Time Blocking: How to Plan Your Day + Best Time Blocking Apps

If your to-do list keeps growing while your day disappears, time blocking is worth a try. Time blocking means giving every part of your day a job: you schedule blocks of time on your calendar for specific tasks or types of work. The best time blocking app depends on how you plan: an automatic scheduler if your day changes a lot, a plain calendar if you prefer control and a visual planner if you think in pictures.

Below: a 5-step method, an example of a time-blocked day, the difference between time blocking and time boxing, and the best time blocking apps by type, free options included.

What is time blocking?

Today the method is best known through Cal Newport, the author of Deep Work, who has promoted it for years and published The Time-Block Planner (2020).

Why it helps:

• Fewer decisions. You decide once, the evening before, instead of asking "what now?" ten times a day.
• One kind of work at a time. In a 2009 paper, Sophie Leroy showed that part of your attention can stay on the task you just left, especially when it isn't finished. She called this attention residue. A block keeps you on one thing.
• A reality check. You see in the morning, not at 6 PM, whether your tasks fit in your day.

Does it work? No large trial has tested time blocking on its own. The closest evidence is a 2021 meta-analysis of 158 samples with more than 53,000 people, in which Brad Aeon, Aïda Faber and Alexandra Panaccio found that time management was moderately related to job performance, academic achievement and wellbeing. Most of the studies were correlational, so that's a link, not proof, and the link was stronger for wellbeing than for job performance.

It isn't for every day. If your work is mostly interruptions (a support queue, a toddler at home), block less and leave more buffer.

Two variants you'll see: task batching groups similar small tasks, like all your calls, into one block. Day theming gives each weekday one focus, like Mondays for meetings and Fridays for admin.

How to time block your day in 5 steps

To time block your day, list what has to happen, place your fixed anchor blocks first, put deep work where your energy peaks, batch the small stuff and leave buffer. Our suggestion: do your time block scheduling the evening before. Once you're used to it, it takes 10 to 15 minutes.

1. List what has to happen

   Write down everything tomorrow has to hold, work and life. Tasks and meetings, but also the gym and dinner. If the list is long, sort it first: our Eisenhower Matrix asks two questions per task (is it urgent, is it important?) and splits your list into do now, schedule, delegate or shrink, and delete.

2. Set your anchor blocks first

   Put the parts of your day that don't move on the calendar before anything else. That's your morning routine, your evening routine and fixed appointments. Anchors give the day a set start and end, so the middle can bend. A morning routine is easiest to keep when you stack its habits in a fixed order, and if you want a longer one, here's how to wake up earlier.

3. Block deep work when your energy is highest

   Give your hardest task your best hours, in one block of 90 to 120 minutes. For many people that's the morning, but not for everyone. Our chronotype quiz asks five questions and suggests your best focus window. If you keep putting that task off anyway, see how to stop procrastinating.

4. Batch small tasks into one or two admin blocks

   Email, messages, forms and quick calls go together. Two admin blocks of 30 to 45 minutes, one late morning and one mid-afternoon, are a good start. Outside those blocks, the inbox stays closed.

5. Add buffer and review every evening

   Leave empty time, and spend 15 minutes at the end of the day planning the next one. Blocking time for nothing feels wasteful, but things will run long; that's normal, not failure. In the review, move what didn't happen and block tomorrow.

How long should a time block be?

Between 30 and 120 minutes works for most blocks (our rule of thumb). Go short, 30 to 45 minutes, for admin, calls and errands. Go long, 90 to 120 minutes, for deep work like writing, coding or studying. Past two hours, add a break.

Each block works like an if-then plan: "At 9:00 AM, at my desk, I write the report." In a 2006 meta-analysis of 94 independent tests, Peter Gollwitzer and Paschal Sheeran found that plans that set when and where had a medium to large effect on reaching goals. Our Atomic Habits cheat sheet covers the same trick, which researchers call implementation intentions.

Example: a time-blocked day (template)

Here's a sample time-blocked day for a knowledge worker with office hours. It starts and ends with a routine block and leaves buffer twice. Each row is one time block: a start, an end and one job.

