Quick answer

Mirror applications for HUD display with horizontal flip.

F-Droid repository metadata

Middor is a free and open-source Android application for mirroring apps on your device. With built-in support for horizontal flip and 180° rotation, Middor can be used to:
  • Display apps on a HUD
  • Project content onto a car windscreen (e.g. Google Maps navigation)
  • View mirrored images and videos
Middor only supports devices running Android 14 QPR2 or higher, as it relies on the single app screen sharing feature. For more details, see Android 14 - App Screen Sharing: https://developer.android.com/about/versions/14/features/app-screen-sharing For usage instructions, see https://github.com/nktnet1/middor/discussions/2 Permissions
  • SYSTEM_ALERT_WINDOW: to draw a mirror overlay on top of other apps
  • FOREGROUND_SERVICE: to run the mirror service continuously while the overlay is active
  • FOREGROUND_SERVICE_MEDIA_PROJECTION: for capturing the screen content of the underlying app
  • POST_NOTIFICATIONS: (optional) to display the mirror service notification with additional actions

What’s new

## Changes

- feat: setting to remove system bars

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.

Data safety

  • Every file is checked against its published SHA-256 before it is listed.
  • Files are scanned for malware on every update.
  • The permissions each app requests are listed on its own page.
  • Read the full safety policy for how we test, flag, and delist files.
