Ono is a minimal note-capture app for Mac and iPhone. The thought you don't write down is the thought you lose. Ono puts capture one keystroke away — press Ctrl+Shift+O on your Mac and your note is ready before the idea fades. No dock icon. No full-screen takeover. Just a clean, focused popover from your menubar, always within reach. CAPTURE INSTANTLY A global shortcut opens Ono from anywhere on your Mac. Type your thought. Press Cmd+Return. Done. On iPhone, it's always one tap away. BUILT FOR FOCUS Monospaced type, dark background, no distractions. Ono looks and feels like a tool, not a toy. YOUR NOTES, EVERYWHERE Everything syncs between your Mac and iPhone automatically. Capture on the go, review at your desk.
