Sidekeys turns an iPhone into a secondary Mac display that shows app-aware shortcut keys and serves as a control deck for meetings and creative tools. It's interesting as a contextual input surface, but the concept is close to existing iPad sidecar/Stream Deck-style utilities.

Target audience: mac power users, developers, and creative professionals
