One column. Open a thread and the Reader unfolds beside it. Close it, and the window shrinks back.
A key for everything. Gmail's own shortcuts, on Mac and iPad.
Your email,minimal.
Cardinal is Gmail with everything else removed, for iPhone, iPad and Mac. Your mail sits in one quiet column. Open a thread and it appears beside it.
Everything else waits until you ask.
Color only shows up when it means something. The rest is white or true black.
Works offline. Archive, star and reply anywhere. Gmail catches up when you're back.
Undo send. A few seconds to take back what you just sent.
Write for Me. A few words become a draft, written on your device. You press Send.
Sparrow, rebuilt.
Sparrow was a small Gmail client until Google bought it in 2012. Cardinal keeps the idea and rebuilds it for iPhone, iPad and Mac, with Liquid Glass.
Requires iOS, iPadOS or macOS 26.
