Windows Desktop App is here

For a long time, Arch Calendar's desktop app was Mac-only. That changes today — Arch Calendar is now available as a native desktop app on Windows.

Everything you'd expect from the desktop app is here: Quick Capture (Ctrl + Space), native menus, and the always-on feel of a real desktop app. Just download it from our website and pick up exactly where you left off.

Other Improvements

  • Duplicate & Move with Option(Alt) + Drag — Copying a block to another time slot used to mean duplicating first, then dragging. Now, just hold Option(Alt) while dragging any calendar block — it duplicates and moves in one motion, and the new block opens for editing right away.

  • Recurring events, Guests, and Notes — now editable on mobile — Until now, recurring events, guests, and notes were read-only on the mobile app — to edit them, you had to switch to desktop or web. No more. Set up recurring schedules, add or remove guests, and write notes directly from your phone.
