Focus Box is a simple, powerful overlay tool that helps you focus while reading long texts on tablets or smartphones. It creates a customizable transparent box that floats above all apps; ideal for reading EPUBs, PDFs, or long web articles without distractions.
Originally developed for my personal use while reading novels on a Samsung tablet, Focus Box is now open source and available for anyone looking to improve their reading experience.
