The average American adult checks a phone 186 times a day, about 11.6 times an hour, with 85% reaching for it within ten minutes of waking. That means most of the small decisions in a day still begin with unlocking a screen, opening an app and tapping through the same steps. Hardware makers are now racing to move some of those moments off the phone, with Meta's AI glasses selling more than seven million units in 2025 while smart ring shipments grew 49% to about 4.3 million in the same year.
The software those devices connect to is changing just as quickly, since AI agents are expected to make at least 15% of day-to-day work decisions by 2028, up from none in 2024, while a third of enterprise software apps will include agentic AI, up from under 1%. As agents begin to act on their own, a person's role shifts from typing instructions to approving or rejecting what the agent proposes, which is a far smaller interaction than a full trip through a phone.
Aina, a consumer hardware company founded by Ultrahuman's former vice president of hardware, Apoorv Shankar, unveiled a $399 AI ring on 5 November 2026 that is built for exactly those quick decisions. The ring carries a small OLED screen that shows the three actions its software predicts you need next, along with a thumb control in the band that approves or rejects them with a flick, while pre-orders open today with shipping planned for January 2027.
New AI Form Factors
Essilor Luxottica sold about two million Meta AI glasses across 2023 and 2024, then more than seven million in 2025 alone, about 3.5 times as many in a single year (our arithmetic). The partners are now weighing production capacity of at least 20 million units. Glasses were the first AI device worn on the body to reach mass-market volumes, which showed that people will adopt new AI hardware when it fits into something they already wear.
The hand is the next obvious place for that kind of device, because it is already where people tap, swipe and confirm dozens of times an hour. A ring sits on the finger next to the thumb, so a control built into its band can turn a yes or no into a single movement that takes less than a second, without a phone ever leaving the pocket.
Smart Rings Go Mainstream
Oura has already turned the ring into a mainstream product, with paying members doubling in 2025 and again in 2026 to reach 5 million, revenue up 74% from 2024 to 2025 and about $61 million of net profit between October 2025 and June 2026. About a third of its new buyers say the ring is their first wearable, while the company was valued at about $11 billion in 2025 and set terms for a Nasdaq listing at up to about $15 billion in September 2026.
Across the market, smart ring shipments grew 49% in 2025 to about 4.3 million units, roughly eight times the 6% growth of smartwatches (our arithmetic), even though smartwatches still shipped 163.5 million units. Prices have settled into a narrow band, with Samsung's Galaxy Ring at $399, Oura's Ring 4 at $349 to $499 plus a $5.99 monthly membership and Ultrahuman's Ring Air at about $349, which shows that buyers already accept paying a few hundred dollars for a ring that tracks their health.
How the Aina Ring Works
The Aina Ring runs on a context-aware operating system that learns a user's habits by pulling in app usage, location and calendar details from their phone, Mac and connected AI agents, then predicts the three things they are most likely to need next. Those three actions appear on the ring's OLED display just before they are needed. A mechanical control in the band called the Shifter reads thumb movements in four directions, so a flick up approves a suggestion, a flick down rejects it and holding the centre button opens a voice channel.
The ring works in three modes. Aina Voice lets users talk to their connected agents through a built-in microphone and speaker, approve agent requests that appear as notifications and take phone calls by raising a hand to the ear. Aina Cues offers shortcuts such as booking the usual Uber to work just before a 9am departure or sending a running-late email before a meeting. Aina Remote turns the ring into whatever controller the moment needs, from a music remote to a meeting controller for the microphone, camera and notetaker or a remote for the TV.
The ring has a titanium body, offers up to 18 hours of battery life and works with iOS and Mac at launch, with more integrations to be announced after launch. In practice, the design means the most common actions of the day become a glance at the finger and a single thumb movement, which removes the passcode, the app search and the confirmation screens that a phone requires for the same task.
Pricing and Availability
Pre-orders open globally on 5 November 2026, with limited Super Early Bird units priced at $399 and global shipping planned to begin in January 2027. Aina's reservation page lists refundable deposits, a 30-day money-back guarantee and a one-year warranty, which lowers the risk for early buyers of a first-generation device.
At $399 the ring is priced level with Samsung's Galaxy Ring and inside Oura's range, yet it serves a different purpose, since health rings measure sleep, heart rate and activity while Aina's ring is built to act on the user's behalf. That puts a display, a thumb control, a microphone and a speaker on the finger for the price of a mainstream health ring.
From HCI Lab to Product
Shankar founded Aina in May 2025 after serving as vice president of hardware at Ultrahuman, the Indian smart ring maker. The company then spent its first 15 months operating in stealth as a human-computer interaction (HCI) lab, testing physical interfaces across everyday computing tasks. It showed three experimental AI interface concepts at CES in January 2026. In April it released Dune, a three-key keypad for the Mac that changes its controls to suit the app in use, which reached first place on Product Hunt and shipped to hundreds of early adopters.
Aina raised a $5.5 million seed round in July 2026 led by Redstart Labs, part of Info Edge, with 360 ONE, MIXI Global Investments, Antler and angel investors including Kunal Shah, Harshil Mathur, Shashank Kumar and Tikhon Bernstam. The company now has a 40-person team across San Francisco and Bengaluru covering consumer hardware, industrial design, engineering and manufacturing, while a controlled group of private pilot users has been testing the ring since early October to refine the hardware before launch.
Approvals as the Next Interface
Shankar's view is that AI is moving from following instructions to anticipating what people need, with proactive agents that learn a user's patterns, build on their context and then wait only for approval. In that world people will make hundreds of quick yes-or-no choices a day. Pulling out and unlocking a phone for each one will not work, so new hardware beyond the phone will be built around voice and fast approvals.
He frames the ring as the start of a new computing era, in the same line as the mouse and graphical interface that brought personal computing and the touchscreen and App Store that brought mobile computing. The data points in the same direction, because agents are expected to take on a growing share of everyday decisions over the next three years while people already check their phones 186 times a day. Aina is designed to close the gap between what agents can do and how quickly people can approve it.
Outlook
Aina plans a global launch built around the January 2027 shipping date, with more integrations to be announced after launch as it moves from private testing to a wider consumer audience. The first test will be whether the three-action screen and the Shifter feel faster than a phone for the tasks people repeat every day, from booking a ride to muting a meeting.
The wider shift is already under way, since glasses proved that people will wear AI on their bodies, Oura proved that a ring can become a mass-market business and AI agents are starting to make real decisions. Aina's ring is built around that last change. If agents keep taking on more of the work, the device that lets people approve that work with a flick of the thumb could become as familiar as the phone it is meant to spare.
