Whether you're a student, professional, or avid reader, FlowSpeedReader trains your brain to process words at incredible speeds — all while maintaining comprehension. HOW IT WORKS RSVP displays one word (or a group of words) at a time in a fixed position, eliminating the eye movements (saccades) that waste up to 30% of traditional reading time.
