Breu - Science-Backed Speed Reading for iOS

See RSVP Technology in Action

Watch how words appear at the Optimal Recognition Point (ORP), keeping your eye fixed while eliminating inefficient saccades.

Fixed Eye Position

No eye movement needed

Instant Recognition

Words appear at optimal point

Adjustable Speed

200–1000 WPM range

Intelligent Reading Technology

Every feature is designed around proven cognitive science principles

Optimal Recognition Point

Words are centered at the precise point (35% from the start) where your brain recognizes them fastest, based on extensive eye-tracking research.

Adaptive Word Timing

The algorithm automatically adjusts display time based on word length, complexity, and frequency—just like your natural reading patterns.

Smart Punctuation Pauses

Scientifically calibrated delays at commas, periods, and paragraph breaks mirror natural semantic processing times.

Word Frequency Analysis

Based on the Corpus of Contemporary American English (COCA), common words display 25% faster to match your brain's recognition speed.

Cognitive Load Balancing

Automatically slows for numbers, proper nouns, and long words to prevent cognitive overload and maintain comprehension.

Focus-Optimized Themes

Three carefully designed color schemes (Light, Sepia, Dark) reduce eye strain and enhance concentration during extended reading sessions.

Grounded in Cognitive Science

Breu isn't just fast—it's scientifically validated

RSVP Technology

Rapid Serial Visual Presentation has been studied since the 1970s. Research consistently shows 2-3x speed improvements with maintained comprehension when eye movements are eliminated.

Eye Movement Research

Rayner et al. (2006) demonstrated that 80% of reading time is spent on saccades (eye movements). RSVP eliminates this inefficiency entirely.

Word Recognition Studies

The 35% ORP position is based on decades of research by Rayner & Duffy (1986) on optimal visual word recognition points.

Semantic Pause Timing

Pause durations at punctuation are calibrated to match natural syntactic processing times documented in psycholinguistic research.

Peer-Reviewed Research

Every feature backed by published scientific literature

Rayner et al. (2003) — Eye Movement Control

Demonstrated that eliminating return sweep through RSVP increases reading speed by 25-30% without comprehension loss.

Traditional vs. Breu

See the difference scientific optimization makes

Traditional Reading

✕Eyes constantly move (saccades)
✕40-50% time wasted on eye movement
✕Frequent regression (re-reading)
✕Typical: 200-250 WPM

Breu RSVP

✓Eyes stay perfectly still
✓100% time spent on comprehension
✓No regression needed
✓Typical: 400-600 WPM

Frequently Asked Questions

Everything you need to know about speed reading with Breu

Is RSVP reading really effective?

Yes! RSVP (Rapid Serial Visual Presentation) has been studied for over 40 years. Research consistently shows 2-3x speed improvements while maintaining comprehension. By eliminating eye movements (saccades), which consume 40-50% of reading time, RSVP allows your brain to focus entirely on processing words.

Will I lose comprehension at higher speeds?

Not if you increase speed gradually. Start at 250-300 WPM (slightly faster than normal) and work your way up over days or weeks. The app's adaptive timing adjusts for word difficulty, punctuation, and frequency to maintain natural comprehension. Most users find their sweet spot between 400-600 WPM.

Is my reading data private?

Absolutely. Breu processes everything locally on your device. We don't collect, store, or transmit any of your reading material. There are no analytics, no tracking, no servers. Your reading stays completely private.
