What should I look for in a reading app?

The formats it supports, the devices it runs on, where its books come from, the real cost per book, what happens when you cancel, and its App Store privacy label.

Are App Store privacy labels reliable?

They are written by the developer and Apple notes it has not verified them. They are still the quickest way to compare what apps say they collect.

Should I pay for a reading app?

Only after you know your habit. Start with free apps such as Libby and the free Kindle app, then pay for the plan that matches how many books you actually read or hear each month.

What is the most important thing when choosing a reading app?

Matching the app to the job. A library app, a store, a tracker and a recap tool all do different things, so decide what you need done first.

How do you choose the right reading app?

By the Best Reading Apps editors · Published 30 October 2026 · Checked 30 October 2026 · Desk research

Decide the job first, then check five things: which formats you read (print, ebook, audio), which devices you use, where your books come from (a store, a library or your shelf), what one book really costs on each plan, and what the App Store privacy label says. The app that fits all five for your main job is the right one, even if it is not the most popular.

Start with the job, not the app

Reading apps do very different jobs. A library app lends books, a store app sells them, a tracker logs what you read, and a recap tool helps you pick a story back up. Comparing a tracker with a store is like comparing a bookshop with a bookmark. Name the job first; our picks by job start there.

The 10-question checklist

1. What format is the book? Print, ebook or audiobook. Many apps cover only one or two.
2. Which devices will you use? Check iPhone, Android, tablet, e-reader and web. Some apps are iPhone only.
3. Where do your books come from? A store app only shows that store's books. A library app needs a card. A tracker works with any book.
4. What does one book cost? Divide the monthly price by the books you will really read or hear. Our price index does the sums for audiobook plans.
5. What happens if you cancel? Some plans let you keep books (Audible Premium, Libro.fm); others are rentals (Audible Standard, Kindle+, Everand).
6. Do credits expire? Libro.fm credits never expire; Audible Premium credits expire after 12 months; Magic Bookmark credits never expire.
7. What does the privacy label say? On the App Store, look for Data Used to Track You and Data Linked to You.
8. How many ratings sit behind the score? A 4.8 from 25 ratings tells you less than a 4.8 from a million.
9. Can you leave? Check whether you can export your data or files. DRM-free audiobooks and tracker exports make leaving easier.
10. Is there a free way to try it? Most store apps are free to install, libraries are free, and many subscriptions offer a trial.

How to read an App Store listing in two minutes

Header: the price, whether there are in-app purchases, and which devices it runs on.
Ratings: the average and the count. Treat a small count with caution.
In-App Purchases: the real subscription prices, which can differ from the maker's website. Audible's App Store prices, for example, differ from audible.com.
App Privacy: what is used to track you, linked to you, or not linked to you.
Version History: how recently it was updated and what changed.
Compatibility: the minimum iOS version. Thus Far, for example, needs iOS 26 or later; Magic Bookmark needs iOS 16.4 or later.

Privacy labels compared for popular reading apps

Labels are written by each developer and not verified by Apple, but they are the best quick comparison available. Here is what four popular reading apps list, from their App Store pages on 30 October 2026.

Common mistakes when picking a reading app

Paying for a subscription before checking the library. Libby and Hoopla are free with a card.
Buying into a store that does not fit your devices. Apple Books is for Apple devices; the Kindle app runs almost everywhere. See Apple Books vs Kindle.
Expecting one app to do everything. Most readers are happiest with two or three focused apps. See our starter kit for adult readers.
Trusting a high rating from a handful of reviews. Always read the count.
