Size chart Flow
The Flow should sit comfortably on your finger, which is why three sizes are available.
You can choose between SMALL, MEDIUM and LARGE .
Please measure the circumference of your index finger at the top joint:
If the circumference is less than 4.7 cm, please choose SMALL. If it is greater than 5.2 cm, please choose LARGE. For all index finger circumferences in between (4.7cm to 5.2cm), please choose MEDIUM.
Tip:
If you don't have a flexible measuring tape, you can simply take a thread, shoelace, or cord, wrap it around the joint, and then read the length in cm on a ruler, set square, or folding rule.

THE principle
Eye-tracking
Reading begins with your eyes. With the Bookhoover as an ergonomic finger attachment, you guide your eyes controllably through the text to avoid unnecessary eye movements such as skipping back in the text.
Your eye muscles don't tire as quickly, you increase your concentration, and thus your reading speed.
