We combine a passion for books with years of software development experience to create an app tailored to you.
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, and instant search.
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.
Some stories need more than one book. Group their volumes into a series, arrange them your way, and find every title together in a cover gallery. Create as many series as you like.
Choose a crackling fire, gentle rain, or a storm and settle into your reading nook. Each sound has its own animated scene, with Niblio reading beside you. Set the volume, open your book, and enjoy your little retreat.
Reading streaks, annual goals, pages per day, average speed, reading calendar, and analysis by genre. Know your habits and improve every week.
Point the camera at the barcode of any book or search by title, author or ISBN. Niblio accesses a catalog of more than 122 million books to instantly get the cover, author, publisher and all the details.
Your library is stored on your device, with no account required. Searches, covers, purchases and error diagnostics use external services, as explained in our privacy policy.
Lent a book and don't remember to whom? Record in Niblio who has your books and which ones have been lent to you, with complete history.
If you have doubts about which one to start, Niblio helps you by picking one of your pending books to save you from indecision and get you reading.

A few useful things to know about Niblio, your books and your data.
Niblio is a book tracker and personal library app for iOS and Android. Catalog books, organize shelves, scan ISBNs, log reading sessions and explore your reading statistics.
The free download includes every feature for up to 100 books. Niblio Unlimited removes the book limit with a one-time purchase. The applicable price is displayed in the app before purchase. There are no subscriptions or ads.
No. Your library, notes and reading sessions are stored locally on your device. Book and cover searches, purchases and error diagnostics use external services, as explained in the privacy policy.
You can use your local library offline. Searching external catalogs, downloading covers and managing purchases require an internet connection.
Use the backup export and import features. Save a copy outside your device before replacing or resetting it. Your library is stored locally; do not assume a cloud copy already exists.
Yes. Search by title or author, or enter the details manually. A book does not have to appear in the catalog to be part of your library.
Niblio is available in Spanish, English, Galician, Catalan and Portuguese.
If you have any feature requests, technical support questions, or just want to say hi, write or follow us.
Download Niblio completely free of charge and try all features without exception.
The free version has a generous limit of up to 100 books.
We know you don't like subscriptions.
Neither do we, that's why Niblio has none. If you ever need to register more than 100 books or simply want to help make the project sustainable, there is Niblio Unlimited, a one-time payment and that's it.
