A speed reading app tries to help you read faster, usually by flashing words one at a time in one spot, guiding your eyes with a highlight or giving you drills. The research is clear that much faster reading usually trades away some understanding, so the useful apps help you read steadily and check comprehension. Ten apps follow, in no particular order.
Most speed reading apps use one of three ideas. Some show one word at a time in a fixed spot, a method the listings call RSVP, or rapid serial visual presentation. Some move a highlighter along normal text to set your pace. Others give you exercises for focus and eye movement.
The ten apps below are listed alphabetically and in no particular order, and each description comes from the app's own App Store listing, read this week. Speed claims are hard to check, so I've kept the descriptions to what each app says it does, not how fast it says you'll read. If you read mostly for exams, my guide to finding free exam study materials pairs well with whichever app you choose.
Speed reading apps at a glance
I checked the free plan column on each app's own App Store listing, as of Oct 2026. Yes means the listing names a free app, a free version, a free tier or free content. Trial only means a time-limited trial. Not stated means the listing I read named neither, even where there's a download button, so check the app's own page before you subscribe.

Ten speed reading apps worth a look
Celeris
Best for: Curious readers who want to try one-word-at-a-time reading free first, with a small library of books before any upgrade.
FocalRead
Best for: Students with a pile of PDFs, ebooks and web articles who want one library that can play any of them word by word.
Outread
Best for: Anyone who finds word flashing tiring and would rather follow a highlighter along the page or keep text centred.
Reading Trainer
Best for: People who want practice exercises for reading speed and comprehension, rather than a reader for their own books.
Redd
Best for: Commuters who've found standard word-flashing apps hard on the eyes and want a different take on rapid serial visual presentation.
Reed
Best for: Book lovers who want their own EPUBs, PDFs and text files shown one word at a time with the key letter highlighted.
Speble
Best for: Tinkerers who like options, with a flowing highlight mode and other modes that pace your eyes at the speed you set.
Spreeder
Best for: Learners who want guided courses that teach speed reading step by step, not just a fast reader.
TurboRead
Best for: Students who want an AI-made quiz after each passage, so faster reading doesn't quietly wipe out their understanding.
Wordex
Best for: Slow-and-steady types who'd rather build a daily habit with short sessions than chase big speed claims, with regular reading free.

What the research says about reading faster
A 2016 review in Psychological Science in the Public Interest looked at what scientists know about reading and what it means for speed reading apps. It found a trade-off between speed and accuracy, and said it's unlikely that readers can double or triple their speed, from around 250 to 500 to 750 words per minute, while still understanding the text.
That doesn't make these apps useless. It means the honest gains come from better focus, less re-reading and knowing when to skim, not from a dramatic jump in words per minute. Treat any promise of tripled speed with care.
When fast reading helps and when it hurts
- Helps: skimming news, emails, light fiction or a chapter you've already studied once.
- Hurts: textbooks, contracts, maths and anything you'll be tested on in detail.
- Depends: research papers, where skimming the abstract fast and reading the method slowly works well.
How to test any app in a week
- Time yourself reading two pages of a normal book, then write three things you remember.
- Use the app for ten minutes a day on similar text.
- On day seven, repeat the timed reading and the three-point recall.
- Keep the app only if your speed rose and your recall held up.

My plain advice on speed reading apps
Pick an app that helps you focus and stop re-reading, and always check your understanding as you go. If your recall drops, slow down: reading something once at a steady pace beats skimming it three times.
For study material, active techniques usually beat raw speed. My guide to ChatGPT prompts that help students study effectively has ways to quiz yourself on what you've read.
Frequently asked questions
Do speed reading apps work?
They can help with focus and skimming, but a 2016 research review found that much faster reading usually trades away some understanding.

RSVP, or rapid serial visual presentation, shows text one word at a time in one spot so your eyes don't move across lines.
Are there free speed reading apps?
Yes, several apps here name free reading, a free starter level or free imports on their listing, so check the free plan column.
Can you double your reading speed?
The 2016 review said it's unlikely you can double or triple your speed while still understanding the text.
Is speed reading good for studying?
