-or-later license. Its role is viewing rather than full PCB design or editing, so it should be understood as a file inspection tool. Since it runs on Android, its practical use depends on mobile screen size, file access on the device, and the Gerber files the user provides.
