The best speed reading app depends on where you read. For speed reading any web page in the browser, SwiftRead is the most complete extension. For a native iPhone and Mac reader, Outread is the most polished. For a structured course, Spreeder. For listening instead of reading, Speechify; for a read-it-later workflow with highlights, Readwise Reader. For free drills and a paced reader with no account, Tachi, which is our product. None of them will multiply your reading speed with full comprehension, and the honest ones do not need to.
We checked every product below on its own website and app-store pages on 13 November 2026. Prices are in US dollars, change often and can differ by country and platform.
What a speed reading app can and cannot do
Apps use a few methods: RSVP (one word or phrase at a time in one spot), a moving highlight over the full page, bolded word-beginnings, colour gradients that guide the eye between lines, and text-to-speech. Research reviewed by Rayner and colleagues (2016) found that comprehension falls when reading is pushed well beyond a person's normal rate, and that eye movements take only about a tenth of reading time. A 2024 experiment found that bionic-style bolding did not change reading time (Snell, 2024). So judge an app by whether it helps you focus, keep a steady pace and get through a backlog, not by its WPM claims.
If an app promises to triple your speed, read that as "helps you skim". A good app lets you choose a pace at which you can still summarise what you read.

The apps, one by one
SwiftRead: best for reading anything in the browser
SwiftRead opens web pages, PDFs, local files, selected text and books in Kindle Cloud Reader and Libby in its own reader, with three modes: Focus (a few words at a time in one spot), Flow (a highlight moving through the full page) and Spotlight. It also reads aloud with highlighted words, and syncs a library across its web, iOS and Android apps. The Chrome Web Store listing says all features are free, with daily allowances on text-to-speech and premium pages. PRO removes the limits; on the US App Store it is $19.99 a month, $44.99 a quarter or $119.99 a year. Its strength over Tachi is obvious: it works on any page you are already looking at.
Outread: best native app for iPhone, iPad and Mac
Outread has two reading modes, Guide (a highlight that moves along the page) and Flash (one phrase at a time), plus eye and memory exercises, speed and comprehension tests, text-to-speech, offline reading and AI summaries on supported devices. Your own ePub, PDF and Word files, speeds up to 1,500 WPM and more need Outread+. App Store prices range from a $2.99 weekly plan to a $119.99 lifetime licence (US store), and the listing showed a 4.7 rating from about 1,400 ratings on 13 November 2026. It is Apple-only.
Spreeder: best for a structured course
Spreeder, by eReflect, combines an RSVP reader with four modes, a regular e-reader, guided courses, daily exercises, AI summaries and a cloud library that imports many file formats. It runs on the web, desktop and mobile, with browser extensions for saving articles. The website sells lifetime access but did not display a price when we checked; the iOS app is free with a $6.99 VIP in-app purchase. Its site claims a 3x faster reading pace on average; we found no independent evidence for that figure.
AccelaReader: best free RSVP for a quick try
AccelaReader, from the course company Iris Reading, is a single web page: paste text, set a WPM and chunk size, press play. It can pause at sentence ends and skip stop-words. There is no library or file import, which also makes it the fastest way to see what RSVP feels like.
Bionic Reading: a typographic style, not a speed tool
Bionic Reading converts files, text and websites so that the start of each word is bold, with apps on most platforms, a Word add-in and an API. There is a free version and paid Premium tiers. The App Store listing had a 2.4 rating from 156 ratings on 13 November 2026. Tests so far, including Snell (2024), found no speed benefit; use it if you like the look. See RSVP vs bionic reading.
BeeLine Reader: best for losing your place between lines
BeeLine tints each line of text with a colour gradient that runs into the next line, so the eye finds the start of the following line more easily. It works as a browser extension on most web pages and text-based PDFs. The free mode works on a list of favourite sites you choose; BeeLine Pro is $1.99 a month according to its Chrome Web Store listing, and the Safari extension on iPhone and iPad is free.
Speechify: the listening alternative
Speechify reads documents, web pages and scanned pages aloud with highlighted words. The free plan offers basic voices at up to 1.5x speed; Premium, at $29 a month or $139 a year on its pricing page, adds more natural voices, faster playback and AI summaries (App Store prices differ). In one study, adults understood a non-fiction text about equally well by listening or reading (Rogowsky et al., 2016), so listening is a real alternative when your eyes are busy. It is not good for skimming.
