Daynode is a fast, lightweight, local-first calendar application for Mac that combines calendar events, reminders, and notes in a single focused interface. Designed for users who prioritize privacy and speed, Daynode keeps all working data stored locally on the user's Mac, using Google Calendar access only for selected calendar features. The app supports Google Calendar and Apple Reminders sync, Markdown formatting for notes and events, and offers multiple visual themes ranging from quiet neutrals to richer colors. A built-in command-line interface enables quick access and task automation for power users. Available as a one-time $20 purchase during early development.
