Tell this smart ring all your secrets, and it'll talk back to you

Smart rings are all about tracking fitness, right? Wrong. The Sandbar Stream Ring is not about fitness at all, and is instead a voice assistant on your finger, ready to save notes and talk through ideas.

What’s also interesting is how this is clearly an AI gadget, but AI is not mentioned on the product’s webpage at all. Here’s what it’s all about.

A mouse for voice?

The Sandbar Smart Ring is actually two products, the smart ring and an app called Stream, which is where the AI voice assistant lives. The company pitches the setup as a “mouse for voice,” likely due to the touch panel on the ring which lets you interact with the assistant and control music playback from your phone.

Sandbar’s CEO Mina Fahmi introduced the product on X, and called the Stream app, “a self-extension to capture your thoughts and build ideas,” adding the app is, “part inner dialogue and part notes.”

Unusually, Fahmi says talking to the Stream Ring is like talking to yourself, but it then responds back in a way that’s personalized to you, building a conversation around your thoughts. It’s less AI assistant, more inner voice, with some added feedback. Take a look at the promotional video to get an idea of what the interaction will be like.

Organize thoughts

The Stream Ring has microphones and a touchpad, and is made to be worn on the index finger of your dominant hand, according to TechCrunch. Fahmi said he never wanted to talk loudly into earbuds to save voice notes, so the Stream Ring’s microphones are tuned to hear whispers, keeping your interaction with the app private.

You can use headphones with the Stream Ring if you want, and if you don't have your smart ring with you, the Stream note-taking app can use your phone’s microphones instead. However you record notes, the Stream AI organizes and edits them, and you can look back over them in the app.

Unlike some other AI assistants, the Stream Ring’s microphones aren’t always listening, and require activating with the touchpad. One unexpected aside in Fahmi’s conversation with TechCrunch revealed there will be a personalization feature, where the Stream’s “inner voice” can be made to sound a bit like your own.

When will it be released?

The Sandbar Stream Ring will be made from aluminum with a resin inner surface, and the touchpad will be glass. The company promises water resistance sufficient to protect against rain and handwashing, and that the battery will last “all day.”

The Sandbar Stream Ring can be preordered now, but it won’t be released until sometime in summer 2026, so you’ll be getting in early.

There are two versions, a matte silver ring for $249 and a polished gold version for $299, and it’ll come in sizes five to 13. Unfortunately, at the time of writing, the company has only announced an iOS app and U.S. availability.

A subscription package will be an option too. In the free tier you’ll get unlimited notes but limited chats. Pay $10 per month for Stream Pro, and you’ll get unlimited interactions and early access to future features. The Stream Ring will include three-months of Stream Pro.
