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. Upgrade to Pro for unlimited books, speeds up to 1000 WPM, every color, background, and anchor shape, and the full Statistics dashboard. Celeris Pro is available as a monthly or annual subscription.
