About this app

Read at the speed of thought, and keep your highlights and notes with the text.

Refract is a speed reader for Android. It shows a document one word at a time (RSVP, rapid serial visual presentation), or as text with your place marked, and keeps your library, highlights, notes and progress on your phone. No account, no sign-in, no analytics, no ads.

RSVP READER
• Each word appears in the same spot with one letter in your accent colour, so your eyes stay on one place.
• Read at 10 to 2,000 words per minute. Speed presets, a warm-up and an optional gradual speed-up are there if you want them.
• Pacing follows word length and punctuation, or gives every word the same time.
• Show the neighbouring words or the sentence around the word, and choose the guides, fonts, sizes and colours.
• Tap, swipe, volume keys or a keyboard to play, pause, step and change speed.

MORE WAYS TO READ
• Kinetic shows the full text with your current word marked. Tap a word to continue from there, long-press to highlight it, and add notes.
• Other views: guided pointer, auto-scroll, book pages, ticker, and plain reading with a marker for your place.
• PDFs and web articles also have an Original view: the PDF's pages, or the live web page.
• Contents, search inside the document, bookmarks and go-to.
• Read aloud with your phone's speech engine, highlighting the spoken word where the engine allows. It can carry on with the screen off, and there is a sleep timer.

ADD WHAT YOU READ
• PDF (including password-protected), EPUB, MOBI and AZW3 without DRM, FB2, DOCX, PPTX, ODT, RTF, HTML, Markdown and plain text. Encodings are detected.
• Web articles and PDF links: paste a link or share one from your browser.
• Pasted text, the clipboard, a whole folder, or text selected in another app ("Speed-read with Refract").
• Free classics from Project Gutenberg and articles from Wikipedia, with its CC BY-SA credit added.
• A built-in browser: open any page, then read it or just the part you select.
• Clean-up: page numbers, running headers and footers where Refract can spot them, and menus and sidebars on pages you add.

YOUR LIBRARY
• Shelves for continue reading, unread, finished, favourites and archived, plus your own collections and tags.
• Sort and filter, and search titles, authors, tags or the text itself. Cards show the cover, time left and progress.
• Notebook: your highlights and notes in one place, exported as Markdown, text, CSV, JSON or HTML, or as a quote card.
• Vocabulary with look-up, flashcards and sets. On-device previews and quizzes made from the text.
• Back up to a file you choose, automatically if you like, and restore it on another phone.

TRAIN
• 28 exercises for attention, eye movement, perception, memory and speed, such as Schulte tables and word flash.
• Speed and comprehension tests, practice passages, 12 lessons and a 30-day programme.
• Progress, daily goals, streaks, achievements and an optional reminder, all counted on your phone.

LOOK AND FEEL
• Light, Dark (true black) or your system's setting, with seven accent colours and a Wallpaper colour on Android 12 and later.
• Reading themes, nine fonts and colour-vision options.
• Layouts adapt to tablets and landscape screens.

PRIVATE BY DESIGN
• No accounts, no analytics, telemetry or crash reporting, and no ads.
• Your library stays in private app storage on your phone, which other apps can't read, and is not copied to cloud backup.
• Refract goes online only when you ask: for web pages and PDFs you add, Project Gutenberg, Wikipedia, and pages you open in the built-in browser or the Original view.
• Read aloud runs in your phone's speech engine. If you choose a voice that needs the internet, your engine sends it the text.

WHO IT'S FOR
• Professionals, students and researchers, and anyone whose reading list keeps growing.

SUBSCRIPTION
• Use everything for 24 hours, then subscribe monthly or yearly in Google Play to keep reading and training. Cancel any time; your library stays yours.
