Pebble’s New Smart Ring Is Only $75, Made To Record Ideas Before You Forget

Pebble’s new smart ring isn’t designed to replace your smartwatch or compete with the likes of the Oura Ring 4. The Pebble Index 01 is instead built to record your ideas and reminders when inspiration strikes without using your phone.

There’s a small button on the ring to tap to record your whispers into the ring’s microphone. It will send those short recordings directly to your phone.

The device uses an on-device large language model (LLM) to decide what to do with the recording. For example, it can add a new note, or it may create a reminder. The ring itself can store up to five minutes or audio before it needs to reconnect to your phone. Pebble’s software works with both iPhone and Android devices.

Pebble designed the Index 01 to record those ideas that often slip out of your mind unless you write them down. Head of Pebble, Eric Migicovsky, speaks about how he often finds he comes up with ideas when riding his bike, but is unable to write them down before he forgets them.

The brand assures customers the ring is only recording after a button press, and it says “your thoughts are processed by open source speech-to-text (STT) and AI models locally on your phone” for extra security.

The smart ring is exclusively designed to make recordings as there’s no speaker, activity tracking or other tech. However, Pebble is encouraging users to make use of the device outside of recording calling it “customizable and hackable.”

It says it will open the ability for others to build new functionality for the smart ring, such as a double press of the button to take a photo from your phone, or turn on your smart lights. Migicovsky even suggests it working to talk directly with ChatGPT’s Voice Mode.

It’s available in US ring sizes from six through to 13, although it doesn’t currently provide a ring sizing kit unless you have a 3D printer at home.

The ring comes in either polished silver or gold, or a matte black. It’s made of stainless steel, aside from the button which is liquid silicone rubber. The ring itself is water-resistant up to a meter.

You can’t recharge the Pebble Index 01. It’s designed to be one use product, but the brand estimates its battery will last for around two years. That’s based on an average of 10 to 20 recordings a day at a length of between three to six seconds.

Pebble encourages users to send the device back for recycling when it’s out of juice, suggesting customers should then buy a new ring to replace it.

It costs $75 at preorder, before jumping up to $99 when Pebble has the product officially on sale. The ring will be released at some stage in March 2026.
