“It was just a busy year again” is not enough to explain how your days actually went. The most honest story of this year is already written in the small records you stacked on your calendar — meetings, tasks, deadlines, and the spaces in between.

Rewind gathers all the events and tasks you logged throughout 2025 and shows you where your time went and how much of it landed there. It turns the year into clear graphs and numbers so you can see:

• When you were at your busiest

• How your weekdays and weekends flowed differently

• How often you switched contexts

• Who you spent the most time working with

You don’t have to set anything up. Rewind simply uses the data that’s already there.

We also show a Rewind Type based on when you tend to be busiest across the day. If you’d like to see each type in more detail and how it works, you can read more here: https://www.archcalendar.com/2025-rewind

We’re introducing Arch Calendar as a desktop app(Mac).

Arch Calendar started as a quiet workspace in your browser. But sometimes tabs pile up, windows multiply, and Arch often gets buried somewhere in the middle.

The desktop app gives Arch its own place on your computer: a dedicated space for planning your day, separate from the chaos of the browser.

Stay on track with notifications

The desktop app comes with a notification experience tuned for your daily schedule:

• Task reminders that appear shortly before a block starts or ends.

• Event reminders for meetings, with a quick way to jump to the meeting link when available.

• Complete from notification – mark a task as done directly from the toast, without switching back to Arch.

• Snooze options so you can push a reminder a few minutes later when you’re not quite ready.

You can fine-tune all of this in Settings → Notifications — choose when to be reminded, and whether you want sound or a quieter setup.

A quick glance at your day from the menu bar

The desktop Menu Bar (or system tray) gives you a lightweight view of “now” without opening the full app:

• See your current task or event and how much time is left.

• If nothing is running, see when your next block begins or confirm that you have no more scheduled blocks for today.

It’s a narrow strip of information, designed to keep you aware of your day without demanding your attention.

How to install the Desktop App

You can install the Desktop App in two ways:

• From Settings → Download apps inside Arch Calendar, where desktop and mobile downloads live together.

• Directly from our /download page

We’re launching our first mobile apps for iOS.

From the beginning, Arch Calendar has been about one simple idea:

capture what’s on your mind, and plan when to do it.

That’s why the product has always been just two things — Inbox and Calendar.

Bringing This to Mobile

Until now, Arch Calendar lived mainly on the web. But capturing thoughts and tasks isn’t something that only happens when you’re at your desk. It happens when you’re on the move, scrolling through articles, or opening links you want to revisit later.

With Arch Calendar for iOS, you can now:

• Capture tasks instantly into your Inbox.

• Plan your day directly from your phone.

• Send links straight into Arch using the system Share menu. No copy & paste. No extra steps.

  

A Lighter Way to Stay Organized

We didn’t build a different product for mobile. We built the same one, shaped to fit in your pocket. The same Inbox. The same Calendar. Just closer to where your ideas and links appear.

This is only the beginning of the mobile experience.

We’ll keep refining, simplifying, and shaping Arch Calendar so that organizing your day feels as natural as possible — wherever you are, on iOS.

With this update, you can connect multiple Google Calendars simultaneously. Be they work, personal or for different projects. This lets you manage all your commitments in one place without missing anything.

We’ve added new sorting options to the Inbox.

The default sort is still Manual. Your custom order stays the same on every device. We also added Oldest, Title, Priority, and Space so you can organize the Inbox the way you like.

Today Inbox uses one sorting setting, but it applies separately to the Overdue and Today groups. Both groups default to Earliest (ascending start time), so items with earlier start times appear first.

Other Improvements

• Before, you had to turn on Overdue with a filter, and it always showed at the bottom - making unfinished tasks hard to spot. Now, if there’s at least one Overdue task, the Overdue section appears at the top so you can re-plan and avoid missing work.

• You can now find three onboarding helpers at the bottom of Settings.

  • Start Tutorial - Replay Arch Calendar’s core feature walkthrough.

  • Reserve 1:1 Onboarding - Book a 30-minute session with the Arch Calendar team for hands-on guidance.

  • Help Center - Jump to guides on how to use Arch Calendar.

On December 28, 2023, we privately launched our first product. Now, 605 days later on August 25, 2025, we're launching Arch Calendar for everyone.

Our first idea seemed obvious: build an Integrated Inbox that pulls together tasks from Slack, Jira, Gmail, and other tools. We thought bringing everything into one place would solve the chaos of scattered work.

Over 605 days of talking with users, we discovered something different from what we initially thought. The real problem wasn't having tasks spread across different tools. It was the mental mess this created such as constantly switching between apps, losing track of priorities, and feeling overwhelmed by information scattered everywhere.

Building a Focused Product

This changed everything about how we build products. Instead of adding features during our private beta, we started removing them. We cut the Slack, Gmail, and Jira integrations. We removed the Wiki feature. We stripped away anything that wasn't essential.

What remained? Just two things: an Inbox for capturing tasks and a Calendar for planning when to do them. That's it. No complex workflows, no elaborate tagging systems, no endless customization options.

The Essence of Productivity Found in Architecture

We renamed the product because architectural arches perfectly represent our philosophy. Ancient Romans discovered that a curved structure could support massive weight using minimal materials - not by adding more stone, but by placing each piece exactly where it needed to be.

That's exactly what we want for productivity tools. Maximum impact with minimum complexity.

From Digital Fragmentation to Unified Experience

Right now, your schedule lives in one app, your tasks in another, and your notes somewhere else entirely. You're constantly jumping between tools, losing context, and wasting mental energy just trying to stay organized.

Arch Calendar takes the best parts of each - scheduling from calendar apps, task management from to-do lists, and quick note-taking - and puts them in one clean interface. Instead of managing multiple apps, you manage your actual work.

No flashy features. No overwhelming options. Just what you need to get things done.

There was the inconvenience of having to click every time to add tasks in Inbox. To improve this, we've added a shortcut that lets you quickly add tasks by simply pressing 'c' on the main screen. Now quickly add all tasks you suddenly need to jot down to your Inbox.

Other Improvements

• Fixed speed issues in Inbox that occurred when multiple tasks accumulated. Overdue Tasks can now be checked in Today.

• Made toast messages more compact so notifications don't interfere with the calendar, allowing you to focus more on task management.

• Improved speed by over 90% when creating and modifying spaces and tasks in Sidebar and Inbox.
