Itsycal: what the free tier covers

Most people who look up Itsycal's price are really asking a different question. Is there a catch? Will a useful feature turn out to sit behind a subscription six weeks from now? Is the free version a trial for something else?

The short answer is that Itsycal has no paid tier, no in-app purchase, no license key and no account. The "free tier" is the entire app. The more useful answer is about what that free app is designed to do, where its scope ends, and what a person juggling Google, Exchange and iCloud calendars ends up paying for anyway, in money or in time, around it.

Everything below was checked against the developer's website, the version history, the update feed and the public source repository on September 15, 2026.

The price, and the four things worth checking besides it

Itsycal costs nothing. It is downloaded as a zip file from the developer's site, Mowglii, and it is also available as a Homebrew cask, which at the time of writing installs the same 0.15.12 build. There is no sign up step and nothing to activate.

A price of zero says little on its own. A free app can be discontinued, sold, or converted to a subscription, and for software that sits in the menu bar all day those events matter more than the number. So four things were checked, not one.

Check Status on September 15, 2026 Where it was checked
Discontinued No announcement. Version 0.15.12 was published on April 5, 2026 Version history and the Sparkle update feed
Downloads or new users halted No. The download link is live and there is no registration Official site
Change of developer or owner No announcement. Still published by Mowglii About page and GitHub
Price change No announcement of paid plans. Only a donation page About page and donation page

The repository also shows a 0.15.13 tag dated September 13, 2026. The project has existed on GitHub since January 2016 and is released under the MIT License.

What "free" includes: the whole feature list

Because nothing is gated, the useful exercise is to list what the app does. The items below come from the official feature page, the help page and the version history.

Viewing

  • A month grid that opens from the menu bar, with the option to show up to two months at a time.
  • An agenda under the grid covering no events, one to seven days, 14 days, or 31 days.
  • ISO 8601 week numbers.
  • A customizable menu bar display that can replace the system clock with any date and time pattern.
  • Light, dark or system theme, and three text sizes.

Creating and joining

  • A new event form with title, location or video call, URL, all day, start, end, repeat, alert, notes and calendar.
  • Repeat options of none, every day, every week, every two weeks, every month and every year.
  • Deleting events on calendars that allow it.
  • Detection of meeting links from Zoom, Microsoft Teams, Google Meet, Webex and other services, with a join button that turns on fifteen minutes before the start. Command and J opens the first active meeting in the agenda.

Navigating

  • Keyboard control with arrow keys or Vim style H, J, K and L, including repeat counts, so typing 21 and then L moves forward 21 days.
  • Shift, Command and T to jump to any date.
  • A URL scheme, itsycal://date/ followed by a date, to open Itsycal on a given day from scripts or launchers.
  • An optional hourly beep, which can be replaced with a custom mp3 file.

There are also hidden preferences, set from Terminal with the defaults command and documented in the version history, such as showing event details on hover. They are free as well.

Donations: what they are and what they are not

The developer's site has a donation page listing Ko-fi, PayPal and Cash App. No amount is suggested, and nothing changes in the app after a donation. There are no ads to remove and no features to unlock, so a donor and a non-donor run identical software.

That has two practical consequences.

First, for a company, there is no purchase to process. No invoice, no receipt for a license, no seat count. If an IT policy requires a record for installed software, Itsycal falls under whatever process applies to free, open source tools rather than purchased ones.

Second, the MIT License means the code can be read and built. The repository's contributing notes explain that Xcode can sign a local build without an Apple Developer account. For an app that has full access to every calendar on the Mac, being able to inspect what it does is arguably worth more than the zero price. The repository describes the scope in one line:

If you want, it will display your calendar events as a companion to the Mac Calendar app. You can also create and delete (but not edit) events. Source: github.com

What no amount of money adds

With paid apps, a missing feature often means a higher plan. With Itsycal, the boundaries are design decisions, and paying would not move them.

No editing. Events can be created and deleted, not changed. Double clicking an event opens it in Apple's Calendar app, where time, attendees and notes are edited. On a day when meetings keep shifting, every change is a trip to another app and back.

No accounts of its own. Itsycal cannot sign in to Google or Microsoft. It shows only calendars already added to macOS through Internet Accounts or the Calendar app. The help page notes that some shared Google calendars appear only after they are selected in Google Calendar's sync settings, and that delegate calendars from other providers cannot be shown directly.

Mac only. The official site distributes a Mac app and nothing else. On a phone or a Windows PC, the calendar provider's own apps fill that role.

Gregorian calendar only. The help page says dates will be wrong if another calendar system is selected in macOS.

No travel time, scheduling links or natural language entry. None of these appear in the feature page, help page or version history. Planning around a commute still happens elsewhere.

Costs that sit outside the app

Itsycal being free does not make the calendar setup free. The calendars it reads live in services with their own terms. A personal Google account, a Google Workspace plan through an employer, a Microsoft 365 subscription, or iCloud: all of those continue exactly as before. Itsycal does not replace any of them and does not reduce what they cost.

