SnappyNotes

SnappyNotes is a quick-access notes app for Mac users who want to capture thoughts without leaving their current task. Open a note from the edge of the screen or with a shortcut, then keep writing in a floating window or a distraction-free focus mode.

It supports Markdown, checklists, code blocks, images, equations, and diagrams, with PDF export that preserves formatting. Notes sync through iCloud between Mac, iPhone, and iPad, and local copies remain available offline.
