Read More. Scroll Less. Do you have a huge stack of books you want to finish, or long documents you need to get through for work? Reading on a phone screen can quickly make your eyes tired, and it is incredibly easy for your mind to wander. Whether you want to read more books, improve your focus, try speed reading, or build a calm self-care routine, this Rapid Serial Visual Presentation app makes reading easy. Instead of forcing your eyes to scan back and forth across a page, we bring the words directly to you. Our reader flashes words on your screen one at a time, perfectly centered. Because your eyes stay in one place, you stop accidentally re-reading the same lines and you never have to scroll. You just look straight ahead and let the story flow. You will train your brain to lock in on the text. Over time, you will naturally cut out distractions, reduce eye strain, and comfortably double your reading speed. The app is designed for readers who find traditional pages overwhelming or distracting. By showing one word at a time in a clean, focused reading view, it may be helpful for people who have difficulty staying focused, including some readers with ADHD, dyslexia, or attention challenges. Adjustable reading speed, minimal visual clutter, and short daily sessions make it easier to start reading, keep momentum, and enjoy books without the distractions of a typical ebook page. RSVP speed reader app Cheetah is here for you. What You Can Do: Bring Your Own Reading: Easily open your own PDFs, ePubs, and text files right in the app. Send from the Web: Found a long article on your phone? Use the share button to send it to the app with just one tap so you can read it instantly. Free Books: Don't have a file ready? Dive into free classic books and Wikipedia articles built right in. Zero Scrolling: Give your thumb a rest. The words come to you, which means no more swiping and no screen fatigue.
