Built with Swift and SwiftUI. No Electron, no web views, no bloat.
Note
This repository is the Meridian community hub — translations, issue tracking, and releases. Meridian is a closed-source macOS app; the source code is not published here. Download Meridian from Releases (free) — a one-time license key from Gumroad unlocks it on up to 3 Macs.
Download Meridian from Releases. Unzip, move Meridian.app to Applications, and launch. To unlock it, buy a one-time license key ($12) from Gumroad — you'll get it by email — then enter it and click Activate.
Your license works on up to 3 Macs at a time. You can deactivate devices from Settings.
The app includes a built-in update checker -- open About and click Check for Updates to see if a newer version is available.
- Team Roster -- Add your team members with their time zones. See availability status at a glance: working, late hours, off, or sleeping.
- Day Arc Visualization -- Semicircular sun position shows where each person is in their day. Toggle between filled and outline styles.
- Overlap Band -- Stacked working hours at the bottom of the team view. Highlighted overlap shows when everyone (or most) are available.
- Time Slider -- Preview future hours with a drag slider. 30-minute snaps, shows how availability changes throughout the day.
- Meeting Planner -- Select participants, set duration, and filter by availability preference (all working, at least N, any overlap). Auto-ranked best slots with star indicator.
- Calendar Integration -- Optional Calendar.app integration shows busy times with hatching overlay in the planner. Requires calendar permission.

Download the latest .zip from Releases, extract it, and move Meridian.app to your Applications folder.
Buy a license key ($12 one-time) from Gumroad, then launch Meridian, enter the key from your purchase email, and click Activate.
Click the + button to add team members. Set their name, time zone, and working hours.
On first launch you may see a prompt saying "Meridian wants to use your confidential information stored in your keychain." This is expected -- Meridian stores an encryption key in your login keychain to protect your team data (names, time zones, working hours) with AES-256 encryption. It also stores your license key in the keychain. Click Always Allow so you won't be asked again.
If you enable the Calendar integration in the Meeting Planner, macOS will ask "Meridian would like to access data from other apps." This is required to read your Calendar.app events and show busy times in the planner. Click Allow to enable it. Calendar access is optional -- the app works fully without it.
