Description

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.

FAQs

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).

When do I pick my size?

You'll be able to pick your ring size and color after placing a pre-order. If you have a 3D printer, you can print our CAD designs to try on. We're also planning a sizing kit. You can view the measurements of the inner diameter of each ring size. Index 01 is available in US ring sizes 7 to 13 in all three finishes (polished gold, matte black and polished silver). Size 6 is available in polished gold only. Do you want a size 14/15 ring? Sign up here for updates.

How long does the battery last?

Roughly 12 to 15 hours of recording. On average, I use it 10-20 times per day to record 3-6 second thoughts. That's up to 2 years of usage.
