Everything you need to
enjoy reading

Niblio turns your phone into a complete log, giving you simple and powerful tools to organize your collection without compromising your data.

Visual library and bookshelves

Organize your books on custom shelves. Define them based on your real physical locations (like "Living Room" or "Bedroom") to know exactly where they are physically, or use them to categorize as you wish. Easily access your collection with sorted lists, status filters (reading, read, pending), and instant search.

Read. Pause. Resume.
Niblio remembers for you

Start a reading session with a single tap. The timer tracks your exact reading time, you indicate which page you finished, and Niblio does the rest: calculates your speed, estimates when you will finish the book, and builds your reading history day by day.
