Pebble’s Index 01 is a smart ring that records voice memos on the go

Pebble, which returned to the smartwatch scene earlier this year, has introduced its first smart ring. It does not require an Internet connection, subscription or battery charging.

The Pebble Index 01 is built from 316 stainless steel with a built-in battery. Other trimmings include a liquid silicone rubber button and microphone, and the ring is made for one purpose: to act as an external memory for your brain.

To record with it, the user holds the button, whispers their thoughts at the Pebble Index 01 to capture it as a note, and sets it as a reminder or saves it for later use.

Because the Index 01 does not rely on cloud services, all voice memos are processed on your connected phone using open-source speech-to-text and AI models that support over 99 languages.

The connection between the smart ring and your phone is also encrypted. When your phone is out of range, Index 01 can still save up to five minutes of audio for syncing later.

Wait, the Pebble Index 01 has a built-in battery but no charging?

Pebble says Index 01 is intentionally a single-use, non-rechargable product for two reasons:

• Most users are more likely to lose the charger long before the battery runs out.
• Adding charging hardware would make the ring bulkier and more costly.

Inside is a silver-oxide battery rated for 12 to 15 hours of recording, translating to roughly two years of typical use. When the battery is nearing depletion, the Pebble app will prompt you to order a replacement ring.

Other specs include water resistance up to 1 metre depth, alongside Android and iPhone compatibility, and configurable single-or double-click actions for tasks like taking photos or toggling lights.

Availability and Pricing

Priced at US$75 (~S$97), the Index 01 is now available for pre-order on Pebble’s website. Worldwide shipment begins in March 2026, after which the price will adjust upwards to US$99(~S$128).
