Find the page you need, fast
IT books are reference books. The reader is designed for jumping between chapters, looking up a command and coming back.

The whole book on one panel
Every chapter and section is one click away. The section you are reading is highlighted, and its name stays in the top bar so you always know where you are.
- Chapters and sub-sections from the book itself
- Current section shown while you scroll
- Progress bar and page counter at all times

Search inside the book
Looking for that one flag or config file? Type it in. Results show the surrounding text and the page, so you can tell which match you want before you jump.
- Full-text search in PDF and EPUB
- Matches highlighted in context
- Bookmarks for the pages you return to

Late-night reading, easy on the eyes
Choose light, sepia or dark. Zoom PDF pages or change the EPUB text size, then go fullscreen and leave everything else behind.
- Light, sepia and dark themes
- Zoom for PDF, text size for EPUB
- Fullscreen, keyboard arrows and swipe to turn pages
EPUB that fits the screen in your hand
On phones the reader opens the EPUB edition, so text and code blocks reflow to the screen instead of making you pinch and zoom.
