SpeederReader — Features

Speed Reading (RSVP)

Rapid Serial Visual Presentation flashes words one at a time at a fixed position on screen. Your eyes stay still, eliminating the back-and-forth saccades that slow traditional reading. Most people can comfortably reach 2–3× their normal pace within a few sessions.

Speed range: 50–750 WPM Default: 250 WPM Controls: −25 / +25 WPM buttons, always visible while reading

Optimal Recognition Point (ORP)

Each word is split at its optimal recognition point — the letter your brain uses as an anchor when reading. For odd-length words this is the exact middle letter; for even-length words it is the left-of-center letter. That letter is highlighted in gold and aligned to the horizontal screen center so your gaze never shifts.

Flow Mode

Natural reading is not metronomic. Flow mode detects punctuation (., ,, !, ?, ;, :, —) and doubles the display time for those words, giving your brain the natural pause it expects at the end of a clause or sentence. Toggle on/off from the speed controls bar. On by default.

Context Strip

A paragraph-level view sits above the RSVP word display, showing the surrounding text with the current word highlighted. This keeps you oriented in the narrative and helps comprehension — you always know where you are in the sentence.

Word Navigation

When paused, left ← and right → arrow buttons appear below the context strip so you can step forward or backward one word at a time. Useful for re-reading a confusing phrase or reviewing what you just read.

Dictionary Lookup

Tap look up word when paused to look up the current word on Dictionary.com:

• Web: opens in a new browser tab
• iOS / Android: opens an in-app WebView so you never leave the reader

Progress Saving

Your reading position is saved automatically whenever you turn a page, pause, or jump. When you reopen a file, SpeederReader offers to resume from where you left off. Progress is stored locally on-device — no account required.

Page Jumping

Tap the page indicator in the bottom bar to jump to any page. Jumping saves progress and auto-resumes reading.

Supported Formats

All parsing is 100% on-device. Your files are never uploaded anywhere.
