I was typing "I'm free Tuesday 2-4 and Wednesday morning" into emails multiple times a day. Sometimes I'd get it wrong - a meeting I forgot about, a timezone I miscalculated - and the back-and-forth would start. My calendar already knew the answer. I just needed a way to get it out quickly.
Calendly solves this, but sending someone a scheduling link feels transactional. For the kinds of meetings I take - leadership syncs, cross-team alignment, exec conversations - I'd rather it feel like I wrote it myself. Because I did decide to send it. The app just did the typing.
No links for your counterpart to click. No accounts for them to create. A clean message that lands in their inbox looking like you took 30 seconds to check your calendar and type it out.

Or download the DMG
Download the latest release, open it, and drag Availability Click to your Applications folder. Grant calendar access on first launch.
Requires macOS 14 (Sonoma) or later. The app is signed with a Developer ID and notarized by Apple, so it opens without a security warning.
- Launch Availability Click from Applications
- Grant calendar access when prompted
- Left-click the calendar icon in your menu bar - availability copied to clipboard
- Cmd+V into whatever you're writing.
Right-click the menu bar icon for longer date ranges, your current version, Check for Updates, Settings, and Quit.
The basics
- Left-click copies your availability for the default range
- Right-click gives you Next week, Next fortnight, or Next 30 days
- Option+click opens a preview so you can check the output before copying
- Ctrl+Shift+C copies from anywhere without touching the mouse (configurable, and it needs no Accessibility permission)
- Reads every calendar synced to your Mac - iCloud, Google, Outlook, Exchange
- Pastes rich into Mail, Google Docs, and Notion with bold day labels - plain editors get exactly the plain text
- Times and day labels follow your locale - 24-hour locales get 24-hour output
- Failed clicks tell you why - hover the icon and the tooltip names the reason
- Two Shortcuts and Spotlight actions - "Get Availability" returns the text, "Get Availability Slots" returns structured start/end times for automation - and neither touches your clipboard
Smart about what counts as "busy"
- Declined meetings don't block your time
- Cancelled events are excluded
- Events you've marked as "free" (focus time blocks, etc.) are excluded
- All-day events don't block time slots
- If you click on a Friday evening or weekend, it rolls forward to next week automatically
Configurable
- Working hours with 30-minute granularity (8:30am start, not just 9am)
- Working days - any combination, not just Mon through Fri
- Default range: "This week" or "Next 2-30 business days" with a slider
- Today buffer: minimum lead time before showing a slot (30 minutes to four hours)
- Calendar selection: pick which calendars count as "busy"
- Slot rounding: snap times to clean 5, 10, 15, or 30-minute boundaries
- Minimum slot duration: hide gaps shorter than 15, 30, 45, or 60 minutes
- Output format: plain text or Markdown
- Time zone with GMT offset
Preview popover (Option+click)
- See the formatted text before it hits the clipboard
- Timezone picker with search - convert to your recipient's local time before copying
- Format toggle - switch between plain text and Markdown
- Copy button puts exactly what you see on the clipboard.
The Shortcuts actions are a stable contract. There are two:
- Get Availability returns your free slots as formatted text.
- Get Availability Slots returns them as structured entities - each with a raw
startDate,endDate, anddurationMinutes- so a Shortcut can compose its own output. The result card shows a formatted time range and your time zone; the value fields stay raw dates.
Both take a Range (the same choices as the menu, plus your configured default) and an optional Business days override (2-30; out-of-range values are clamped). Both read your stored settings - buffer, calendar selection, rounding, minimum slot - so a Shortcut sees exactly what a click would. Both require the Mac to be unlocked, and neither writes to the clipboard.
The names are frozen: intent names, parameter names, and entity property names will not be renamed or retyped, because a rename would break every Shortcut built on them. New parameters and new intents are the only way this surface evolves.
No analytics. No tracking. No network connections. No data collection.
The app reads your calendar locally through Apple's EventKit framework. Nothing leaves your Mac. It runs inside the macOS App Sandbox with calendar access as the only entitlement - network permissions aren't even granted. There is physically no way for it to phone home.
One scoping note: the Shortcuts action hands your availability text to your own Shortcut, and what that Shortcut does with it - including sending it somewhere - is up to you. The app itself never calls the network. "Check for Updates" opens the GitHub releases page in your browser for the same reason.
