A speed-reading app built on RSVP — one word at a time, at the pace you choose. Train your brain to read at 2–4× your normal speed.
One Word at a Time
Words flash at the focal point. Your eyes stay still — no scanning — so your brain processes text much faster.
Pink letter = your focal point
Adaptive Speed
Set your WPM then let Flicker auto-slow on complex words. It's like having a co-pilot for your brain.

About RSVP
Rapid Serial Visual Presentation flashes words one at a time at a fixed focal point. By eliminating saccadic eye movement, your brain processes text significantly faster. Flicker layers adaptive speed, smart punctuation pauses, bionic reading, and a focus system on top.
