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. NEVER MISS A THING Set reminders on any note and get a push notification when it matters ā on Mac or iPhone. ONO PRO Unlock reminders, note organization, and extended history with a Pro subscription.

Verdict
The clearest difference is in-app purchases: Ono at none against Calendar Pro's 2. Calendar Pro's advantage is update cadence (weekly vs fortnightly). On price, ads, device support and iOS requirement there is nothing between them.
