Celeris: Speed Reading
Read faster, word by word
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.
