Wearables and smart rings are trending product categories, and now two former Meta employees have launched another new smart ring brand called Sandbar.

Sandbar’s first product is the Stream smart ring, available for preorder for $249 and set to ship in summer 2026. The Stream doesn’t track your heart rate or steps like the Oura Ring, nor is it an AI device like Bee, the wearable company recently acquired by Amazon.

So, what does it do?

The Stream has two primary functions: It acts as a voice recorder to capture and transcribe your thoughts, and it lets you control music with hand gestures.

Of course, your phone and various AI chatbots can already record and transcribe notes. And most headphones and earbuds feature touch controls that allow you to control your music with your hands.

The Sandbar website states that Stream is a “fast, private, & effortless way to capture thoughts in the moment.” A companion app organizes your voice notes into reminders, calendar events, or notes; however, users will need to pay $10 per month for a Pro subscription. A free tier “includes unlimited notes and limited chats.”

In terms of design, the new smart ring has an aluminum outer surface, a resin inner surface, and a glass touchpad. Sandbar says the ring is “resistant to rain and handwashing.”

TechCrunch reports that Sandbar was founded by former Meta employees Mina Fahmi and Kirak Hong. You can preorder the ring on the Sandbar website.
