PDF reading guide
PDF speed reader for iPhone
PDF speed reading is useful when a PDF contains extractable text and you want to move through the prose without constantly pinching, zooming, or tracking lines on a small screen. It is less useful when the PDF depends on layout, scans, charts, forms, or side-by-side references.
Direct answer
Absorb can be used as a PDF speed reader on iPhone for supported text-based PDFs. It imports PDF files and presents extracted text with RSVP pacing, ORP highlighting, reading stats, and local-first handling of imported content.
Download Absorb on the App StoreWhen PDF speed reading works well
- Articles, essays, reports, and other text-heavy PDFs.
- PDFs where the main value is the words, not the exact visual layout.
- Documents you want to preview quickly before deeper review.
- Reading sessions where iPhone screen size makes page scanning tiring.
When normal PDF reading is better
| PDF type | Why RSVP may struggle | Better mode |
|---|---|---|
| Scanned PDFs | Text may not be available for clean extraction. | OCR or page reading. |
| Research papers | Tables, equations, citations, and figures often need context. | Mix RSVP with page review. |
| Forms and legal documents | Layout and exact clauses matter. | Careful page reading. |
| Slide decks | Meaning often comes from spatial arrangement. | Visual review. |
Practical workflow
- Import a text-based PDF into Absorb.
- Use RSVP to read the body text at a comfortable WPM.
- Pause or switch context for tables, equations, citations, and figures.
- Use stats as a habit signal, not as proof of comprehension.
Caveats
No PDF speed reader can make every PDF behave like a clean ebook. Extraction quality depends on the PDF. Absorb is a focused RSVP reader, not a PDF editor, annotation suite, OCR tool, or legal review tool.
