**Pebble Unveils a Revolutionary Smart Ring: Index 01**

Get ready to revolutionize the way you capture fleeting thoughts with Pebble's latest innovation: the Index 01 smart ring. This wearable device, designed by Eric Migicovsky, is set to become an essential tool for anyone looking to jot down quick ideas or reminders on-the-go.

The Index 01 is more than just a smart ring - it's an "external memory" for your brain. Unlike other multifunctional smart rings that focus on tracking health and fitness, the Index 01 has a single purpose: to capture and record your thoughts. With its built-in microphone, you can simply press and hold the button to activate recording.

The Index 01 is made of stainless steel, water-resistant, and comes in three sleek colors: polished silver, polished gold, and matte black. The ring itself is as small as a wedding band, making it comfortable to wear on your index finger. The single-button design provides a satisfying click-feel, perfect for one-handed use.

So, how does the Index 01 work? Audio recordings are saved to internal memory, streamed to the Pebble app on your phone (available on both iPhone and Android), converted to text, and then processed by an on-device large language model (LLM). This enables the Index 01 to turn your recorded thoughts into actionable tasks such as adding them to your notes or reminders.

Migicovsky emphasizes that the Index 01 is not a device for constant recording or AI-driven conversations. Instead, it's a simple gadget built with privacy at its core. The connection between the ring and phone is encrypted, ensuring that all recordings are processed on-device before being sent to your phone. This means no recordings are ever stored in the cloud.

While the Index 01 may have some limitations - its battery life lasts only around 12-15 hours, depending on usage - Migicovsky points out that it's a single-purpose device designed for simplicity and minimalism. Users will be notified via the Pebble app to order a replacement ring when it needs recycling, which is estimated to be every 2 years or so.

The Index 01 is available for pre-order today at a discounted price of $75, but will increase to $99 after shipping starts in March 2026. The smart ring comes in eight sizes (6-13) and three colors, ensuring that you can find the perfect fit for your style.

But what really sets the Index 01 apart is its open-source nature, allowing users to hack and customize the device to their liking. You'll be able to program the button for single and double presses, add your own voice actions, or even send audio recordings to your own app or server - all in line with Pebble's principles of DIY innovation.

Get ready to revolutionize the way you think and create with the Index 01 smart ring. With its sleek design, innovative technology, and commitment to simplicity and privacy, this wearable device is set to become an essential tool for anyone looking to capture their ideas on-the-go.
