Flash Reader is back, and better than ever. It read you one word at a time years before that was a trend. On the App Store since 2010, rebuilt from scratch for version 4, and everything happens on your device. Paste it, share it from any app, open a PDF, EPUB or Word file, or point the camera at a page, and you're reading. Every document keeps your place, and a widget, Control Center or Siri takes you straight back in. THREE WAYS TO READ • Flash: one word, one spot, and the pages fly. One letter in red holds your eye. • Chunk: a few words at a time, for when you would rather stroll. • Reader: the whole text, for a look back. Tap to pause. Play picks the sentence back up, so you never lose the thread. SPEED, WITH RECEIPTS Understanding holds to about 350 words a minute, then it slips. Flash Reader starts you at 250, the ruler shows which zone you are in, and your real speed counts the pauses too. Go faster whenever you like; the ruler tells you what it costs. Little words pass quickly, long or rare ones get a beat more, and a full stop gets its pause. Rest breaks when you want them. READ ANYTHING, START ANYWHERE • Copy anything, anywhere. Tap the clipboard chip, or the button in Control Center, and it flashes. • Share text, a web page or a link from any app: articles, mail, messages, notes. • Open PDF, EPUB, Word and text files from the Files app. • Point the camera at a page, or pick a photo or a screenshot. The text is read on your device. • Drop in a link and get the article, with none of the clutter around it. • Say "Flash my clipboard" or "Resume reading" and Siri does the rest. • Every document keeps its place, its mode and its speed. • Search, sort and rename. Deleted documents wait in Recently deleted. BACK IN ONE TAP Continue Reading and Streak widgets for the Home and Lock Screens. Flash clipboard and Resume reading in Control Center. Stats keep words read today, your streak and your real speed, pauses and all. ROOM TO READ Four themes (Paper, Ink, Sepia and High Contrast), a choice of fonts, an adjustable word size, and reading in landscape. On iPad, the library sits beside the reading view and a keyboard drives both. Designed for iPhone Duo: open it and the page unfolds beside the words. The whole app speaks 50 languages. FREE AND PRO Free to start. Text you paste, copy or share reads free, forever, at full quality: every mode, every speed, every theme, links, TXT and Markdown files, and three documents on the shelf at a time. Pro opens PDF, EPUB, Word, RTF and HTML files, scans and photos, and an unlimited shelf. One purchase covers iPhone and iPad, and your library and your place travel between them through your own iCloud. Choose Pro by the year with a 14-day free trial, by the month, or pay once and keep it. Annual and monthly Pro renew automatically until cancelled in your Apple Account settings, at least 24 hours before the period ends. No account. No ads. No analytics and no tracking. COMING BACK? Your books, your speed and your bookmark come along from the old version. If you bought Pro inside Flash Reader before, it is still yours: Restore purchases in Settings brings it back on any device. If you bought the separate Flash Reader Pro app, write to us and we will sort it out. More formats and modes are coming as free updates. Flash Reader 4 needs iOS 26 or later. On an older iPhone or iPad, the App Store keeps offering the last version that runs there.
