Researchers at ETH Zürich have built a quadcopter called FlexiQuad that replaces a rigid frame with a flexible ring-shaped fuselage. The design lets the drone bounce off obstacles like tree trunks, squeeze through narrow gaps, and continue flying instead of crashing to the ground.
Startup Aina has unveiled a smart ring featuring a tiny OLED screen, a microphone, and touch-capacitive controls that let wearers manage AI agents and connected devices. The ring is designed to learn user habits from a phone or PC and surface relevant prompts, such as approving an agent's action, directly on its display. It is priced at $400, available for pre-order now, and expected to ship in early 2025.
Casio has announced the CRW-002, a follow-up to its 2024 ring watch that mimics the design of the classic Casio A168 from 1995. The device offers a seven-segment LCD display, 12/24-hour format switching, a 1/100-second stopwatch, auto calendar, water resistance, and an LED backlight. It launches this November in silver for $135 and gold for $155, available in one ring size with included spacers for adjustment.
Amazon is selling the Oura Ring 4 Smart Ring in Ceramic Midnight for $279, down from its $399 list price, a 30% discount that matches the lowest price it has ever hit. The ring tracks sleep, recovery, activity, heart rate, temperature and stress without a screen, using Oura's Smart Sensing technology, and the ceramic version is built from scratch-resistant zirconia ceramic with a battery life of roughly 5 to 8 days.
Samsung announced that its Galaxy Ring and Galaxy Watch devices received FDA approval in July for an upgraded sleep apnea detection feature. The AI-powered tool now tracks breathing disruptions hourly and can report mild, occasional or frequent apnea after users log at least five hours of sleep on two nights within a ten-day span. The feature is also rolling out to the Galaxy Watch 9, with Watch 7 and 8 support planned via future updates.
Samsung has begun rolling out an improved sleep apnea detection feature to the Galaxy Watch 9, Galaxy Watch Ultra 2, and Galaxy Ring in the US and South Korea. The update follows clearances from the FDA and South Korea's MFDS, and arrives through the Samsung Health Monitor app. Instead of a simple yes/no result, the algorithm now tracks blood oxygen drops and breathing disruptions across two sleep sessions within a 10-day window to gauge severity.
Amazfit has pushed firmware version 2.9.0.1 to its Helio Ring, replacing the device's Readiness feature with a new system called HybridCharge that shows all-day energy status graphs in the Zepp app. The update also improves heart rate tracking accuracy and adds automatic stress measurements taken every five minutes.
Ring security cameras and video doorbells support a lesser-known ecosystem of third-party AI apps that extend the devices' object-recognition features for specialized monitoring tasks. One example, DumpWatch, costs about $8 a month and uses Ring's AI to detect illegal dumping, generating timestamped PDF reports for complaints or police filings. Most of these add-on apps require an existing Ring subscription plus an extra monthly fee.
Amazon is selling Ring's newly released Battery Doorbell 2K at a $55 discount. The device records in 2K resolution with up to 6x zoom and a 140-by-140-degree field of view, and offers live view, two-way talk, and motion-triggered phone alerts. It runs on a USB-C rechargeable battery or can be hardwired to an existing 8-24 VAC doorbell system.
FromSoftware has delayed The Duskbloods, its multiplayer game exclusive to Nintendo Switch 2, from its planned 2026 release to sometime in 2027. The studio said an August network test showed strong interest in the game's combat, strategic depth and player expression, prompting it to take extra time to refine rules and balancing.
Android Authority ran a reader poll asking which wearable people would buy instead of the newly launched Fitbit Edge. Among over 2,000 votes, the screen-free Fitbit Air won with 26%, followed by the Samsung Galaxy Fit 3 (22.5%), Fitbit Charge 6 (20.9%), Pixel Watch 5 (20.3%), and Oura Ring 5 (6.1%), with 4.2% naming other devices like the Garmin Venu 3 and Fitbit Sense 2.
Ultrahuman's Ring Pro smart ring went on sale Wednesday at Best Buy, Target, Walmart and Ultrahuman's own website, with wider retail rollout to over 1,000 Target and Walmart stores planned in coming weeks. The $479 ring tracks heart rate, sleep, stress and other metrics without a subscription, launching just six days after Oura filed a new patent infringement complaint against Ultrahuman seeking a US sales ban.
