Years on a Charge: Pebble's New Voice Ring

Pebble, the once-popular smartwatch brand, has resurfaced with new wearables, including the unique Index 01 ring. Unlike feature-rich smart rings, the Index 01 is designed for a single purpose: capturing voice notes with exceptional reliability. Its minimalist design features a microphone, a hearing aid battery, and a tactile button.

This innovative ring promises unparalleled battery life, potentially lasting two years with typical daily use on a single charge. Voice notes are sent via Bluetooth to your phone, where an open-source app transcribes them using a local large language model. This approach ensures user privacy, as no data is transmitted online unless an optional backup is chosen.

The Index 01 supports local AI functions like creating notes, setting reminders, and managing music playback. It's also designed to be hackable, with open-source AI models and webhook support for custom integrations. Available in multiple finishes, it preorders for $75, with worldwide shipping starting March 2026 at a $99 price point.
