What you can change

  • Theme: Light, Sepia, Dark or Black. Turn on Match my device to follow your phone’s light or dark mode.
  • Font: Book (a serif font made for long reading), Clean (a simple sans font) or Easy-read (extra-clear letters).
  • Text size: A− and A+, from 14 to 30 pixels.
  • Line spacing: Compact, Normal or Relaxed.
  • Page width: Narrow, Medium or Wide.
  • Text alignment: Left or Justified.
  • Swipe: turn on swiping left and right to change chapter on phones.

Changed too much? Tap Reset to default at the bottom of the panel.

The moon button in the header switches quickly between light and dark without opening the panel.

My settings disappeared

Settings are kept in your browser’s storage. They reset if you clear your browsing data, use a private window, or switch to another browser or device.

Settings for different situations

  • Reading at night: choose Dark or Black, and turn your phone’s brightness down. Black saves battery on phones with OLED screens.
  • Long sessions: Sepia with the Book font and Relaxed line spacing is gentle on the eyes.
  • Dyslexia or tired eyes: Easy-read with a bigger text size (A+) and Left alignment (justified text adds uneven gaps between words).
