Horizontal

Horizontal is a work in progress. It is not finished software and should not be used for production work. Keep backups of anything you open with it.

Horizontal is a PCB design tool for macOS and iPadOS. It opens .hprj and .horizontal projects and shows the schematic and the board.

Released versions are read-only and will not write project files. The drawing tools change what is on screen, but nothing is saved back to disk.

Board

View board and schematic simultaneously. Highlight nets to aid debugging

Schematic

Blocks and sheets are listed in the sidebar. Nets, buses, junctions, net ties, and labels each have their own layer that can be turned off.
