Aina puts an OLED screen on a $399 AI ring

Aina has opened preorders for an AI ring with an OLED screen and physical controls, starting at US$399 ahead of planned shipments in early 2027. Worn on the index finger, it uses thumb gestures to approve suggested actions, control software and handle calls, putting a small working interface on the hand. ^[1]

Four titanium parts surround 140 components, according to Aina, with the display protected by glass. Seven gestures cover swipes, button presses and holding the control to speak, while the screen shows a suggestion or a hint about the next action. The same display is fitted across seven ring sizes, with the band changing to accommodate the finger. That preserves the area available for text and controls even in the smaller sizes. ^[1][3]

Through a feature called Cues, Aina says its software learns patterns involving time, location and calendar activity, then presents one suggested action when a similar situation arises. A regular departure might produce an offer to book a ride, for example, with an upward swipe confirming the request. Ignoring the suggestion leaves it unapproved. The design gives the wearer a chance to inspect what the software proposes before allowing it to proceed, making the little screen part of the control mechanism rather than decoration. ^[2]

Services are connected through Aina’s iPhone app, with a separate Mac app handling meeting controls, dictation and gestures assigned to applications. The company’s published requirements are iOS 18 or later and macOS 15 or later; Android and Windows are unsupported. Meeting controls also require the Mac to be nearby, so their usefulness depends on the paired computer and its software, rather than the ring acting as an independent computer. Updates arrive from the iPhone over Bluetooth, with a failed update reverting to the previous version. ^[2][3]

Holding the button opens voice input for requests or notes, while other gestures can pause music, skip tracks or change volume. Aina also describes displaying an incoming caller’s identity and answering a call from the ring. It says routine learning happens on the wearer’s own devices and saved voice notes remain on the paired device. That description does not establish that every connected service processes requests locally, particularly when an action involves an external booking or AI service. ^[1][2]

The company showed three interface concepts at CES in January and announced a $5.5 million seed round in July, before revealing the ring and opening orders on 5 November. Its team operates from San Francisco and Bangalore. ^[4]

Early access pricing starts at $399, with the Amber Gold finish costing $50 more and a stated list price of $499 for the standard finishes. Orders are paid in full, with a sizing kit supplied before the ring is made and a charging dock included. ^[3]
