Free daily planner and circular timetable compared — 24Houring vs Structured, Tiimo, Google Calendar and Korean planner apps

By 24Houring · 2026-10-22

Short answer: 24Houring is a free daily planner that divides your 24 hours into one clock-like circle. It opens in the browser with no sign-up, and editing the circle, templates, the table view, record mode and image or PDF export are all free, with no ads. It suits students, people preparing for exams, shift workers and anyone building a routine who wants to see how sleep, work, study and rest share the day. If you want per-task reminders and repeats, or need to line up time with other people, another tool may serve you better.

What to look for in a daily planner

• How it shows the day: a circle or a top-to-bottom timeline. A circle makes proportions and empty time easy to read; a vertical timeline is better for order and exact times.
• Free limits and ads: which of repeats, reminders, widgets and the web version are free, and whether the free tier shows ads.
• Account and devices: whether you need an account, and whether it runs on iPhone, Android and a computer.
• Plan and reality: whether you can only plan, or also record the day you actually had and compare.
• Keeping it: printing, saving as an image, and putting it on your phone's home screen.

At a glance

Details for the other services come from their official help and product pages and app store listings as of October 2026. Prices vary by region and over time.

A short, fair note on each

• Structured: puts tasks and events on a single timeline that runs down the screen. Its help center says almost every feature is free and the app shows no ads. Recurring tasks, calendar import and AI are Pro, and Android and the web still lack some features. It suits people who work through the day in order.
• Tiimo: a visual planner designed with neurodivergent people in mind, combining to-dos, a focus timer, widgets and AI planning. Device support is broad, including Apple Watch and Mac. The free version runs only in the phone apps; the web planner needs a trial or a subscription.
• Google Calendar time blocking: no new app, just blocks such as "study 9–11" placed as events in the calendar you already use. It is the strongest option for inviting people and finding a shared time. Focus time, which declines meetings while you concentrate, is limited to certain Workspace accounts.
• Plem: an iPhone app inspired by the circular timetables Korean children draw for school holidays. You decorate it with stickers, see plans and to-dos in widgets, and earn small rewards for goals. A good pick for iPhone users who enjoy a cute, decorated planner.
• Haru Plan: an Android app that gathers a daily plan, a school timetable, automatic NEIS timetables and school meals, and a diary, which makes it practical for school students. It shows ads, and its last update on Google Play was in January 2025.

Where 24Houring is strong

• The whole day sits on one circle: midnight at the top, 6 AM on the right, noon at the bottom. The size of sleep, work and empty time shows before you read a single label. The 12-hour day (06–18) and night (18–06) views edit the same day.
• Tap the ring to split a block, drag a boundary to set the time, and give each block a name, colour and icon. When labels crowd, check the table view.
• Record mode logs the day you actually had so you can lay it over the plan. Checking blocks off gives a daily completion rate, and a short diary sits on the same screen.
• Start from ten templates (office worker, college student, exam prep, night shift, miracle morning, toddler routine and more), and make a different plan for each weekday. The free plan keeps up to three saved timetables.
• Save as PNG or PDF to print or share. The Android app's home-screen widget shows the circle with a live clock hand.
• No sign-up, and after the first load it keeps working offline. There are no ads on the free plan or on Pro.
• If you asked an AI chatbot to draft your day, there is a published link format that opens that plan pre-filled in 24Houring, so you do not retype it. It asks before loading anything.
• The calendar, D-day counter and mandal-art chart live in the same app, so a goal can be carried down to a date and then to a day.

Where it is honestly weaker

• It is not a task manager. It is built for dividing the day into broad blocks. For subtasks, deadlines and recurring to-dos, Structured or a to-do app is more comfortable.
• Reminders assume the app is open. Block-start alarms are free, but push alarms that arrive with the app closed are Pro.
• No iPhone app or widget. On an iPhone you use the browser or the web app added to the home screen; the home-screen widget is Android only.
• It is not a shared planner. For finding time with other people, Google Calendar or 24Houring's shared calendar works better.
• Short blocks look small on a circle. On a day full of ten-minute items, the table view is easier to read.
• On-device storage has limits. Clearing site data can lose your plans; without sync, download the JSON backup now and then.

How to start in 24Houring

1. Press Open 24Houring. The circle opens straight away, with no sign-up screen.
2. Pick a template or start from an empty circle. Place the hours that are hard to move first, such as sleep, school or work.
3. Tap the ring to split blocks, drag the edges to fit, and choose names, colours and icons. Adding travel, meals and breaks as blocks brings the plan closer to the real day.
4. Check blocks off as the day goes, and in the evening use record mode to log what actually happened and compare.
5. Save it as a PNG or PDF from Export to print or share.

FAQ

Is there a free circular timetable app?

Yes. 24Houring lets you build a circular daily planner in the browser with no sign-up and save it as an image or PDF, all free and without ads. There is an Android app; on an iPhone you open it in the browser or add it to the home screen.

Can I use 24Houring instead of Structured or Tiimo?

If the goal is to see how the day is allocated and compare the plan with what happened, it may be enough. If you want reminders and repeats on every task, or an AI-drafted day, Structured or Tiimo fits better. You can also keep the broad allocation on the circle and the detailed tasks in a to-do app.

Why not just time-block in Google Calendar?

If you need to line up time with other people, Google Calendar is the better tool. A calendar's vertical grid shows order and exact times; a circle shows the proportions of the whole day and its gaps. Keeping appointments in the calendar and today's broad allocation on the circle works fine.

Can I print my daily schedule?

Yes. Export saves a PNG image or a PDF for printing. On the free plan it carries a small 24houring.com mark; Pro saves without it.
