Three sizes

Small for one big number, medium for the next three, large for the whole list. Pick your real-estate.

Native WidgetKit

Built with SwiftUI + WidgetKit. Lives on your desktop, refreshes daily, never opens a browser tab.

Local-first

Every countdown is stored in an App Group container on your Mac. No login, no server, no telemetry.

Color & emoji

Pick a color and emoji per countdown. Recognise them at a glance from your desktop.

Free forever

MIT licensed. No subscription. No ads. If it saved you a sticky note, drop a buck in the tip jar.

Cmd+N to add

Open the host app, hit ⌘N, type a name, pick a date, done. Widget updates instantly.

Install

Stop checking your calendar. Just glance.

DueIn is open source. Run these three commands and you'll have a fresh DueIn.app on your machine in a minute or two.

Prerequisites: Homebrew · Xcode 15+ (the build script installs xcodegen automatically). 
$ git clone https://github.com/bendawg2010/DueIn.git
$ cd DueIn
$ ./scripts/build.sh
  1. The script installs xcodegen, generates the Xcode project, and runs xcodebuild in Release.
  2. Move build/Build/Products/Release/DueIn.app into /Applications.
  3. Launch it once, then add the widget from System Settings → Wallpaper → Edit Widgets (or right-click the desktop on macOS 14+).