Notice what isn't blocked: the evening between 4:45 and 9:30 PM. You don't have to schedule dinner with your family to make the method work.

A student version: classes are your fixed blocks, so place one or two 90-minute study blocks around them, with a morning and an evening routine as anchors. A parent version: school drop-off and pickup are anchors too. Put deep work in the hours the kids are out, and keep one buffer block for the call from the school nurse.

To use this as a template, copy the Time and Block columns into your calendar as events, delete what you don't need and set the two anchor blocks to repeat every day. For another sample day built around one protected focus block, see the schedule in our monk mode guide.

Time blocking vs time boxing: what's the difference?

A time box is a fixed time limit for one specific task. Time blocking decides when you work; time boxing decides how long a task may take. "Write the proposal from 9:00 to 11:00" is a time block. "The proposal gets 90 minutes, then it goes out" is a time box.

They work best together: block the day first, then box the tasks inside each block. A two-hour deep work block might hold a 60-minute box for the proposal and a 45-minute box for the slides.

Boxing pushes back on an old line that still rings true. In a 1955 essay in The Economist, C. Northcote Parkinson wrote that work expands to fill the time available. It was satire about bureaucracy, not a study, but a hard stop does keep "polish the slides" from eating an afternoon.

The Pomodoro Technique, created by Francesco Cirillo, is time boxing in short rounds: focus until the timer rings, take a short break, and take a longer break after four rounds. Our Pomodoro timer runs the classic 25/5 rhythm, has a 50/10 preset for longer focus blocks and switches between focus and breaks for you.

The best time blocking apps, by type

The best time blocking app is the one that matches how your days run: an automatic scheduler if your plans change every hour, a plain calendar if you like control, a tasks-plus-calendar app if your to-do list runs your day, and a visual planner if you think in pictures. Below are nine time blocking apps (also called block scheduling apps), grouped by type, with no forced number one.

Found your type? Here's how the nine apps compare.

What do time blocking apps cost? Plain calendars cost nothing, several planners have free plans with paid upgrades, and Motion, Sunsama and Akiflow are paid subscriptions. Prices change often, so check each app's own site before you subscribe.

Automatic schedulers: for days that keep changing

An automatic scheduler takes your tasks, deadlines and meetings and builds the time blocks for you. When something runs over, it moves the rest.

• Motion. An AI calendar that plans your tasks by priority and deadline and replans when your day shifts. Best for: people juggling many projects and due dates. Strong point: you stop dragging blocks around. Weak point: there's no free plan, and handing your day to an algorithm doesn't suit everyone.
• Reclaim. Works on top of the calendar you already use and defends recurring blocks, like focus time, lunch or a workout, moving them when a meeting lands. Best for: people who run their day from Google Calendar or Outlook and want to protect their deep work. Strong point: a free Lite plan, with paid upgrades. Weak point: no planner of its own; it works inside your calendar.
• FlowSavvy. Schedules your tasks into open slots and reschedules what you miss. Best for: automatic planning with a free plan to start. Strong point: a free plan with the core features. Weak point: like every auto-scheduler, it's only as good as your estimates, so a "30-minute" task that takes two hours pushes every block after it.

Our pick: Reclaim if you live in Google Calendar or Outlook and want to start without paying; Motion if you want the app to plan everything and don't mind a subscription.

Tasks plus calendar: when your to-do list runs your day

These apps start from your task list and help you drag tasks onto the calendar as blocks.

• Sunsama. Walks you through a daily planning routine: pick today's tasks, estimate them, drag them onto your calendar, then look back at the end of the day. Best for: people who want a calm, guided plan each morning. Strong point: it builds the daily review in. Weak point: no free plan, only a 14-day trial, then a paid subscription.
• Akiflow. Collects tasks from email, chat and other tools in one inbox, and you drag them onto your calendar as time blocks. Best for: people whose tasks arrive from everywhere. Strong point: one place for everything, with fast keyboard shortcuts. Weak point: paid only, and it's built for power users.
• TickTick. A to-do list with a calendar view, a habit tracker and a built-in Pomodoro timer. Best for: one app for tasks, calendar and focus. Strong point: a free plan, with a paid Premium plan if you want more. Weak point: blocking is manual, so it won't reschedule your day for you.

