A newly filed class-action lawsuit claims Oura Ring cannot accurately determine sleep stages because it relies on AI inference rather than direct brain-wave measurement, likening its accuracy to a coin flip. The complaint argues Oura is exploiting sleep-deprived consumers by marketing statistical estimates as reliable science. Verge writer Victoria Song notes that no wearable device measures brain activity directly, since all such gadgets rely on motion and physiological proxies interpreted through algorithms.
ZDNET's guide clarifies that despite USB unifying device charging, wall outlets worldwide still differ wildly in plug shape and voltage output, from 100V in Japan to 230V in Paraguay. It distinguishes universal travel adapters, which only change plug shape, from voltage converters, which actually change electrical output—two very different tools travelers often confuse.
Apple published a support document listing the devices that fully support Wi-Fi 7, following today's update to the Mac mini and Mac Studio, which now include the technology for the first time. The list differs from Apple's broader compatibility list, since Wi-Fi 7 networks remain backward-compatible with older Wi-Fi 6E devices that can still connect but lack full feature support.
The FDA has granted approval to a wearable sensor capable of monitoring both blood glucose and ketone levels simultaneously, marking the first authorization of its kind. The device is designed to give users continuous, real-time readings without separate testing tools for each metric.
The FDA has authorized the Libre Duo 10 Day Continuous Dual Glucose Ketone Monitoring System for diabetes patients aged 2 and up. It is the first wearable in the U.S. to continuously track ketone levels and the first worldwide to combine continuous ketone and glucose monitoring in one device. Sensors measure both substances every minute in fluid beneath the skin and send readings wirelessly to a paired smartphone.
Apple's Find My iPhone can be turned off manually via Settings, but only after disabling Stolen Device Protection, a security feature enabled by default since iOS 26.4. Users are advised to do this at home to avoid built-in delays meant to deter thieves who know a device's passcode. Location sharing with specific contacts can also be stopped individually through the Find My app without disabling the entire feature.
Costco has launched an early round of Labor Day 2026 promotions covering televisions, smartwatches, Apple devices and other electronics. The deals are being aggregated and vetted by outlets like ZDNET, which test and compare pricing across retailers before recommending items to shoppers.
Nearly a decade after Geoffrey Hinton predicted AI would replace radiologists, the profession has instead grown, with practitioner numbers projected to rise more than 26% over three decades. About three-quarters of the 1,400 AI-enabled medical devices cleared by the FDA target radiology, ranging from tools that draft reports and flag urgent cases to systems that can spot abnormalities humans miss, such as AI-assisted colonoscopies detecting more polyps than standard procedures.
Apple released a support page listing 50 ways users can adapt their devices as they age, organized into ten categories covering vision, hearing, mobility and cognition. The list draws mostly on existing accessibility settings, such as enlarging text, boosting contrast, and Sound Recognition, which can alert users to doorbells, alarms or appliance beeps. The release coincides with Apple's 50th anniversary and highlights features many customers may not know already exist.
In the latest episode of the Apple @ Work podcast, host Bradley Chambers and 9to5Mac's Arin Waichulis discuss Apple's move to impose caps and cool-down periods on submissions to its bug bounty program. The episode explores how these restrictions could change the way security researchers interact with Apple's vulnerability reporting system.
Google is rolling out an experimental Gemini feature called Device Help on Pixel 11 and Pixel 11 Pro phones, letting users troubleshoot issues like battery drain or Wi-Fi problems, adjust settings such as brightness or dark mode, and get explanations of Pixel features using plain language instead of navigating menus. The feature carries a 'Labs' tag, signaling it's still experimental, and Android Authority's hands-on testing found it worked well for some tasks but gave inconsistent guidance for others, such as Magic Capture instructions.
CNET published a guide recommending smart devices to upgrade home desks and offices, starting with a smart surge protector like Tapo's model that lets users label, remotely control, and track energy use of connected devices. The guide also highlights smart speakers, such as Google's newest model, for hands-free reminders, timers, and voice commands while working.
