Amazon has spent nearly two decades perfecting the Kindle, turning it into the default eReader for millions of people, and in all that time they’ve steadfastly refused to shrink it down to pocket size or open it up to the broader Android ecosystem. They had every opportunity to merge the best parts of their Kindle line with the form factor of a smartphone, creating a distraction-free reading and productivity device that could actually fit in your jeans pocket and run the apps you already use. Instead, they kept the Kindle locked into its walled garden, kept it at 6 inches or larger, and left a gaping hole in the market for anyone willing to build what they wouldn’t. DuRoBo took that opportunity and ran with it, launching the Krono, a 6.13-inch E Ink tablet running full Android 15 that costs $279.99 and does exactly what Amazon has spent years pretending nobody wants.
The Krono packs an E Ink Carta 1200 display at 300 PPI (matching the sharpness of a Kindle Paperwhite), an octa-core processor, 6GB of RAM, 128GB of storage, a 3,950 mAh battery, and a unique side-mounted Smart Dial that controls screen refresh, frontlight adjustment, voice recording, and web browsing through a single rotary knob. It weighs just 173 grams, measures 154 x 80 x 9 mm, and is available in black or white from DuRoBo’s site or Amazon US. The pitch is straightforward: it’s an eReader, a voice note-taker, a podcast player, and a music device all in one, built on an open platform that lets you install whatever reading app, productivity tool, or communication software you actually want to use. It launched in August 2025 and started shipping in September, quietly carving out space in the niche that BOOX’s Palma lineup has been dominating for the past year.
Designer: DuRoBo
Six gigs of RAM in an E Ink device is borderline excessive in the best possible way, especially when most eReaders ship with 2GB or less and struggle the moment you try to run anything beyond the stock reading app. The 128GB of storage means you can load an absurd library of ebooks, PDFs, audiobooks, and whatever else without ever worrying about running out of room. Running Android 15 (not some ancient fork, but the actual current OS) gives the Krono access to the full Play Store ecosystem, which is exactly what Amazon has been allergic to for years. You want Kindle, Libby, Moon+ Reader, Pocket, Instapaper, Obsidian, and Spotify all on one device? The Krono lets you do that. A Kindle will let you read Kindle books and maybe listen to Audible if you’re lucky. That’s the entire difference.
The Smart Dial highlights DuRoBo’s industrial design philosophy most clearly – instead of burying every interaction behind capacitive touch menus (which E Ink refresh rates make tedious), they mounted a physical rotary dial on the side of the device that you can press and rotate to trigger different actions depending on context. It’s a design choice borrowed more from cameras and audio gear than from tablets, and it gives the Krono a tactile, mechanical quality that most E Ink slabs completely lack. The back of the device features what DuRoBo calls the Axis, a strip housing six small breathing lights that glow softly on a schedule to gently nudge you back toward focused reading or work. It’s a wellness-adjacent UX detail that could easily feel gimmicky, but in the context of a device explicitly marketed as a “focus hub,” it at least makes thematic sense. The whole package is clearly designed to feel intentional and calm, a deliberate counterpoint to the dopamine-optimized chaos of a smartphone.
DuRoBo is positioning the Krono hard into the distraction-free productivity and mindfulness lane, framing it as the device you reach for when you want to read long-form content, capture ideas through voice notes, or listen to podcasts without getting dragged into Instagram or TikTok. The dual-tone frontlight (warm and cool adjustment) and the paper-like texture of the Carta 1200 display are meant to make extended reading sessions comfortable in a way that backlit screens never quite manage. The built-in speaker and Bluetooth support let it double as a surprisingly capable audio player for music, audiobooks, and podcasts, which gives it utility beyond just being a reading slab. The open Android platform means you can customize it to fit whatever workflow you actually need, whether that’s Notion for notes, Pocket for saved articles, or Spotify for background music while you write. Amazon would never build this, because opening the Kindle platform would undermine their entire content ecosystem lock-in strategy.
The Krono is available now for $279.99; with a fitted TPU case is sold separately, designed to accommodate both the Smart Dial and the Axis breathing lights without blocking either. At that price point, it’s competing directly with the BOOX Palma (which runs around $280 depending on configuration) and sits well above Amazon’s Kindle Paperwhite but below their Kindle Scribe. Whether the Smart Dial, the breathing lights, and DuRoBo’s focus-first branding are enough to justify choosing it over a Palma or just installing a launcher on a Kindle will depend entirely on how much you value that design identity over raw software polish.
