I Tried Every Speed Reading App So You Don't Have To
I spent three weeks using every major speed reading app I could find. Not a quick-install-and-screenshot review — actual daily use, working through each app's training program, reading my normal work material with each tool, and tracking my results.
Here's what I found, including what each app does well and where the gaps are. I work at Lumen, so take my perspective with appropriate skepticism — but I'll do my best to be fair. You can judge whether I succeeded.
The Landscape
The "speed reading app" category actually contains several very different products trying to solve different problems. Grouping them together is a bit like comparing a gym membership, a nutrition app, and a protein bar — they're all "fitness" products but they work differently and serve different needs.
Here's how I'd categorize the major players:
RSVP-only tools — present text one word at a time at adjustable speeds. Spreeder is the most well-known.
Content summarizers — condense books and articles into shorter formats. Blinkist leads this category.
Text-to-speech tools — read content aloud so you can "read" while doing other things. Speechify is the dominant player.
Comprehensive training apps — teach multiple reading techniques with structured practice. This is where Lumen sits.
These categories matter because comparing a summarizer to a training app is comparing different value propositions entirely.
Spreeder: The OG RSVP Tool
What it is: A web-based and mobile tool that displays text one word at a time (RSVP) at your chosen speed. Paste in text or upload a document, set your WPM, and go.
What it does well: Spreeder is simple and focused. If you want pure RSVP with minimal friction, it delivers. The interface is clean, there's no bloat, and it works exactly as advertised. The free version is genuinely usable — you can paste text and start reading immediately. For people who just want a straightforward RSVP reader, it's hard to beat on simplicity.
The Chrome extension is also a nice touch — highlight text on any webpage and read it in RSVP mode without leaving the page.
Where it falls short: Spreeder is a tool, not a training program. It gives you one technique (RSVP) and lets you adjust the speed. There's no comprehension measurement, no adaptive difficulty, no progression system, and no guidance on when RSVP is the right approach versus when you'd be better off reading normally.
The fundamental problem: RSVP at high speeds without comprehension tracking lets you feel fast without confirming you're actually absorbing anything. Spreeder Pro adds some features, but the core experience is still "words go fast" without feedback on whether your brain kept up.
Best for: People who already know they like RSVP and want a clean, minimal tool for it. Not ideal if you're trying to build broader reading skills.
Rating: 3/5 — Does one thing, does it cleanly, but one technique isn't a training program.
Blinkist: Reading Replacement, Not Reading Improvement
What it is: A library of 15-minute summaries ("Blinks") of nonfiction books, available as text or audio.
What it does well: Blinkist is excellent at what it actually is — a content curation and summarization service. The summaries are well-written, the book selection is strong (especially for business, psychology, and self-improvement), and the audio versions are polished. If you want the key ideas from 50 books this year without reading 50 books, Blinkist delivers real value.
The reading experience itself is pleasant. The app is well-designed, the content is organized thoughtfully, and the "daily pick" feature surfaces books you might not have found on your own.
Where it falls short: Blinkist doesn't teach you to read faster. It gives you less to read. That's a fundamentally different proposition, and it's important to be clear about it.
A 15-minute summary of a 300-page book is not the same as reading the book faster. You're getting the author's conclusions without the reasoning, the examples, the nuance, and the arguments that make those conclusions meaningful. For some books, that's fine — not every book deserves six hours of your time. For others, the summary strips out exactly the parts that matter.
Blinkist also doesn't help with the reading you have to do in full — reports, research papers, technical documentation, long-form journalism. It's a complement to reading, not an improvement in reading ability.
Best for: Busy people who want broad exposure to nonfiction ideas. Not a speed reading solution — more of a reading triage tool.
Rating: 4/5 — for what it is. But it's not a speed reading app, and rating it as one would be unfair to both Blinkist and the category.
Speechify: Listen, Don't Read
What it is: A text-to-speech app that reads content aloud using high-quality AI voices. Works with documents, web pages, PDFs, and ebooks.
What it does well: Speechify has the best text-to-speech engine in the consumer space. The AI voices are remarkably natural — a genuine step up from the robotic TTS of a few years ago. The app handles a wide range of formats (PDFs, web articles, Google Docs, physical books via OCR), and the speed controls are smooth. You can listen at 2–3x speed and still understand the content.
The use case is compelling: "read" while commuting, exercising, or doing chores. For people who struggle with traditional reading due to dyslexia or visual fatigue, Speechify is genuinely transformative.
Where it falls short: Listening isn't reading. This isn't a value judgment — it's a cognitive science observation. Reading and listening engage different processing pathways. Research by Daniel and Woody (2010) found that reading generally produces better comprehension and recall than listening for complex material, particularly when the content requires careful analysis or when you need to reference specific passages.
Speechify also doesn't build reading skills. You can become a better listener with practice, but the skills don't transfer to faster visual reading. If your goal is to improve how you read text on a screen or page, Speechify doesn't address that.
The pricing is also aggressive — the premium tier is significantly more expensive than most reading tools, and many features are locked behind it.
Best for: Audiobook enthusiasts, commuters, people with visual processing challenges, and anyone who needs to consume text-heavy content hands-free. Not a substitute for learning to read faster.
Rating: 3.5/5 — excellent at audio conversion, but solving a different problem than speed reading training.
Lumen: Full Disclosure, This Is Us
What it is: A speed reading training app that teaches seven evidence-backed techniques (RSVP, Eye Movement Training, Meta-Guiding, Chunking, Skimming/Scanning, SQ3R, Subvocalization Optimization) and tracks performance using Effective Reading Rate (ERR = WPM × Comprehension %).
What it does well: I'm biased, so here's what I'd point to if I were trying to be objective.
Lumen is the only app in this comparison that treats speed reading as a skill set rather than a single trick. The seven techniques aren't gimmicks — each has research behind it (Rayner et al. 2016 covers the evidence for most of them), and the app teaches you when to apply each one. RSVP for email newsletters, SQ3R for research papers, skimming for daily news — matching technique to context is where the real efficiency gains come from.
The ERR metric is, I believe, a meaningful differentiator. Tracking comprehension alongside speed prevents the "going fast but retaining nothing" trap that pure WPM tracking creates. The adaptive training adjusts difficulty based on your ERR, not just your speed, so it pushes you to get genuinely faster rather than just feeling faster.
Where it falls short: Lumen is more demanding than the alternatives. There's a learning curve — seven techniques plus comprehension testing means more investment upfront than pasting text into Spreeder and hitting play. If you want a tool you can use in 30 seconds with zero training, Lumen isn't that.
The content library is also younger than Blinkist's or Speechify's massive catalogs. For readers who want a built-in library of material, the selection is growing but not yet at the scale of apps that have been in market for years.
And the honest truth: structured reading practice requires consistency. Lumen's training works, but it works over weeks and months, not overnight. Anyone promising overnight results is lying — but the time investment is still a real barrier for people with packed schedules.
Best for: Readers who want to systematically improve their actual reading ability — not just consume content differently — and are willing to invest 15–20 minutes a day in deliberate practice.
Rating: I'll let you decide this one. Rating your own product is a conflict of interest I'd rather not pretend to resolve.

What I'd Actually Recommend
If you want broad exposure to book ideas and don't care about reading speed: Blinkist.
If you want to "read" while doing other things: Speechify.
If you want a quick, simple RSVP reader with no learning curve: Spreeder.
If you want to actually get better at reading — faster comprehension, better retention, skills that transfer to everything you read: that's what we built Lumen to do. It's more work upfront, and I won't pretend otherwise. But the skills compound in a way that tools and content libraries don't.
