Full description
Caff is a speed reader for your own EPUB books. It shows one word at a time, right where your eyes already rest, so you can read faster without losing your place — or your comprehension. Each word is anchored on its optimal recognition point and tinted at the center, so your eyes stop darting across the page and simply take the words in. Choose a pace that suits the moment, anywhere from a gentle 100 words a minute to a brisk 1000, and let the book come to you. Import any EPUB from Files, and Caff remembers exactly where you stopped in every book. HOW IT FEELS - Tap the center to play or pause - Tap left or right to step back or forward a word - Press and hold an edge to scrub through the book - Swipe to jump a sentence at a time MADE TO FIT YOU - Reading speed from 100 to 1000 words per minute - Adjustable word size and seven focus-point colors - Dark, Light, and Sepia themes - A sleep timer that pauses reading for you - Turn sideways to see the words on either side for extra context FIND YOUR PLACE - Bookmarks, a table of contents, and full-text search - Step back and forward through everywhere you've jumped - Your position is saved automatically, book by book PRIVATE BY DESIGN - Your books and your reading stay entirely on your device. No account, no tracking, nothing to sign up for. Caff turns the reading list you keep meaning to finish into one you actually do.
