If you’re like me and have ten zillion unorganized thoughts jotted down in your smartphone’s notes app, then the new Index 1 ring might be for you. This small and lightweight wearable device, brought to you by the OG smartwatch brand Pebble, features a single tactile button, a built-in microphone and not much more.
Similar in concept to the Stream Ring from Sandbar, the Index 1 is an always-with-you, ring-based audio note taker that plays nicely with both Android and iOS devices. Here’s everything you need to know about it.
Pebble Index 01: Price and availability
Preorders for the Pebble Index 01 are open now. $75 secures your ring, which is expected to ship in March 2026. After the preorder period, it will cost $99.
Pebble Index 01: Sizes and finishes
The Pebble Index 01 will be available in polished silver, polished gold and matte black, with sizes ranging from six to 13.
Pebble Index 01: Design
Pebble says that the Index 01 is no bigger than a wedding band and weighs next to nothing. The device is primarily stainless steel, while the button is silicone rubber. Water resistance is 1 meter, so you shouldn’t need to remove it when washing your hands or doing the dishes.
Pebble Index 01: Key features
When an important thought pops into your head, users need to simply press and hold the small clicky button on the Index 1 ring to record themselves. With discretion in mind, the device can pick up even a whisper.
Then, once the Index 01 is back in range of your smartphone, the audio is transferred and interpreted by an open-source speech-to-text AI (run locally within the companion app) that creates a transcription and analyzes the audio for any actions, like adding an event to your calendar or starting a timer.
By the way, the speech-to-text model used also supports over 99 languages.
Users can store up to five minutes of audio directly on the ring itself before needing to pair with their smartphone and offload it. In addition to recording audio, users can assign secondary functions to the Index 01 ring when they double-tap or triple-tap the button.
Of course, the new Pebble Index 01 ring will work seamlessly with the brand’s latest smartwatch, along with the Pebble Time 02, coming in the new year.
Pebble Index 01: Privacy
To ensure maximum user privacy, audio processing and storage occur locally on your smartphone. The ring also only records when the button is pressed and held, not simply pressed.
Pebble Index 01: Battery
The Pebble Index 01 ring uses a small, non-rechargeable hearing aid battery intended to last the life of the device, at which point, Pebble wants you to send it back for recycling and presumably, a discount on a new one.
Pebble expects the Index 01 to last users for several years. However, it’s worth noting that this isn’t the device for dictating your next novel. In total, the battery is good for between 12 and 14 hours of recording.
Pebble Index 01: Outlook
When Pebble sprang back from the dead earlier this year, I was surprised. However, the hottest smartwatch brand of 2010 quickly launched two new, tempting wallet-friendly models, which run on the now-open-source Pebble operating system, owned by Google (an eternity ago, Fibit ate up Pebble before Google ate up Fitbit).
At first glance, the Index 01 ring seems like an odd move for Pebble, but once you consider the hackability of the product beyond its initial intent, note-taking, it all begins to make sense.
The concept of an always-with-you, discreet device that can record and transfer all your deepest thoughts to easily readable text sounds genuinely useful. However, I’m a little more interested in being able to double-tap a button on my ring to unlock my house’s smart doorknob, or triple-tapping to fire up Rock Lobster on the stereo.
Ultimately, I think this sort of customization is what could potentially make the Pebble Index 01 ring take off.
