After one year of work and rigorous testing, we now present the all new Auto Dark Mode X. It's now a future proof application that is made to be robust, while still carrying its light-weight and resource friendly characteristics.

First I would like to thank our new team member @Spiritreader. He has done an amazing job with the backend of Auto Dark Mode X and he invested many hours of valuable time in this project. He will continue to work actively on Auto Dark Mode.

Another good news: Auto Dark Mode is now also available on the Windows 11 Store as unpackaged installer.

IMPORTANT NOTE: Please first uninstall the old version of Auto Dark Mode, due to some under the hood changes that could cause errors.

Changes in Version 2.1.1:

This update was re-released as Version 2.1.1. Some really important Bugs are now fixed, so please upgrade your Auto Dark Mode-App, even if you already installed the original 2.1 release.

Changes in Version 2.1:

  • We have a new name! From Auto-Night Mode to Auto Dark Mode.
  • Instant theme switch after starting up or waking up your Computer. Finally! (#20)
  • You can now also choose minutes for your sheduled times. This also results in more accurate sunrise and sunset times. (#16 and #14)
  • Support for different languages. At the moment the program is translated into english, german and polish. Thanks to @xmcgamer0x for the contribution.
  • The Location-Time now updates weekly instead of monthly. The transitions between seasons are changing the sunrise and sunset-times pretty often.
Changes for Windows Version 1903:
  • Accent Color can now be used for the Taskbar and other System Elements while dark mode is activated. With the sheduled switch to the light System-Theme, the App automatically turns off Accent Color and turns it back on, when the night comes.
  • Current theme is now oriented on App-Theme when the System-Theme is set to Always dark/light.
More stuff
  • Setup now uses a certificate. Hopefully Windows Smartscreen will like my program in future.
  • I tried to fix some Bugs with the theme switch for Microsoft Edge. Now it should use the correct theme. (#19)
  • New tooltip for deactivated Options when Windows 1903 is not installed.
  • Current Theme detection was not working in Version 2.0. Nobody noticed it, but now it works 😆
