Amazon Kindle: Reading App

Review by eFreeware

The most striking thing about Amazon Kindle is how long it has been doing this job. The app arrived on Android in June 2010 and has been updated as recently as October 2026, which tells you the reading experience has been refined over many years rather than launched and forgotten. It is free to install, sits in the Books & Reference category, and has been picked up more than 100 million times, with a 4.8 average across roughly 4.8 million ratings.

What that history translates into is a reading app rather than a storefront with a reader bolted on. The catalog is the headline: millions of books, plus magazines, newspapers, comics and manga, and the option to open a sample before deciding whether to buy on Amazon.com. If your reading life is already tied to a Kindle library, or you want one place to hold books, comics and periodicals together, this is the obvious starting point.

It is also the app for someone who reads in fragments. Because your position in a book, along with bookmarks, highlights and notes, syncs between devices, the same title follows you from a phone to a tablet without you having to remember where you stopped. That single behavior does more for the app's usefulness than any individual reading feature.

Samples, subscriptions and what fills the shelves

The feature the developer leads with is breadth of access, and it comes in three layers. The first is straightforward purchase: browse millions of Kindle titles, try any of them as a sample inside the app, then buy through Amazon.com. Samples are the part I would lean on most, since they let you judge a book's tone and pacing before spending anything.

The second layer is Kindle Unlimited. A membership opens up over a million titles, plus thousands of audiobooks and current magazines, with no limits on reading or listening. The third is for Prime members, who get thousands of books, magazines and comics included with their membership. Between them, these two programs are the reason the app can feel like a library rather than a shop, though each depends on holding the relevant membership.

The catalog is not limited to novels. Romance, science fiction, children's books, self-help, religion and nonfiction all appear in the mix, alongside Amazon Charts best sellers and new releases. Comics and manga benefit from high-definition color images you can zoom into, which matters more on a tablet than a phone. Books with Audible narration sit in the same catalog.

Making the page look the way you want

Reading comfort is handled through the Aa menu inside a book, and the range of adjustments is wider than you might expect from a phone app. Text size, font type, margins, alignment and orientation are all yours to set, and you can choose between turning pages one at a time or scrolling continuously. Brightness and background colors are adjustable too, which is what makes long sessions at night tolerable.

The supporting tools are aimed at the friction that interrupts reading. Tap and hold a word for the built-in dictionary, or follow links out to Google and Wikipedia when a name or place needs more than a definition. X-Ray and instant translations cover the cases where you have lost track of a character or hit a phrase in another language, and search within a book lets you find a passage you half remember.

Progress tracking is more specific than a percentage bar. Progress markers show your position in a book, page numbers for most popular titles, and time left in the chapter or the whole book. For anyone who plans reading around a commute or a lunch break, that estimate is the number worth glancing at.

Notes and marks are collected rather than scattered. Bookmarks flag places to return to, highlights and notes can be made as you go, and My Notebook gathers all of your notes in one view. Page Flip lets you skim ahead or pull back to a bird's-eye view of the book, and your place is preserved while you move around. When reading is not possible, you can switch from the text to the Audible narration inside the same app.

What the app asks of you

The install itself costs nothing. It contains advertising and offers in-app purchases, and the reading you do beyond samples depends on buying titles, holding a Kindle Unlimited membership, or having Prime. Those are three different routes into the same catalog, and which one makes sense depends on how much you read and whether you already pay for Prime.

Samples lead to purchases on Amazon.com, Prime inclusion is tied to a Prime membership, and your library, notes and reading position live in that account rather than on the device.

The content rating is Teen, which reflects the catalog rather than the app's own behavior. Because the shelves span children's books through to nonfiction and genre fiction, the range of material available is broad, and the developer points readers to Amazon's Conditions of Use and Privacy Notice for the terms that govern the app.

Getting the most from it day to day

The habit I would build first is sampling. Before committing to a book, open the sample and read it in the conditions you actually read in, whether that is a bright room or a dark one. Adjust the Aa settings during that sample rather than after you have started, since font, margin and background choices change how much text fits on a screen and how quickly a page turns.

Second, treat the progress display as a planning tool rather than a scoreboard. Knowing the time left in a chapter is more useful than knowing the percentage of the book, especially if you read in short windows and dislike stopping mid-scene. Page Flip pairs well with this: skim to see how much is left in a section, then return to your place.

Third, lean on notes if you read anything you intend to use later. Highlights and My Notebook turn a book into something you can revisit without flipping back through pages, and because all of it syncs, the notes are there whichever device you pick up. The same applies to bookmarks, which are worth setting at any passage you expect to want again.

Decide early which access route fits you. If you read a book or two a month, samples plus individual purchases keep things simple. Prime members should check what is already included before buying anything, because thousands of books, magazines and comics come with that membership.

Finally, the recent addition worth knowing about is a Home screen widget for your last book read. Adding it means the title you are partway through is one tap away, which suits anyone who reads in odd moments and would rather not hunt through a library to resume.

Where the free part ends

The trade-off with Kindle is that convenience comes with a store attached. The app carries ads and in-app purchases, and while samples and Prime inclusions soften that, the deeper you read, the more the catalog points back to buying or subscribing. That is a reasonable model for a reading app tied to a retailer, but it is worth going in with your eyes open rather than expecting an open-ended free reader.

The strongest features are the ones that assume you are already inside the ecosystem. For a reader with an established Kindle library that is an advantage.

None of this undermines what the app does well. The reading tools are thorough, the catalog is enormous, and the syncing behavior is the sort of thing you notice most when it is absent. The question is less whether the app is capable and more whether its commercial shape matches how you read.

A reading app for people with a Kindle habit

I would point this app at anyone who already reads on a Kindle or buys books from Amazon, and at anyone who wants a single place for books, comics, magazines and manga on a phone or tablet. The customization, the dictionary and lookup tools, the progress estimates and the notes all support long-form reading rather than quick browsing, and the cross-device syncing is what makes it feel like one library instead of several.

If you read a great deal and want listening included, Kindle Unlimited is the route the app is shaped around; if you are a Prime member, check your included titles before paying for anything. If you read occasionally, samples and individual purchases work perfectly well. Either way, install it expecting a reading experience tied to Amazon's catalog and account, because that is both its strength and its boundary.

What's new

You can now add a Kindle 'Last Book Read' widget to your Android Home screen for quick access to your most recent read on Kindle. Long press the "Kindle" app icon and select "Widgets" from the popup menu, long press the widget and drag it to the desired position on your Home screen.
