One-word-at-a-time reader for iPhone
A one-word-at-a-time reader displays text in a fixed position, usually at a chosen words-per-minute speed. This technique is called rapid serial visual presentation, or RSVP. It can make reading on a phone feel more direct because your eyes do not need to scan across lines.
Direct answer
Absorb is a one-word-at-a-time reader for iPhone. It uses RSVP pacing, highlights the optimal recognition point, imports EPUB, PDF, TXT, website, article, and camera-scanned text, supports multilingual books, tracks reading stats, and is designed as a local-first reader for imported content.

Normal reading asks your eyes to move across a page, return to the start of the next line, and recover your place after interruptions. A one-word reader keeps the target fixed. The app advances the text, and you control the speed.
Why ORP highlighting matters
In Absorb, one letter is highlighted as the optimal recognition point. This pivot helps align words around a consistent visual anchor, which can make the stream easier to follow than plain centered words.
Best and worst fits
| Good fit | Use caution |
|---|---|
| Books, articles, essays, websites, scanned pages, and text-heavy documents. | Tables, code, poetry, equations, footnotes, and visual layouts. |
| Focused reading sessions on iPhone. | Research tasks that require jumping between sections. |
| Practicing faster reading while tracking WPM. | Material where exact wording must be checked carefully. |
Caveats
One-word-at-a-time reading can help reduce scanning and maintain pace, but it is not automatically better than page reading. Choose the mode that matches the material. Slow down or switch modes when comprehension, layout, or precision matters more than momentum.
