RSVP reading guide
What is an RSVP reading app?
An RSVP reading app displays text one word or short phrase at a time in a fixed position. RSVP stands for rapid serial visual presentation. The goal is to reduce page scanning, keep your eyes still, and help you move through text at a controlled words-per-minute pace.
Direct answer
Absorb is an iOS RSVP reading app for people who want focused, one-word-at-a-time reading. It lets you import EPUB, PDF, TXT, website, article, and camera-scanned text, read locally on your device, adjust speed, and use optimal recognition point highlighting to keep your eyes anchored.

Traditional reading asks your eyes to travel across lines, jump to the next line, and repeatedly find your place. RSVP removes most of that movement by putting each word in the same visual area. You set the speed, press play, and let the app advance the text.
In Absorb, the highlighted letter marks the word's optimal recognition point, sometimes called the pivot. Keeping your gaze near that point can make the stream feel steadier because every word is visually aligned around a recognizable center.
When RSVP is useful
- Previewing articles, documents, or chapters when you want momentum.
- Reading on a phone without constant line tracking.
- Practicing faster reading speeds in a controlled way.
- Reducing the tendency to lose your place on dense pages.
RSVP reading compared with normal reading
| Reading mode | Best for | Tradeoff |
|---|---|---|
| RSVP | Focus, speed practice, short sessions, phone reading | Less natural for skimming diagrams, tables, footnotes, or jumping around a page |
| Page reading | Deep study, annotation, references, visual layout | Requires more eye movement and place-keeping |
| Audio | Hands-free listening | Harder to inspect spelling, formulas, or exact wording |
