Minimalist calendar-based notes and journaling app. Guiding principles: # Simplicity You pick a day on the calendar and add a note to that day. Basic usage is as simple as that. No clutter, no distractions, no ads. # Reliability Your notes are stored as plain markdown files in iCloud or on your own device. Edit them with your preferred apps, copy or sync them wherever you want, and keep access and control regardless of Gregor itself. # Polish Access information easily, edit markdown from a native UI, and use local AI features to easily search and summarize your notes.
