■ 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.

Parallask

Most planners assume you do one thing at a time. Parallask doesn't. Build your day as a timeline. Tasks have real durations, so they can overlap, sit side by side, or leave deliberate gaps. The shape of the plan is the plan. Drag a bar to move it, drag its edge to make it longer, tap a gap to fill it. Then give it a start time and walk away. At the appointed moment the plan begins on its own, counting down on the Lock Screen and in the Dynamic Island, with the app closed. Each task announces itself as it starts. Nothing needs you to be watching. TIMELINE EDITOR Lay out tasks by dragging. Parallel work sits on its own lane instead of being squeezed into a list. Switch to Task List whenever you'd rather read than drag. RUNS ITSELF Schedule a plan for a time and the days it repeats. Reminders arrive ten minutes before it starts, and the countdown reaches your Lock Screen without you opening anything. A SESSION YOU CAN SEE While a plan runs, the whole timeline plays out with a moving playhead: what's on now, what's next, how long is left. A HISTORY THAT STAYS PUT Finished runs are kept exactly as they ran. Rewrite the plan afterwards, or delete it entirely, and the record of that morning is unchanged. LABELS Five colour-coded labels, named by you and shared across plans, so a glance at the week tells you what kind of day it is. YOUR DAY STAYS YOURS No account. No sign-in. No server, no analytics and no tracking of any kind. Everything you create lives on your device and nowhere else. FREE AND MAX Parallask is free: one plan of your own, the five built-in label colours, and starting sessions whenever you like. Parallask Max adds: - Unlimited plans - The full label colour palette - Scheduling plans to start on their own Max is available as a monthly or annual subscription, or as a one-time lifetime purchase.
