About Calendoc: Parallel Calendars
■ Don't merge. Line them up. Work, side gigs, family, fandom. The more calendars you keep, the harder they are to read when everything is mixed into one timeline. You end up chasing colors and working out which event belongs to which role. Switching calendars hides conflicts on the side you cannot see. Calendoc gives each role its own vertical column. The free version lets you compare up to four columns on one screen, keeping work and personal schedules separate while making double-bookings easy to spot. ■ Built for • Using both work and personal calendars • Moving between several schedules for side gigs or multiple jobs • Freelancing with a separate calendar for each client • Keeping concerts, events, and livestreams in a dedicated fan calendar • Wanting work and private life unmixed, but visible at the same time ■ Included for free UP TO FOUR PARALLEL COLUMNS • Show calendars registered on your iPhone, including iCloud, Google, and Exchange, as side-by-side columns • Day and week views with visibility controls for each group • Arrange column order and choose which calendars appear in each group CORE CALENDAR TOOLS • Create, edit, and delete events, including recurring events • Drag to move events or change their duration • Copy and paste, plus Undo • Search across multiple calendars PLAN YOUR DAY • Place Reminders on your timeline as time blocks • See travel time • Home Screen widgets • Dark mode and multiple languages Core calendar features and up to four parallel columns stay free.
