Read faster without skimming. Celeris uses RSVP (Rapid Serial Visual Presentation) to flash one word at a time in a fixed spot on screen, so your eyes never waste time scanning across lines. The result: you move through books and articles noticeably faster, with your focus locked in one place. Bring your own reading. Import EPUB and plain-text files, or paste in any web article and Celeris converts it into a clean, distraction-free read. The fastest way in is the share sheet — tap Share on a book or link in any app and send it straight to your Library. TWO WAYS TO READ • RSVP — a single word at a time in a fixed focus point, with a color-highlighted anchor letter to keep your eyes locked on. The fastest way to read. • Coasting — several lines glide gently upward past a highlighted focus line, auto-advancing at your pace. More context per glance when you want it. Switch between the two instantly from Quick Settings, without leaving your book. BUILT FOR REAL READING • Never lose your place — your position is saved automatically in every book. • Tap any word to jump straight to it, rewind 10 words, or restart the paragraph. • Jump to any chapter from the Table of Contents. • Highlight passages with a long-press-and-drag, add notes, and revisit them all later. • Fine-tune your pace: separate pauses for sentences, punctuation, long words, and paragraphs keep fast reading feeling natural. MAKE IT YOURS • Reading speed from a comfortable pace up to 1000 WPM. • Choose your accent color, page background (White, Off-White, Bone, Old Scroll, Pinkish), and anchor shape (Line, Dot, Heart, Diamond, Chevron, Bolt). • Adjustable font size for RSVP and Coasting alike. SEE YOURSELF IMPROVE • Track total reading time, words read, average pace, and your longest session. • Daily and weekly activity, a reading-activity heatmap, and a pace-over-time chart. • Build a daily reading streak and beat your best. FREE & PRO Celeris is free to start: keep up to 3 books, read up to 400 WPM, and track your time and streaks.
