Quick answer

Widget, which shows the time in German words based on fractions

This app allows you to configure a widget that displays a digital clock with the time written in German words below it. The word clock is based on quarter-hour intervals, a style particularly common in Southern Germany. In addition to the quarter-hour basis, a 5-minute basis is also available. The word clock’s style and font can be customized. The widget’s transparency is fully adjustable. Additionally, both the digital clock and the word clock displays can be toggled off individually. Since this app only makes sense in German, there ist no English locale.

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.
