About this app

ShelfSignal is a calm and thoughtful reading companion designed to help you build a personal library that grows with every book you read. From the moment you open the app, your shelf is completely empty—there are no sample books, pre-filled content, or unnecessary distractions. Everything you see belongs to you.

Keep track of your reading journey by recording your progress, logging reading sessions, and saving memorable quotes with page numbers and personal tags. Organize books into meaningful stacks, set gentle reading goals, and explore your own reading habits through clear, easy-to-understand statistics that reflect your pace over time.

Built around a clean, dark interface inspired by a modern card library, ShelfSignal makes it easy to move through your collection while keeping the focus on reading itself. All information is stored locally on your device, giving you a private space to preserve your library, favorite passages, and reading history.

Whether you read every day or only when you find a quiet moment, ShelfSignal helps you stay connected with the books that matter, remember the ideas that inspire you, and create a lasting record of your reading experience.
