Read full descriptionHide full description
BionicWords uses RSVP (Rapid Serial Visual Presentation) to display text one word at a time at a fixed focal point. Your eyes stay still. Words flow to you. No skimming, no re-reading, no losing your place. Every word lands exactly where your brain expects it. The secret is the Optimal Recognition Point. Each word is displayed with its natural focal letter highlighted โ the exact point where your eye locks when reading. Your brain recognises words faster, processes meaning quicker, and retains more. Start at 200 WPM. Work your way to 600. Push past 900 if you dare. Your reading speed is the only limit. HOW IT WORKS Paste any text, open a file, or load from your library Tap play โ words appear one at a time, centred on the focal point Your highlighted focal letter stays fixed, your eyes stay relaxed Adjust speed on the fly โ from a gentle 50 WPM to a blazing 1500 WPM WHAT YOU CAN READ Paste any text โ articles, study notes, emails, blog posts, book chapters. Import TXT files directly. Upgrade to Pro to import PDFs and EPUBs โ BionicWords intelligently strips out page numbers, headers, and formatting noise so you only see the words that matter. SMART READING Not all words are equal. BionicWords automatically pauses slightly longer at sentence endings, clause breaks, and complex words. The rhythm feels natural, not robotic โ even at high speeds. SPEED PRESETS FOR EVERY LEVEL Chill (150 WPM) โ relaxed, easy comprehension Normal (250 WPM) โ average adult reading speed Fast (400 WPM) โ comfortable push Rapid (600 WPM) โ serious readers Insane (900 WPM) โ speed reading territory Ludicrous (1200+ WPM) โ test your limits Or set any custom speed with the precision slider and fine-tune buttons โ adjustable in real-time, even mid-sentence. TRACK YOUR PROGRESS See your words read, time elapsed, and actual average WPM after every session. Upgrade to Pro for reading streaks, all-time stats, weekly charts, and a full reading history so you can pick up exactly where you left off. DISTRACTION-FREE DESIGN Pure black background. White text. Red focal point. Nothing else. No banners, no pop-ups, no clutter. When you're reading, BionicWords disappears โ leaving only the words and your focus.

Verdict
The clearest difference is update cadence: BionicWords at every 2 days against Calnote's every 6 days. BionicWords also leads on device support (3 vs 1) and iOS requirement (13.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.
