Best Task and Calendar Apps in 2026: 6 Options Compared

A task list tells you what needs doing. A calendar tells you when your time is already committed. The best task and calendar apps bring those two views together so you can decide what will realistically fit.

However, these apps do not all solve the problem in the same way. Some begin with detailed task management and add a calendar layout. Others turn the day into a visual timeline, guide you through a planning routine, or automatically adjust your schedule.

This guide compares Flick, Todoist, Things 3, TickTick, Structured, and Sunsama by their current official features. There is no universal winner: the best choice depends on how you plan, which devices you use, and whether you need personal organization or shared work.

The quick answer

• Choose Flick if you use Apple devices and want personal tasks, projects, calendar events, and time blocking in one straightforward planner.

• Choose Todoist if you want deep task management, shared projects, and broad platform support.

• Choose Things 3 if you want a polished, list-first personal task manager for Apple devices and only need calendar events as context.

• Choose TickTick if you want tasks, calendar views, habits, a Pomodoro timer, and other productivity tools in one app.

• Choose Structured if you think visually and want tasks, routines, and events arranged along a daily timeline.

• Choose Sunsama if you want a guided professional planning routine that pulls work from other task and project tools.

What should a task and calendar app do?

A calendar integration can mean several different things.

An app may simply display events above a task list. Another may let you give tasks a start time and duration. A more calendar-focused planner may let you drag unscheduled work into open periods, resize it, and move it when the day changes.

Before choosing an app, consider:

• whether tasks and events are visible in the same daily view;

• whether you can turn a task into a time block;

• whether planned time is separate from a deadline;

• how quickly you can reschedule unfinished work;

• whether projects, priorities, reminders, and recurring tasks are supported;

• which desktop and mobile platforms are available;

• whether you need shared projects or external work-tool integrations;

• whether you want to plan manually or use automatic scheduling;

• and whether the free or paid model matches how you intend to use the app.

If you are new to this workflow, start with the practical guide to organizing tasks and calendar together.

Features and plans can change. Check each product’s current official pages before choosing based on a specific paid feature.

Flick: best for straightforward Apple task and calendar planning

Flick is built around one central workflow: capture tasks, organize them, and place important work beside the events already using your time.

Tasks and calendar events appear together in a daily planning view. You can drag a task onto the calendar, resize its time block, and move it when the day changes. Planned working time remains distinct from deadlines and reminders, which is useful when a task must be completed by Friday but you intend to work on it on Tuesday.

Beyond daily scheduling, Flick supports an inbox, areas, projects, project sections, priorities, notes, attachments, deadlines, reminders, and recurring tasks. Its current App Store listing supports iPhone, iPad, Mac, and Apple Watch, with Apple and Google Calendar events available in the planning workflow.

Flick is a strong fit when you:

• plan primarily for yourself;

• use Apple devices;

• want more structure than a basic to-do list;

• prefer to decide your schedule rather than let an algorithm arrange it;

• and want time blocking without building a complex planning system.

It is not the right choice if Android or Windows support is essential. Flick also does not currently present itself as an automatic AI scheduler.

Todoist: best for cross-platform task management and collaboration

Todoist is a task manager first. It provides projects, priorities, labels, filters, recurring dates, reminders, comments, assignments, and shared workspaces across platforms.

Todoist’s current time-blocking documentation shows day and week calendar layouts where tasks with a date, time, and duration appear beside connected calendar events. Unscheduled or all-day tasks can be dragged into time slots, and their duration can be adjusted.

The calendar layout and task-duration features are included in Todoist’s paid plans, while the free Beginner plan retains core task management and calendar integration with lower limits.

Todoist is a strong choice when:

• you move between different operating systems;

• task capture and project organization are more important than a visual daily planner;

• you need to assign or discuss work with other people;

• or you want filters and custom views across many projects.

Compared with Flick, Todoist offers greater cross-platform and collaborative depth. Flick provides a more directly Apple-focused personal planning experience where the calendar is central from the beginning.

Things 3: best for a polished, list-first Apple workflow

Things 3 is a personal task manager for Mac, iPhone, iPad, Apple Watch, and Apple Vision Pro. Its design emphasizes clean task lists, projects, areas, headings, tags, start dates, deadlines, and a focused Today view.

Things can display Apple Calendar events in its Today and Upcoming lists. This gives you useful schedule context while reviewing your tasks.

However, Things does not natively send its to-dos to Apple Calendar. Its support documentation recommends an Apple Shortcut when users want to create calendar blocks from tasks. That makes Things better suited to list-first planning than direct calendar time blocking.

Choose Things when:

• you use Apple devices exclusively;

• a refined personal task-management experience is the priority;

• you like separating Today, Upcoming, Someday, areas, and projects;

• and viewing calendar events beside a list is sufficient.

Choose Flick instead when you want to drag tasks into an actual daily calendar, resize their planned duration, and continuously adjust the schedule.

TickTick: best for combining many productivity tools

TickTick combines task management with calendar views, habit tracking, a Pomodoro timer, reminders, priorities, filters, and other planning tools.

Its free plan includes task management, reminders, cross-platform sync, and a basic calendar view. TickTick Premium adds multiple calendar views, task duration, larger limits, more filters, and additional customization.