Readwise Reader: the reading-workflow alternative
Reader is not a speed reader. It collects articles, PDFs, EPUBs, newsletters and feeds in one place, with highlighting, notes and text-to-speech, on every major platform. After a 30-day trial it is part of a Readwise subscription: $9.99 a month billed annually or $12.99 billed monthly. If your problem is a scattered backlog rather than slow reading, start here.
Tachi: free drills and a paced reader, no account
Tachi runs in the browser. It has nine short eye and perception drills (Schulte table, tachistoscope, peripheral letters and others), a reader with six modes from RSVP to a full-page pacer at 100 to 1,000 WPM, and a reading speed test. You can paste text or import PDF, EPUB and TXT files, which are converted in the browser and not uploaded. The interface and practice material come in 29 languages. It is free, with no account and no subscription.
Where it falls short: there is no browser extension, so it cannot read a web page in place; it has no text-to-speech; progress does not sync between devices; and it needs a connection to load. The iOS app is planned but not yet released. The method behind it is explained in How Tachi works.
How to choose a speed reading app
- Start from where your reading lives. Mostly web pages: a browser extension (SwiftRead, BeeLine). Mostly ebooks and PDFs on an iPhone: Outread. Files on any device without installing anything: Tachi.
- Decide whether you want to read or listen. If your eyes are the problem, a text-to-speech app may serve you better than any speed reader.
- Test before paying. Every product here has a free tier or trial. Read the same 500-word passage in each at your normal speed and write a two-sentence summary afterwards.
- Ignore the WPM ceiling. A slider that goes to 1,500 WPM is not a reason to choose an app. Pick the one in which you can follow the text comfortably.
- Check the subscription terms. Weekly plans add up; a lifetime licence or a free tool may suit occasional use.
For background, read what RSVP reading is, speed reading on your phone and the wider speed reading guide. If you plan to read documents, how to speed read a PDF walks through the workflow.
How we compared
On 13 November 2026 we read each product's official website and its US App Store or Chrome Web Store listing, and recorded platforms, the free and paid model, prices where shown, and what the product actually does. We did not run timed trials or score the apps, and we report no ratings or user numbers except the two we read that day. We dropped Readsy, an older free RSVP web tool, because its domain no longer hosts the product. Claims about reading speed made by any of these companies, including any made by us, are not independently verified unless a study is cited.
Disclosure: Tachi is our product. We have tried to describe it with the same detail and the same limits as the others. If you spot something out of date, the prices and features above are the first things to change.
Frequently asked questions
What is the best free speed reading app?
For reading web pages, SwiftRead's free tier covers all three reading modes with daily limits on text-to-speech and some sources. AccelaReader is a free one-page RSVP tool. Tachi is free without limits or an account and adds drills and a speed test, but it reads pasted text and files rather than web pages in place.
Do speed reading apps actually work?
They work as pacers: they hold you at a chosen speed and reduce drifting, which helps with a backlog. Research has not shown that any app lets people read several times faster with full comprehension. Word-at-a-time display matches normal comprehension at ordinary speeds and loses it as the rate rises.
Which speed reading app works on any website?
Browser extensions do. SwiftRead opens the page you are on in its own reader with RSVP, highlight and text-to-speech modes. BeeLine Reader and Bionic Reading restyle the page in place with colour gradients or bold word-starts. Spreeder's extension saves articles to its library. Tachi has no extension; you paste the text or import a file.
Is there a speed reading app for Android?
Yes. SwiftRead, Spreeder, Bionic Reading and Speechify all list Android apps, and BeeLine offers an Android app called Readme!. Outread is Apple-only. Tachi runs in any mobile browser, including on Android, without installing anything.
Should I pay for a speed reading app?
Only after trying the free tier on your own reading. Pay if a feature you will use every day is behind the paywall, such as unlimited text-to-speech, Kindle support or file import. Do not pay for a promise of a specific speed gain, which no app has demonstrated in independent research.
