Best Calendar and To-Do Apps for Students (2026)

A calendar and a to-do list do different jobs. The calendar shows what happens at a set time: lectures, work shifts, exams and due dates. The to-do list holds the work that has no fixed time, such as reading a chapter or drafting two paragraphs. Students who keep both, and check them daily, rarely miss a deadline.

We compared the most useful apps for this on price, free plans, reminders and platforms. Prices change often, so we show the date we last checked them. Where sources disagreed on a price, we leave it out rather than guess.

How we chose

Each app was judged on:

• Cost for students: a useful free plan or a genuine student deal.
• Reminders and recurring tasks: both matter for weekly readings and assignments.
• Syncing: your calendar and tasks should match on laptop and phone.
• Simplicity: an app you stop using is no help, however powerful it is.
• Platforms: whether it works with the devices students actually own.

These picks are not paid placements, and we earn nothing from any link below.

Quick picks

• Best calendar: Google Calendar.
• Best free to-do app: Microsoft To Do.
• Best for many courses and projects: Todoist.
• Best all-in-one: TickTick.
• Best for Apple-only users: Apple Calendar and Reminders.

A simple two-app setup that works

1. Put fixed things in the calendar. Add your class timetable as repeating events, then every assignment due date and exam as a one-off event with the weight in the title, such as "History essay due (30%)".
2. Put flexible work in the to-do list, broken into steps that take one study session or less. "Write essay" is too big. "Outline sections 1 to 3" is a task.
3. Add start dates for big assignments as calendar events two to three weeks before the due date, so you are reminded to begin, not only to submit.
4. Plan your day each morning. Pick three tasks from your list and give them a time in the calendar.
5. Review weekly. Spend 15 minutes on the same day each week checking the next three weeks and tidying your list.

Our guide to a weekly planning routine walks through that review step by step.

Getting reminders right

Reminders only help if they are few and meaningful:

• Deadlines: set a reminder two or three days before the due date as well as on the day.
• Recurring tasks: weekly readings and quizzes are ideal for repeating tasks.
• Fixed-time events: one reminder, about 15 to 30 minutes before.
• Everything else: no reminder. Your daily list is the reminder.

Constant notifications train you to ignore them, so turn off alerts from apps that are not about deadlines.

Sharing calendars and lists

Sharing is useful in a few situations:

• Group projects: a shared calendar with milestones and meeting times keeps everyone on one schedule.
• Housemates and family: a shared calendar for rent, bills and visits avoids clashes.
• Study partners: a shared list of chapters to cover splits the load and keeps you accountable.

Share only what the other person needs, and keep personal commitments on a private calendar.

Setting up your calendar for the semester

Spend one session in the first week of term building the calendar:

• Create a calendar per type of commitment, such as Classes, Work, Deadlines and Personal, each with its own color. You can then hide a layer when you want a cleaner view.
• Enter every deadline from every syllabus, with the weight in the title and the submission time in the notes.
• Add exam dates and the last day to withdraw from each course, which are easy to miss.
• Set the default event length to 30 minutes so quick entries do not become hour-long blocks by accident.
• Turn on a weekly agenda email or widget so the week ahead is in front of you without opening the app.

Common mistakes

1. Using the calendar as a to-do list, which fills it with vague blocks you ignore.
2. Keeping tasks in several places, so nothing is trustworthy. Choose one list.
3. Adding deadlines only on the due date, with no start date or warning.
4. Over-engineering the system, with more tags and filters than tasks.
5. Never checking it. The best app is the one you open every morning.

Which should you choose?

Try your choice for two weeks of real deadlines before switching. Moving tasks between apps later is easy, and the habit of checking daily matters far more than which app you use.
