Reetle SmartInk I: iPhone Case with E-Ink Display for Glare-Free Reading (2025)

Tired of eye strain from reading on your phone? Imagine reading books and comics on your iPhone without that harsh screen glare! That's the promise of the REETLE SmartInk I, an innovative iPhone case featuring a built-in E-Ink display on the back. It's not just a case; it's a potential game-changer for how we consume digital content.

The REETLE SmartInk I isn't just a pretty face; it's designed to be a versatile tool. This isn't your average phone case; it integrates an E-Ink display on the rear of the case, allowing you to comfortably read books and comics without the dreaded screen glare. Think of it as a Kindle attached to your iPhone, offering a more pleasant reading experience, especially in bright sunlight. But here's where it gets interesting: This multipurpose accessory is powered by AI, enabling audio recording and real-time transcription.

As an E-Ink reader, the SmartInk I's secondary screen stands out with its low-power consumption. This means you can enjoy hours of reading without significantly draining your iPhone's battery. The display allows you to view documents, articles, and notes even in brightly lit conditions without needing to unlock and use your main phone screen. This could be a huge win for anyone who spends a lot of time reading on their phone, offering a less distracting and more comfortable way to engage with text.

Beyond just reading, the SmartInk I leverages its AI system to assist with comprehension. And this is the part most people miss: The case can summarize text, highlight key points, and even organize information into bullet points, all directly on the E-Ink display. Imagine reading a lengthy article and having the SmartInk I automatically extract the core takeaways for you. This functionality could be a boon for students, researchers, or anyone who needs to quickly digest large amounts of information. The screen is designed for up to ten hours of continuous use for both reading and recording due to its energy efficiency.

But the versatility doesn't stop there. The REETLE SmartInk I also functions as a second screen. You can use it as a digital business card to share your contact information instantly or display QR codes linking to your social media profiles. Since it has Bluetooth and WiFi, you can sync content from your iPhone to the E-Ink display, similar to using a second monitor on your laptop. This makes it incredibly easy to upload files to cloud storage after recording interviews or meetings.

The case itself isn't just about functionality; it's designed with protection in mind. Corner guards and a layer of tempered glass shield your iPhone from drops and scratches. Despite all its features, the case maintains a slim profile, adding only 4 millimeters to your phone's thickness, ensuring it remains easy to carry and hold. Even when you're not actively using it for reading or other tasks, the E-Ink display can show your to-do list or the time, potentially reducing your overall screen time, exposure to blue light, and eye strain.

The REETLE team has launched a Kickstarter campaign to bring the SmartInk I to market, with a planned release in early 2026.

Is this the future of phone cases? Could this solve the problem of eye strain and digital fatigue? Or is it just another gadget promising more than it can deliver? What do you think? Let us know in the comments!
