In my hunt for the best e-readers, I’ve been determined to find a great alternative to a Kindle or a Kobo. Don’t get me wrong, I love both of these e-readers and generally think they are the best e-readers you can buy, but I know there’s a hunger for variety in the e-reader community beyond the big two. I’ve tried Barnes & Noble’s Nook, Remarkable e-ink tablets, and Boox e-readers, but none of them have impressed me. But the Durobo Krono caught my eye at CES 2026.

I’ve often called an e-reader a library in your pocket, and the Durobo Krono is more than that. It’s a library, bookstore, notebook, and MP3 player all in one. But that’s a lot of promise in a palm-sized device. Luckily, it totally nails it. Here’s what you need to know about the Durobo Krono and why I named it the best open-source Android e-reader.

I find myself in a unique conundrum as an e-reader tester: I have collections of books across many different e-reader platforms. While I could just get used to cycling through different e-readers regularly, that’s a lot to keep track of. The dream is to have them all on one device, and the Durobo Krono is that dream realized.

Running Android 15, the Google Play Store comes preinstalled on the Krono, so any app available in the store is available on the e-ink tablet. Suddenly, all the apps I use regularly from Audible, Kindle, Kobo Books, Libby, and Libro.fm are now on my Durobo Krono.

The apps appear on a separate page from Krono’s built-in library, so you will need to navigate between them. A small price to pay for the convenience of accessing them from one device.

Technically, you could get this convenience from a tablet, too. Except an iPad doesn’t have the matte, easy-on-the-eyes e-ink display that the Krono does.

Since it’s an Android device, Apple apps (like Apple Music and Apple Books) aren’t available, so as an Apple Music listener, I couldn’t use the device as a music player.

It’s fast — until it’s not

In my testing, I find open Android e-readers to be too slow, especially compared to Kindles and Kobos, which are zippy e-readers. The Boox Go and Boox Palma 2, similar devices to the Durobo Krono, have both had disappointing performance, even right out of the box. Yet, the Durobo Krono is brilliantly speedy. Even when moving between different books on different apps, I was impressed by how quickly it sped through them.

Its speed is conditional. Too many apps, or more demanding apps, will slow down the device. After a week of use, I added the Substack app to the Krono, which was too demanding for it. Even when I wasn’t using the app, it slowed down the whole device. Once I deleted the app, it sped back up.

Other demanding apps I found were audiobook players like Audible. I especially noticed this when listening to an audiobook while reading an e-book on a separate app. It’s disappointing that two apps geared toward readers slowed down an e-reader device. For the best performance on the Krono, use one app at a time and avoid high-demanding apps.

A perfect palm-sized e-reader

The Durobo Krono has a 6.13-inch screen, slightly bigger than the basic Kindle‘s, but the entire device is narrower than the Kindle. It’s about the same size as my hand and weighs 6.1 ounces. The small size makes it comfortable to hold for hours at a time — especially if you add a PopSockets grip on the back as I did. But that doesn’t make the screen size feel cramped either.

It needs better battery life

When you’re used to the months-long battery life of a Kindle, it’s a hard adjustment to go to an e-reader with significantly less. With a couple of hours of use per day, the Durobo Krono e-readers have about one week of battery life. Compared to a smartphone or tablet, that’s pretty good, but when you’re coming from a Kindle or even a Kobo, the Krono e-reader’s battery life feels too short.

The features on the Krono Durobo are extensive. It has a smart dial on the side that refreshes the screen, starts recording, and scrolls on the device. It has a built-in AI called Spark, which captures voice recordings and produces transcripts and summaries. It’s a lot more than just a standard e-reader, but in the months of use, I never used the Spark AI. The Smart Dial is a fantastic addition for smooth scrolling.

The Durobo Krono is the best open Android e-reader. If you’re exploring the world of the Boox Palma or the Remarkable Move, the Krono is my preferred pick for its fast processing and support for third-party apps. In a perfect, palm-sized package, it provides access to all your digital libraries. It’s more expensive than other e-readers, but for its extra benefits, it’s worth the extra price.
