Now Pebble is expanding its product lineup into the smart ring market -- a segment currently dominated by the Finnish company Oura.
But Pebble's approach to smart rings is entirely different from all of its competitors.
First of all, the Pebble Index 01 ring does not measure any vital signs of its wearer: no heart rate, no activity, nothing.
Its only function is a button that the user presses. When the button is pressed, the ring records audio for as long as the button is held down, up to a maximum of five minutes.
The recorded audio is transferred wirelessly to the phone paired with the ring, where it is converted into text. According to Pebble, the app can transcribe audio into text in 99 languages. If the user chooses, the recording can also trigger an on-device AI that executes spoken commands, such as setting a calendar reminder.
However, the most surprising feature of the ring is related to its charging. Or rather, to the fact that Pebble's smart ring cannot be charged at all, in any way.
Once the ring's battery runs out, it becomes recyclable waste that the manufacturer hopes users will send back to Pebble for proper recycling. The battery lasts for approximately 12–14 hours of recordings.
The company frames this limitation by saying that "the Pebble ring never needs to be charged".
The ring includes a 30-day warranty and costs $75 during preorder (appx. €65). After the preorder period ends, the price will rise to $99.
Pebble Index 01 will begin shipping in March 2026.
