Cool [APP]OpenSpritz for speed-reading epup with new Spritz technology

1st of all. Im not an Dev and an english speaking person. But I want to share an awesome App with the new cool speedreading technology "Spritz".
There is an GitHub Project called https://github.com/OnlyInAmerica/OpenSpritz-Android.

I've grabbed from GitHub the source an packed in an app.
So you can read EPUP with the spray idea.
The following features are included:
- Adjust the speed (WPM)
- Pause function
- forwqard backward rewind (with chapter)
- Invert mode

For opening of EPUP it is more practical to look for a file explorer out the book and then open the app. Within the app you can also open books.
Note: Long words will be displayed double-spaced.

Who wants to test the app can download the APK for Android here
