Librio is an all in one personal library app built for people who want complete control over their media without sacrificing privacy, performance, or customization. Librio lets you listen to audiobooks, read e books and comic books, enjoy your personal music collection, and watch movies and videos, all from one clean, organized, and easy to use app. You simply add your already legally purchased content, and everything stays stored locally on your device at all times. Your media never leaves your phone, and your data is never tracked, collected, analyzed, or shared.

Librio was created with three core goals in mind: convenience, privacy, and customizability. Every feature in the app exists to support those goals without unnecessary complexity or hidden behavior. The interface is designed to feel modern and intuitive, making it easy to jump in and start using your library immediately, while still offering powerful tools and settings for users who want deeper control.

The app supports a wide range of file types and is optimized to handle large libraries smoothly. Librio automatically scans your content, saves progress reliably, and provides fast, responsive navigation across all categories. Browsing large collections feels quick and organized, even with thousands of files.

Profiles are a core feature of Librio. You can create multiple profiles on a single device, each with its own completely independent library, settings, themes, playlists, progress tracking, and custom profile picture. This makes Librio ideal for shared phones, tablets, families, or users who want separate setups for different preferences. Switching profiles is instant, and each profile only ever sees its own content and uses its own settings.

Customization is a major focus throughout the app. You can personalize the entire Librio experience with themes, font selections, adjustable font sizes, and an app scale slider that lets you resize the entire interface for comfort or accessibility. A full dark mode is available for low light environments. Playlists can be created and edited across supported content types, allowing you to organize audiobooks, music, and other media exactly how you want.

Audio playback in Librio is highly configurable. You can fine tune your listening experience using custom equalizers, an audio normalizer, playback speed controls, crossfade, volume boost, and a built in sleep timer. The sleep timer is perfect for nighttime listening, automatically turning off the screen and stopping playback if you fall asleep.

Reading features receive the same level of attention. E books and comics include customizable reading settings that allow you to control how your content looks and feels, making long reading sessions more comfortable. On larger devices and folding phones, Librio supports side by side reading, allowing pages to be displayed next to each other for a more immersive experience.

Getting started with Librio is simple and transparent. After installing the app, you can rename the default profile or create additional profiles as needed. Using your file explorer, you place your content into clearly organized Librio profile folders for audiobooks, e books, comics, music, and movies or videos. When you return to the app, Librio automatically scans and loads everything with no manual importing or setup required.

All settings in Librio are saved on a per profile basis, including appearance options, audio preferences, reading settings, playlists, progress tracking, and profile images. Each profile remains fully independent, ensuring a clean and predictable experience.

Librio is designed to be a lightweight, offline friendly alternative to subscription based platforms. There are no ads, no accounts required, no internet dependency, and no hidden analytics. The app is built to be fast, stable, and respectful of the user, with updates focused on performance, usability, and giving users even more control over their personal library.
