DuRoBo Krono — A Pocket E-ink Reader You Flip With a Smart Dial
Tapping the screen every time you want to turn a page on an e-reader gets kind of annoying, right? The DuRoBo Krono puts a physical dial (the smart dial) on the back, so you can hold it in your hand and spin it with your thumb to scroll and flip pages. The pocket-sized body plus that one dial immediately caught my eye.

🔍 Why I'm Interested
A smart dial that keeps your hand in place
What drew me in most is the knurled dial on the back. While holding the reader, spinning the dial with your thumb scrolls through books or web pages and turns them. No need to keep tapping the screen — one-handed reading looks a lot more comfortable. I've also heard that dial-based page turns have gotten smoother even in third-party apps like Kindle recently.
A 6.13-inch screen that fits in your pocket
At 6.13 inches with a slim form factor, it's a size that fits right in your pocket. The 300ppi Carta 1200 E-ink keeps text crisp, and the glare-free e-ink display is easy on the eyes even over long reading sessions. A great size to carry around and read in spare moments.
An Android hub, not just an e-reader
It's not just an e-reader — it runs full Android 15 underneath. You can install whatever apps you want, and there's an AI note feature called "Spark" that automatically transcribes voice memos into text. It's positioned as a "focus hub" that bundles reading, idea capture, and audio playback into one device.
A monochrome screen that cuts down on distraction
Unlike a color smartphone, the monochrome E-ink display means fewer temptations from notifications and video. It's a device built around "reading and focus," which suits anyone who wants to put their phone down and immerse themselves in reading and note-taking.
🤔 What Gives Me Pause
First-generation crowdfunding polish
This is DuRoBo's first product, and it started out on Kickstarter. The idea is great, but early reviews point out that third-party app compatibility and software polish still need work. It's worth factoring in the rough edges typical of a first generation.
E-ink's usual ghosting and lag
Even with Android running underneath, E-ink still isn't as fast as an LCD. There can be ghosting or sluggish response during scrolling and transitions, so if you're expecting it to feel like a smartphone, you might be disappointed.
No official domestic sales channel
Right now it's mainly sold through Amazon US/UK and the brand's own store. There's no clear official sales or A/S channel in Korea, so you'll need to factor in importing it yourself and check pricing, shipping, and warranty terms.

🛒 Before You Buy
✅ Recommended for
- Anyone looking for a minimal E-ink reader they can comfortably flip through one-handed
- Anyone who enjoys physical controls like dials or knobs
- Anyone who wants a monochrome screen to cut distraction and focus on reading and note-taking
❌ Not recommended for
- Anyone expecting smartphone-level speed or color
- Anyone who only wants to buy fully polished, officially distributed products
- Anyone for whom immediate domestic purchase and A/S matter
🎯 Final Verdict
The DuRoBo Krono actually builds out the idea of "what if you attached a physical dial to an E-ink reader." One-handed dial control, pocket size, Android 15's flexibility, and even AI notes — it's a really tempting combination for anyone who loves using e-readers or enjoys dial controls.
That said, being a first-generation crowdfunded product means you have to factor in software polish and E-ink's usual lag, and you'll need to check the purchase route in Korea too. It's less a perfectly finished product right now and more a "product headed in the right direction."
Still, it's worth keeping an eye on if you're someone who wants to put the phone down and focus on reading and note-taking, or if you just love the feel of a dial under your fingertip. I'm curious about that sensation of turning pages by rolling a dial in hand myself, so I've added it to my wishlist.
