The Best Way to Read Books on iPhone

A lot of people arrive here searching for a speed reading app for iPhone, and what they actually want is to finish the books on their phone and keep what they read. Velo is built for that, not for a pace claim: a premium reader for the EPUBs and PDFs you own, with a Focus Mode that holds your attention inside them.

It takes both halves. A reader good enough to stay in, and something that keeps your eyes on the text on the one screen designed to pull them away.

It reads like the book

Bring any EPUB or PDF you own. Velo honours the book's own typography, or hands you Georgia, Iowan Old Style, a system serif or sans, with text size, line spacing and brightness under your control. Figures, footnotes and chapter structure render as the publisher built them, with a real table of contents. PDFs are rebuilt on-device into reflowing books: chapters detected, running headers stripped, footnotes linked. Your library lives on the phone and reads fully offline — the book is never uploaded.

Focus Mode, for the screen built to interrupt you

The iPhone is where reading mechanics are worst: short lines, constant return sweeps, and a device designed to pull you away. Focus Mode (RSVP) removes the mechanical overhead entirely — one word at a time on a fixed focal point. Nothing to scan, no line to re-find, nowhere for your eyes to wander.

The mechanics, as specs: 50 to 1,000 words per minute, each word aligned to its optimal recognition point, timing that adapts to punctuation and complexity. The low end of that range matters as much as the high end — one word at a time at 150 WPM on a hard paragraph is the mode doing its best work.

That's a deliberate decision. An app that locks its core feature behind a subscription is selling you a demo. In Velo, the free tier includes every reading mode, EPUB and PDF import for up to 3 books, reading stats, and the on-device intelligence dashboard — plus a built-in library of classics to read immediately. Pro ($69.99/year or $8.99/month, 7-day trial) removes the 3-book cap and adds cloud sync and Listen, the read-aloud mode with word-by-word tracking.

The part that makes it a reader, not a gimmick

A bare word stream loses things — readers naturally re-read about 10–15% of the time, and blocking that hurts comprehension of difficult passages. Velo is built around the way back:

• Reader mode — a full typeset page with your position highlighted. Re-read, scan ahead, let your eyes roam.
• Scrub — drag backwards through the stream with momentum to catch what you half-heard in your head.
• One position, three modes — switching lands in under 100 ms, mid-sentence, and nothing is lost. This is the difference between a party trick and a reader you can trust with a whole book.

It reads what you already own

Velo isn't a bookstore. It reads DRM-free EPUB and PDF files — plus TXT, Markdown, and web articles shared from Safari — imported through the iOS Share Sheet. Kindle and Apple Books purchases are DRM-locked to those stores and no third-party app can open them, Velo included.

How to use it without fooling yourself

First, the claim nobody else will make plainly: the research does not support reading dramatically faster with full comprehension. Decades of work — most prominently Keith Rayner's reviews of the reading literature — found that large pace gains essentially always cost comprehension, and Velo does not claim otherwise. The dial is there to be turned down as often as up.

So: start near your normal pace, around 250–300 WPM. Raise it only on easy material. Drop to the page view the moment you feel lost — the instinct to re-read is correct, and suppressing it is what wrecks comprehension. Used that way, the technique holds up. We've written the full evidence-based case in what is RSVP reading? and the deeper trade-offs in pace vs. comprehension.
