The Arch Calendar desktop app is now available on Windows. It supports all the same desktop features as Mac β notifications, reminders, snooze, and more.
During installation, you may see a Windows SmartScreen security warning like the one below.
This does not mean Arch Calendar is unsafe. Windows SmartScreen is a built-in security feature that flags apps that haven't been widely downloaded yet. Well-known productivity apps like Obsidian and Logseq receive the same warning. Arch Calendar is digitally signed and safe to install.
Step 1. Click "More info" On the blue SmartScreen screen, click the "More info" text.
Step 2. Click "Run anyway" Click "Run anyway" to proceed with the installation.
As more users download the app, this warning will disappear automatically.
π‘ Why does this warning appear? Windows SmartScreen uses a reputation system based on download volume. Newly released apps start with zero reputation, regardless of whether they are digitally signed. Even popular apps like Obsidian and Logseq receive this warning with every new version β it's a well-known industry-wide issue.
