Store listing

Full description
📖 Lumen is a calm, beautifully designed reading app that turns your phone into a personal library — a place to read PDFs, open EPUB books, discover thousands of free classics, and finally build the daily reading habit you've been meaning to keep. At the heart of Lumen is a distraction-free ebook reader that handles both PDF documents and EPUB books with the same care. Whether you're opening a study PDF, a research paper, a novel you sideloaded, or a public-domain classic downloaded inside the app, Lumen renders it beautifully with reflowable text, adjustable margins, custom line spacing, and a font size you can dial in with a single slider. Choose from elegant reading typefaces like Lora, Merriweather, EB Garamond, Inter, and Bitter, and swipe or scroll — whichever way you like to turn the page. ✨ The reader ships with six handcrafted themes built for real reading light: a warm Classic, a clean Modern, a moody Dark Academia, a deep Midnight, a nostalgic Sepia, and a soft Pastel. There's a true dark mode for late-night reading without eye strain, and the app remembers your position in every book so you can close it mid-sentence and pick up exactly where you left off. 🌙 Highlighting is where Lumen quietly shines. Select any passage, mark it in one of five colors, and add a personal note — a thought, a translation, a reminder of why the line hit you. Every highlight lands in a searchable notebook that spans your whole library. When you find a sentence worth sharing, one tap turns it into a beautifully formatted quote card you can post to Instagram, X, WhatsApp, Facebook, or send to a friend — a tiny ritual for the words worth remembering. 💛 Discover more to read through a built-in store that connects to Project Gutenberg, Open Library, and Standard Ebooks — three of the largest catalogues of free public-domain books online. Browse over seventy thousand titles, from Jane Austen and Charles Dickens to Dostoyevsky, Sherlock Holmes, Shakespeare, and the great essayists of every century. Every book downloads for offline reading, forever, at no cost. 📚 Lumen turns reading into a habit you can actually see. A calendar heatmap tracks the days you opened a book, a streak counter rewards consistency, and detailed statistics show how many minutes and pages you've read this day, week, month, or year — and how long you've spent in each individual title. Gentle daily reminders let you pick a time and the days of the week you want a nudge, with a small library of inspiring messages or a custom one you write yourself. 🔥 Privacy is built in. There is no account, no sign-up, no cloud, and no tracking of what you read. Your books, highlights, bookmarks, and reading time live on your phone and nowhere else. Once a book is downloaded, the app works fully offline — perfect for planes, trains, and long quiet weekends. 🔒 Lumen speaks twelve languages, including full right-to-left support for Arabic, and translations covering English, Spanish, French, German, Italian, Portuguese, Russian, Hindi, Chinese, Japanese, and Turkish. 🌍 The whole app is intentionally quiet. Warm colors, careful typography, and a small number of well-considered features are here to make reading feel like a moment for yourself — not another task in a busy day. Whether you're rereading a favorite classic, finishing a novel you started years ago, importing academic PDFs for study, or starting your very first reading streak, Lumen was built to be the reader that treats your books with the same care you do. ✨
