Pebble Index 01: a minimalist smart ring for recording thoughts

Pebble has announced the Index 01, a near‑minimal smart ring designed to capture voice notes. The ring includes a microphone, a physical push‑to‑record button and basic speech‑to‑text — the goal is to make leaving quick reminders or ideas as effortless as whispering them into your hand.

Unlike many modern gadgets, the Index 01 avoids heavy on‑device AI: it simply records and sends audio to a notes app or saves entries for later. Pebble says the ring is water‑resistant, works with iPhone and Android, and is intentionally privacy‑minded — it only records when you press the button, not continuously listening.

Key specs and features

• Push‑to‑record microphone that captures short voice notes and can send them to your notes app.
• Speech‑to‑text support; optional integrations with AI agents and services are planned (open‑source approach).
• Water‑resistant, sized like a wedding band and designed to be worn daily.
• Extremely long battery life — Pebble claims it lasts “years” and needs no charging.
• No subscription required; preorder price $75, rising to $99 when shipping begins in March.

Privacy, openness and integrations

Pebble positions the Index 01 as an “external memory” rather than an always‑listening assistant. Because recording requires a deliberate button press, the design reduces passive privacy risks. The company also says the product is open source and expects the community to build integrations with services like ChatGPT, Beeper and other voice agents in the future.

Who might like it

This ring targets users who want a low‑friction way to capture fleeting ideas without pulling out a phone. Creatives, students, commuters and anyone who hates fumbling for a device may find it appealing. It’s also a niche pick for people who prefer simple, single‑purpose wearables rather than feature‑heavy smart jewelry.

Preorders are open now; shipments start in March. For the original report and more context, see the coverage: Engadget — Pebble’s Index 01.