Hardware is a second consideration. The current build requires macOS 11 Big Sur or later. The version history page still offers free older builds: 0.14.1 for macOS 10.14, 0.11.17 for 10.12, 0.10.16 for 10.10 and 0.8.15 for 10.8. Those builds do not receive current fixes, so on an older Mac the trade is a free app that stays as it is.

The largest cost is usually time, and it is easy to miss because it never shows up on a bill. Looking at the schedule from the menu bar takes seconds. Changing it means switching to Calendar, finding the event, editing, and switching back. For someone whose day is mostly fixed, that is trivial. For someone whose meetings move several times a day across two or three accounts, that loop is the real price of the setup.

What a free, individually maintained app asks of its users

Paid software often comes with a support channel and some expectation of response. Itsycal comes with neither promise, and the developer is clear about how help works.

Updates. Itsycal uses the Sparkle framework to announce new versions, and automatic checking can be turned off in the General tab. If it is off, fixes are missed. The version history shows why that matters: 0.15.7 introduced excessive CPU use, fixed in 0.15.8, and 0.15.9 fixed a memory leak on macOS 26 Tahoe.

macOS upgrades. After the upgrade to macOS Ventura, some users with non iCloud accounts saw crashes. The developer published a workaround in November 2022: remove and re-add those accounts in Internet Accounts. For a Mac used for work every day, reading the version history before a major macOS upgrade is a sensible habit.

Support. The About page gives an email address and asks people to read the help page first, since it usually answers faster. Bug reports should include the Itsycal version, macOS version, Mac model and year, and whether the Mac is Intel or Apple silicon. The GitHub repository listed 89 open issues and pull requests combined on September 15, 2026. There is no service level, which is reasonable for a free tool, and worth knowing if the schedule is business critical.

Deciding whether free is enough

The money question closes at zero. The decision that remains is where rearranging the schedule should happen. Three questions settle most cases:

  • How many times a day does an event need to change? A handful fits comfortably with Itsycal plus Calendar.
  • Is maintaining accounts in System Settings, including Google sync settings for shared calendars, acceptable work?
  • Is a Mac only view enough, with phone checks handled by other apps?

If all three answers are comfortable, Itsycal and Apple's Calendar cost nothing and cover the job. If one of them is not, the comparison is between the time currently spent and the price of a full calendar app.

A one week test that costs nothing

Because there is no trial clock and nothing to cancel, the cheapest way to answer the question is to run the setup for a normal working week and keep a simple tally.

Day one: make every calendar visible. Add each account in System Settings under Internet Accounts, open Calendar to confirm the events arrived, then tick every calendar in Itsycal's General tab. Set the agenda to seven days so the whole week is in view. Assign a keyboard shortcut in the same tab so opening the dropdown does not require the mouse.

Days two to five: count two things. The first is how many times Itsycal answered a question on its own, such as "when is the next meeting" or "is Thursday afternoon free". The second is how many times it sent the work to Calendar because an event needed to move, gain an attendee, or change its repeat rule. A note on paper or a tally in a text file is enough.

End of the week: compare the two numbers. If glances far outnumber hand offs, the free setup is doing its job and there is nothing to buy. If hand offs are frequent, or if events were missed because a shared calendar never appeared, the gap is in editing and account handling, which is exactly the part no donation or upgrade to Itsycal can change.

The test also surfaces problems that have nothing to do with price. A calendar that does not show up points to the Google sync settings or to the Calendars permission. Week numbers that disagree with a colleague's point to the ISO 8601 setting. Fixing those first keeps the decision about paid software honest, because it separates configuration issues from genuine limits of scope.

What to change first

Start by counting how often events are edited in a typical day, because that is the one cost Itsycal cannot remove. If the number is high, Compared with other calendars lists Mac calendar apps by what they cost over three years, with Itsycal shown at zero, and Buy shows how Caltimate splits what stays free from what needs a license.

Frequently asked questions

Is Itsycal really free, or is there a paid version?

It is free, with no paid version, no in-app purchase and no account. As of September 15, 2026, neither the developer's site nor the repository announces paid plans. A donation page exists, but donating does not unlock anything.

How can someone donate to Itsycal's developer?

The Mowglii donation page lists Ko-fi, PayPal and Cash App. No amount is suggested. Because a donation does not buy a license, it does not produce the kind of invoice a company purchasing process usually expects.

Does Itsycal work on older versions of macOS?

The current build needs macOS 11 or later. Older builds remain available for free on the version history page, including 0.14.1 for macOS 10.14 and 0.11.17 for macOS 10.12. Those older builds do not receive new fixes.

Can Itsycal be used at work without buying anything?

Yes, there is nothing to buy. It reads whatever calendars the Mac already has, including Exchange or Google Workspace accounts added in Internet Accounts. Any company rules about installing free, open source software still apply.
