US EditionAfter Bringing Pebble Watches Back, the Next Thing's a Ring
Pebble's Index 01 smart ring offers up to two years of use with 10-20 daily voice notes and syncs encrypted audio to a phone app without cloud dependency.
- Core Devices started Index 01 preorders today at $75, rising to $99 after shipments begin in March 2026.
- Pebble founder Eric Migicovsky built the Index 01 as a simple capture tool, calling it an "external memory" while Core Devices has shipped new watches and logged over 25,000 preorders.
- Pressing and holding the ring's button records audio, streaming encrypted clips to the Pebble app where an on-device LLM processes speech-to-text; the hearing-aid battery lasts 12–14 hours and supports a recycling program.
- Positioning itself against subscription-heavy rivals, Pebble emphasizes local processing and no subscription, with the Index 01 focusing solely on voice notes unlike Sandbar's Stream Ring.
- Programmable single and double presses let the Index 01 smart ring send recordings to custom apps or servers, while Pebble's open-source code and planned integrations with ChatGPT and the Model Context Protocol invite developers and hobbyists to expand features.
