Appkeys is a macOS menubar app that allows you to easily assign global hotkeys to your most-used apps. That's it!
Appkeys is a vibe-coded simplified remake of one of my favorite apps, Apptivate. I used Apptivate all day every day for many years, long after it stopped receiving updates. Eventually it would crash every time I changed my hotkeys, so I gave up and made my own version. And here it is!
It does one thing and does it well.
