Spritz alternative for iPhone RSVP reading
If you are looking for a Spritz-style reader, you probably want rapid serial visual presentation: words shown one at a time, a highlighted pivot letter, and adjustable reading speed. Absorb is built for that style of focused reading on iPhone.

- Adjustable WPM: Speed should match the text, not just a marketing number.
- ORP or pivot highlighting: A visual anchor helps fixed-gaze reading feel steadier.
- Import breadth: EPUB, PDF, TXT, website, article, and camera scan support matters if you want to read your own library and web reading queue.
- Private reading: A reader should be clear about what stays on device and what is shared.
- Simple controls: RSVP works best when play, pause, speed, and progress are easy to reach.

How to evaluate it honestly
- Pick a plain prose chapter or article.
- Read one section at a comfortable WPM in Absorb.
- Pause and explain the section in your own words.
- Increase speed only if recall and comprehension remain solid.
- Switch back to page reading for tables, diagrams, or passages that need close review.
Who Absorb is for
Absorb is for readers who want a clean, private, phone-native RSVP app rather than a web widget or general document manager. It is especially useful when you want to read imported prose without visually wrestling with the page.
Who should choose something else
Choose a full PDF editor, academic annotation app, or traditional ebook reader if your main need is markup, layout fidelity, citations, or side-by-side comparison. Absorb's strength is focused RSVP reading.
