Chunk: This menu-bar time-blocker gets out of your way
Time blocking has been around long enough that the method itself needs no selling. The problem has always been tooling: most apps that support it are either full calendar replacements that demand you reorganize how you work, or stripped-down timers that ignore your existing schedule entirely.
Chunk, however, takes a different approach by filling the gap left by these two categories.
We have been testing Chunk on our M2 MacBook Air running the latest version of macOS. We manage several dozen events every week across multiple calendars and reminder apps. So, we thought of testing whether Chunk could serve as the additional planning layer we need.
What Chunk is
Chunk claims to be a zero-bloat time-blocking utility for macOS. This native macOS app is designed to help you plan your time with an intuitive interface so that you can focus on the action, not the planning process.
The name Chunk alludes to splitting your entire day into manageable chunks that you can easily manage with time-blocking utilities. This app tries to integrate a couple of other utilities, such as a to-do task manager and integration options.
The app also respects your privacy, as your data never leaves your device.
Slide-down panel
The first innovative thing you notice about Chunk is the interface design. Instead of creating a fully-fledged app that takes over your screen, Chunk slides down a panel. You can open it using the global hotkey or by clicking the icon in your menu bar.
In practice, you don’t trade your screen real estate for a time-blocking app. The panel slides over your existing windows rather than displacing them, and you can dismiss it with a single click or hotkey. It’s a small design decision that makes Chunk feel like a utility rather than a commitment.
You can also customize the viewing options to your liking. For instance, if you want to focus on a calendar-based view, you can go for that. There are also options for accessing the templates and other features of the time-blocking utility.
Using this interface to navigate your day, week, or month is easy. To create an event, you can simply drag and extend the time, and you can also use this option to resize the duration of an event. It also keeps a timer on the left that shows when the next activity or event begins.
The one minor friction: there’s no keyboard-only way to create a block — you have to drag. For mouse-first users, that’s fine; for keyboard-heavy workflows, it’s a small but real limitation.
Two-way calendar sync
Chunk also gets right something that most calendar apps struggle with: two-way sync.
This app doesn’t offer synchronization options for its own data, which stays on your device, and this is one of the major privacy claims it makes. However, you can easily connect your calendars and reminder apps with the app to bring your entire schedule to your interface.
At the time of writing, Chunk lets you connect Google Calendar, Apple Calendar, and Outlook Calendar, and it pulls in reminder information from Apple Reminders.
In practice, calendar syncing felt reliable enough that we stopped thinking about it after the first day. That is, we could easily add an event to our Google Calendar, and it would appear on Chunk within, say, five seconds.
Yet, we think you would need some more time to understand how the event-task separation works. You may have to use the option to convert an event to a calendar entry. We had a situation where we kept adding events to the time-blocker, but they didn’t appear in Google Calendar because we were adding everything directly in Chunk.
Tasks and templates
You can use Chunk to keep track of tasks and routines, and everything happens in the same panel. You’d have the option to choose between multiple views, including Day, Week, Tasks, and Templates.
The Tasks section covers the basics well — subtasks, reminders, color codes — and if your task management needs are light, it’s enough to retire a separate app. But it’s not trying to be Things or OmniFocus. There’s no priority sorting, no tagging, and no way to view tasks across projects. Treat it as a capable companion to Chunk’s calendar layer, not a standalone replacement.
Templates are another way to set up routines to integrate into the calendar. If there is a task that you constantly create, or a type of task that you want to set up multiple times, you can create a template. You can then easily drag and drop these templates into your day to set up the task.
Claude desktop integration
The Claude Desktop integration is the most unexpected part of the app — and, for the right user, the most practical. Here’s how it works:
For this option to work, you should have Claude Desktop installed on your Mac. When you go to Claude Desktop and ask it to show your schedule for the next day, it will show you the information retrieved from Chunk. This is also great when you want to add new entries, manage your list, or apply templates without leaving the Claude window. Because Claude is pretty good at managing natural language, you end up saving a lot of time as well.
Chunk claims that your data doesn’t leave your device when you use this MCP integration. For instance, when we want to add a lunch block for the entire week, it makes sense to ask Claude to add it rather than manually block it every day. A simple prompt like “Block 12-1 on all weekdays for lunch” replaces the rather hectic task of adding blocks manually.
We should mention that you don’t need Claude Code or Cowork to do this. A free plan works.
Chunk pricing
In a world where every single product has moved to a subscription model, Chunk seems a little different.
You can test Chunk using the free trial for seven days. It gives you access to all the current features, but you cannot continue using it after the trial. Essentially, there is no free version.
When it comes to Premium Options, you can choose between a Lifetime License and a Family Package.
- The Lifetime License, which costs $19.99, gives you full-time access for 2 Macs and includes all current features and future updates.
- The Family Package gives you access to 5 Macs, includes future updates, and costs $44.99.
You own the software rather than renting it, which aligns well with the local-first philosophy.
What’s missing (or coming)
We don’t want to paint it as a perfect tool. A few things Chunk doesn’t do:
- Currently, Chunk is available only for macOS, and you don’t even get companion apps for Android or iOS.
- The local-first philosophy prioritizes privacy, but it also means there is no cross-device sync. Every time you need Chunk, you must set it up from scratch.
- And the integrations are also currently limited to Google Calendar, Apple Calendar, and Outlook.
For instance, tools like Sunsama offer advanced integrations, but the problem is that you must pay a hefty monthly subscription fee. Similarly, apps like Structured offer similar features on iOS, but you don’t get two-way calendar syncing.
Worth it if you already live in your calendar?
The app does what it says. Blocks go on the timeline in seconds, the calendar syncs without manual refreshing, and the menu-bar panel genuinely stays out of the way until you need it.
The fit is narrow by design. If your work happens on one Mac and you already use Google or Outlook Calendar, Chunk slots in without friction. The $19.99 one-time price means the trial is low-stakes.
Two limitations are worth naming before you commit. There’s no iOS app yet, so if you plan on using a phone at any point in the day, Chunk won’t be there. And the analytics show what you scheduled — not what you completed — so anyone who tracks follow-through as part of their system will need something else for that.
For the right setup, the trial is worth an afternoon. You can download it from https://www.chunkapp.net/
