The Pebble smart watch made a big return earlier in 2025, with new versions having a 30-day battery life, but lacking modern smartwatch features. Now, the company is going after the smart ring market with a similar concept.
Launched on Tuesday, the Pebble Index 01 is a ring designed to help you make voice notes quickly. The idea is to act as an external memory for the user, always on hand to handle audio recordings.
