IO reader vs Apple Books
Apple Books ships on every iPhone and reads like a traditional book; IO reader takes the same public-domain text and turns it into something closer to how you already scroll — Reels and sentence cards, with a bench of AI reading companions standing next to the page.
| IO reader | Apple Books | |
|---|---|---|
| Reading modes | Vertical Reels or one-sentence cards | Traditional page-by-page reader |
| AI | 12 reading companions prompted to never summarize, alongside the text | None |
| Library | Thousands of public-domain classics free to read | A classics section in the Books Store, plus a paid general catalog |
| Imports | DRM-free EPUB files and web articles | Imports EPUB files you already own |
| Offline reading | Yes, once downloaded | Yes, for downloaded books |
| Price | Free tier; IO+ $2.99/mo or $24.99/yr | Free app; books in the store are priced individually |
| Platforms | iPhone and Android | iPhone, iPad, Mac |
| Lock-in | Public-domain text you can read anywhere | Built into Apple's ecosystem; no Android version |
Best for IO reader
- You want the classics as Reels or sentence cards, not a plain page.
- You're on Android, where Apple Books doesn't exist at all.
- You want twelve AI reading companions adding context as you read, not a silent reader.
Best for Apple Books
- You're on iPhone or Mac only and want a reader that's already installed, no download.
- You buy books through Apple's store and want purchases in one place.
- You want the simplest possible page-turning reader with zero AI layer.
Is IO reader just a copy of Apple Books?
No — the reading model is different. Apple Books is a page-by-page reader with no AI layer. IO reader restructures the same public-domain text into vertical Reels or single-sentence cards, and pairs it with twelve reading companions that add context, history, and craft notes as you go.
Does Apple Books work on Android?
It doesn't — Apple Books is limited to iPhone, iPad, and Mac. IO reader is built for both iPhone and Android, so the format works the same either way.
When does Apple Books make more sense?
If you already own books through Apple's store, or you want a plain, distraction-free page reader that's already installed on your phone, Apple Books is the simpler choice. IO reader is for readers who want the classics presented differently — and want an AI layer that adds perspective without doing the reading for you.
