RSVP stands for Rapid Serial Visual Presentation. Instead of scanning a full line, you hold your gaze in one place while words appear in sequence. The idea sounds simple, and the reading literature gives it some support. Eye movements take time. At the same time, comprehension still sets a ceiling.
RSVP Reader pairs that format with ORP highlighting. The App Store listing says words appear one at a time at your chosen speed, with ORP highlighting, across three reading modes.
What RSVP improves
The Rayner review says normal reading depends on eye movements, language skill, and comprehension. RSVP can help when page navigation slows you down more than the ideas do. That often means short articles, familiar nonfiction, and first-pass reading.
It can also help people who want to reduce subvocalization, because the pacing changes the rhythm of the reading session.
What RSVP does not magically solve
The same review says there is a tradeoff between speed and comprehension. The PLOS ONE study on RSVP also found that measured rates shift a lot with masking, memory load, context, and eye movement demands. So RSVP is not a magic setting. Dense material still needs judgment, and sometimes it needs a slower mode.
That is why reading modes belongs next to this page.
The best way to start
Start with a baseline on the reading speed test. Then use RSVP on material you already understand well enough to judge when the pace is too high. If you are also weighing other apps, RSVP Reader vs Outread is the most direct category comparison.
