External Memory For Your Brain
Catch your best ideas before they slip through your fingers
Do you ever have flashes of insight or an idea worth remembering? This happens to me 5-10 times every day. If I don't write down the thought immediately, it slips out of my mind.
Introducing Pebble Index 01 - a small ring with a button and microphone. Press the button, whisper your thought, and it's sent to your phone. It's added to your notes, set as a reminder, or saved for later review.
It's private by design (no recording until you press the button) and requires no internet connection or subscription. It’s as small as a wedding band and comes in 3 colours. It’s made of durable stainless steel and is water-resistant. Like all Pebble products, it’s extremely customizable and built with open source software.
Here’s the best part: the battery lasts for years. You never need to charge it.
Pre-order today for $75. Worldwide shipping begins in March 2026, afterwards the price will go up to $99. For more details please read the announcement post.

How does it work?
People usually wear it on the index finger. Inside the ring is a button, a microphone, a Bluetooth chip, memory, and a battery that lasts for years. Click the button with your thumb, talk into the mic, and it records to internal memory. When your phone is in range, the recording is streamed to the Pebble app. It's converted to text on-device, then processed by an on-device large language model (LLM) which selects an action to take (create note, add to reminders, etc).
Is it secure and private?
Yes, extremely. The connection between ring and phone is encrypted. Recordings are processed locally on your phone in the open-source Pebble app. The app works offline (no internet connection) and does not require a cloud service. An optional cloud storage system for backing up recordings is available.
Is there a warranty?
Yes, we warrant against manufacturing defects for 30 days after you receive your order. See our full warranty.
How does shipping work?
All prices are in USD.
All shipments are sent from our warehouse in Asia via courier with tracking. Be prepared - your country may have taxes, tariffs, customs or duties fees. Shipments are sent 'DDP' which means that all taxes, tariffs and duties are prepaid. We'll contact you when your ring is ready to confirm your address and request any necessary payments.