TickTick is useful if you want a single product to cover several methods:

• manage projects and recurring tasks;

• schedule work in calendar views;

• build and track habits;

• run focused Pomodoro sessions;

• and review productivity statistics.

That breadth is its advantage. It can also be unnecessary if your main requirement is simply seeing tasks and calendar events together and creating realistic time blocks.

Flick is more narrowly centered on Apple task-and-calendar planning. TickTick is the broader toolbox and supports more platforms.

Structured: best for visual timelines and routines

Structured presents the day as a continuous visual timeline. Tasks, routines, and events occupy specific periods, making it easy to understand the order and shape of the day.

It also provides an inbox for work that does not have a time yet, plus daily, weekly, and monthly views. Structured Pro adds calendar import, recurring tasks, custom notifications, AI planning, and other features, although feature availability differs between iOS, Android, and the web app.

Structured is a good fit when:

• you prefer a chronological timeline over a traditional task list;

• routines and repeated daily activities matter;

• visual structure makes a busy day easier to understand;

• or you want an approachable planner with optional AI assistance.

Its official support documentation says direct collaboration between Structured users is not currently available. It is primarily a personal planner rather than a shared project workspace.

Compared with Flick, Structured emphasizes the visual sequence of one day. Flick adds more explicit areas, projects, sections, priorities, deadlines, and task organization around that calendar workflow.

Sunsama: best for guided professional daily planning

Sunsama is designed around a deliberate daily planning process.

It can import tasks from tools including Asana, ClickUp, GitHub, Jira, Linear, Notion, Todoist, and Trello. During daily planning, you review meetings, select tasks, estimate their duration, check the predicted workload, defer what does not fit, and establish a shutdown time.

Tasks can be timeboxed by dragging them onto Google, Outlook, Apple, or Sunsama’s internal calendar. Sunsama also offers automatic scheduling and rescheduling options.

Sunsama is a strong fit when:

• your tasks already live across several work platforms;

• you want a guided start-of-day planning routine;

• calendar-based workload projections are valuable;

• and you are comfortable paying for a professional daily planning service.

Its current pricing provides a 14-day trial followed by a subscription, with no free-forever plan. That makes it a more substantial commitment than a lightweight personal planner.

Flick is simpler and Apple-focused. Sunsama is better suited to professionals who want to consolidate several existing work systems into a guided daily planning layer.

How to choose the right app

Choose based on your devices

If you need Android, Windows, or Linux support, look first at Todoist, TickTick, Structured, or Sunsama and verify the features available on each platform.

If your workflow is already centered on iPhone, iPad, Mac, and Apple Watch, Flick and Things provide more Apple-specific experiences.

Decide whether you are task-first or calendar-first

Choose Todoist or Things when projects and task lists are the main system and calendar visibility is supporting context.

Choose Flick, Structured, or Sunsama when the timeline of the day is central to how you decide what to do.

TickTick sits between those categories by offering both detailed task features and calendar tools.

Decide how much automation you want

Flick and Things leave planning decisions primarily to you.

Structured offers optional AI planning, while Sunsama includes guided planning and automatic scheduling tools. Todoist and TickTick provide increasingly capable assistance and integrations without making automatic scheduling the entire product.

Manual planning offers control. Automation can reduce repetitive scheduling work. The right choice depends on whether you want software to propose the plan or simply make your decisions easier to execute.

Separate personal planning from team coordination

Flick, Things, and Structured are most clearly oriented toward personal planning.

Todoist provides shared projects, assignments, comments, and team workspaces. Sunsama connects heavily with professional work systems, while TickTick supports shared lists and collaboration within its wider personal productivity feature set.

If several people need to own, discuss, and report on work, evaluate collaboration before visual design.

Test the workflow with a real week

Do not choose from a feature checklist alone.

Add your actual meetings, classes, appointments, deadlines, and recurring responsibilities. Capture the tasks competing for the remaining time. Then try to plan the week without overloading it.

Pay attention to:

• how quickly you can capture a task;

• whether today’s capacity is obvious;

• how much effort it takes to schedule and reschedule work;

• whether unfinished tasks remain trustworthy;

• and whether you still want to open the app after the initial setup.

Which task and calendar app is best?

There is no single best task and calendar app for every workflow.

Todoist is stronger for cross-platform task management and collaboration. Things offers an exceptionally focused Apple task manager. TickTick combines many productivity methods. Structured makes the day visually approachable. Sunsama provides a guided layer across professional tools.

Flick is designed for people in the Apple ecosystem who want the task list and calendar to function as one realistic personal plan. It provides enough project structure to organize meaningful work while keeping the central action simple: decide what matters, then give it a believable place in the day.

Try task and calendar planning with Flick

With Flick, you can capture tasks in one inbox, organize them into areas, projects, and sections, add priorities or deadlines, and view them beside your Apple and Google Calendar events.

When a task deserves protected time, drag it onto the calendar. Resize the block to match the work and move it when plans change. Flick does not automatically decide what matters most; it gives you the context to make that decision yourself.

If that matches how you want to plan, download Flick for free and test it with one real day. Add the commitments that cannot move, choose the work that matters, and schedule only what genuinely fits.
