CapsulePad

CapsulePad is a native Mac and iPhone/iPad app for quick notes that stay out of your way until you need them. On the Mac, CapsulePad docks a thin pill of colored notes to the edge of your screen. Move your pointer close and it fans out into labeled tabs — click one to open it full-size, or drive the whole thing from the keyboard (⌥⌘N for a new note, ⌥⌘A to see every note, ⌥⌘L to archive the one in front). Reorder notes by dragging, color-code them for quick scanning, and archive or permanently delete the ones you're done with. Your notes sync automatically across every Mac and iPhone/iPad signed into the same iCloud account, so a note you jot down at your desk is already there when you pick up your phone. For anything you'd rather keep private, lock individual notes with Face ID, Touch ID, or your device passcode. A locked note's title stays visible so you can still find it, but its contents stay encrypted until you unlock it — and it asks again every time you open it. Back up everything at once as Markdown, plain text, or a full-fidelity CapsulePad archive you can import back in later, on this Mac or another. CapsulePad has no account system, no ads, and no analytics — your notes stay on your own devices and sync only through your own iCloud, the same as any other Apple app.
