Read faster with less distraction. Rapid Reader helps you train focus and reading speed using RSVP (Rapid Serial Visual Presentation), where words appear one at a time at a fixed point on screen. Instead of constant eye-scanning and losing your place, your gaze stays anchored so reading feels smoother, calmer, and more controlled. Why people use Rapid Reader • Train to read faster while staying focused • Reduce losing your place while reading • Build a daily reading habit in just a few minutes • Practice with books, articles, and study content What makes it different • Fixed focus point with highlighted fixation letter • Adjustable speed (200–500+ WPM) • Custom fixation color and font size • Clean, minimal interface designed for deep focus • Dark mode for comfortable sessions Rapid Reader doesn’t force you to rush. It removes friction so you can read with better rhythm, attention, and consistency.

Verdict
The clearest difference is update cadence: Rapid Reader at every 2 weeks against Chronograph's every 16 months. Chronograph's advantage is iOS requirement (11.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
