On mobile
KeyCastr is a command-line tool, so there is no phone app for it — a phone has no shell to run it in. You'll need a desktop, or a remote shell into a machine that has one.
KeyCastr is developed by its own authors. This page is an independent reference; we are not affiliated with or sponsored by the project. The command shown here was reproduced from the project's public documentation — always check the project's own documentation before running anything.