Our pick: TickTick for most people, because it puts tasks, calendar and a focus timer in one app with a free plan; Sunsama if you'd pay for a guided daily plan.

Plain calendars: can you use Google Calendar for time blocking?

Yes. Google Calendar is the simplest time blocking app there is: it costs nothing, runs on web, iOS and Android, and is probably on your phone already. Make each block an event, give each type its own color (blue for deep work, gray for admin, green for routines) and set your anchor blocks to repeat daily.

Apple Calendar works the same way and comes built into iPhone, iPad and Mac. The weak point of both: nothing moves on its own. When a meeting runs over, you drag the rest of your day yourself.

Our pick: Google Calendar. Time block in it for two weeks before you pay for anything.

Visual planners: if you think in pictures

• Tiimo. Shows your day as a visual timeline with icons, colors and countdowns, so you can see time passing. Best for: people who lose track of time or think visually. Strong point: it makes time visible, and there's a free version. Weak point: it's built for planning a day, less for big work projects with many tasks.
• TimeBloc. A visual daily planner for iPhone where you place blocks on a simple timeline. Best for: a clean, phone-first view of one day. Strong point: very little to learn, and it's free to download. Weak point: fewer tools for complex work, and extras sit behind a paid Premium upgrade.

Our pick: Tiimo, for a timeline that shows time running out instead of just listing tasks.

Why time blocking fails (and how to make it stick)

Here are four common reasons a time-blocked day falls apart, each with a simple fix.

• No buffer. We're bad at estimating: in a 1994 study by Roger Buehler, Dale Griffin and Michael Ross, 37 psychology students predicted when they'd finish their theses, and on average they took longer than even their own worst-case guess. Fix: plan 15 minutes of buffer for every 2 hours of work, and block only about three quarters of your day (our rule of thumb).
• Blocks that are too small and too precise. A day of 15-minute blocks is a to-do list with extra steps. Fix: keep blocks at 30 minutes or more, and give small tasks a shared admin block.
• Giving up when the plan breaks. A broken plan by 11 AM is normal. Fix: take two minutes to re-block the rest of the day.
• No fixed start or end. Without anchors, the morning starts in your inbox. Fix: the same morning and evening routine block, at the same time every day.

Greatr, the app we make, isn't a calendar or a time blocking app, and it doesn't replace one. It covers the two anchor blocks: you build a morning routine and an evening routine from small habits in a fixed order, like water, stretching and journaling in the morning and "plan tomorrow" at night, then tap Play and run them one habit at a time.

The app lock keeps the apps you choose, like Instagram or TikTok, locked until your routine is done, so your morning block doesn't start in a feed. Its Focus timer can time a deep work block; your calendar handles everything in between.

Does time blocking work with ADHD?

It can, but little research has tested time blocking for ADHD specifically, and experiences differ. If a strict schedule doesn't hold, try looser blocks: three or four a day instead of ten, a visible timer for each one, and a 15-minute restart block after lunch for whatever slipped. A visual planner that shows time passing helps some people more than a calendar grid.

If ADHD makes planning hard, a doctor or an ADHD coach can help you find what fits.

How to make time blocking a daily habit

Keep your anchor blocks at the same time every day and let the rest move. That repetition is how habits form: in Phillippa Lally's 2010 study of 96 volunteers, a new daily behavior took a median of 66 days to feel automatic, with a range of 18 to 254 days, and missing one day did not materially affect the process.

Make the daily review a habit: a fixed block at the end of your workday, as in the sample day, or a step in your evening routine. Looking back counts: in a 2016 meta-analysis of 138 studies, Benjamin Harkin and colleagues found that monitoring progress helped people reach their goals, more so when the progress was recorded. For what to put in those routines, browse our good habits examples.

Starting time blocking as a January goal? Read why most New Year's resolutions fail first, then start small: two anchor blocks and one deep work block.

Your next step: tonight, take 15 minutes and block tomorrow with just three blocks (your morning routine, one 90-minute deep work block and your evening routine). Tomorrow night, check which of the three happened, then block the next day the same way.
