Reading aids

Tuned to how you read.

Focus Reading bolds the front of each word to guide your eye and set your pace. And full right-to-left layout brings the EPUB and text readers to languages like Hebrew and Arabic, with matching interface translations.

Tilt to Turn · X3<br>On the X3, the built-in motion sensor turns pages with a gentle tilt of the device.

Configurable Buttons<br>Page turns follow the screen orientation, and the side buttons can be disabled entirely.

Enhanced AA & Page Speed<br>Smoother grayscale anti-aliasing and tiled rendering with silent pre-indexing for faster, cleaner page turns.
