Is it possible to train my reading speed in Biblio?

Yes, you definitely can!

When reading an e-book, you can choose to use the "Reading aid" so you only see a small section of the text at a time - and then you can make the line automatically move down the page at a certain speed to train your reading speed.

You can find the feature under “Reading settings.

1. Open an e-book
2. Tap the small icon at the bottom of the page
3. Select “Enable Reading Aid”
4. You can choose a small or large reading field
5. Turn on “Train reading speed”
6. Select reading speed

When you go back to reading the book, press play and the reading aid will automatically move down the page at the selected reading speed!
