Calun is a minimalist, highly customizable calendar app specialized for monthly viewing. With the new Calendar Groups, you can organize overlapping work, personal, and hobby schedules and switch between them with a single tap. It syncs seamlessly with iOS standard calendars (iCloud, Google Calendar, etc.) to support your daily life intuitively. Swipe left/right to move between months, and swipe up/down to jump between "years" instantly—checking last year or next year is faster than ever.
