Samsung has launched a new lineup of wearable devices, including the all-new Galaxy Ring, as well as the Samsung Galaxy Watch Ultra, Watch7, and Buds3 series. The Galaxy Ring is similar in concept the Oura Ring: a health-tracking device small enough fit into a ring on your finger. The Ring is designed to be worn 24/7. It weighs as little as 2.3 grams (thanks to a titanium frame), has a battery that lasts up to seven days, and has 10ATM (+IP68) water resistance. It's available in three colors (black, silver, and gold) and nine sizes. The comprehensive sleep monitoring includes heart rate, breathing, movement, and snoring. It also monitors skin temperature to track menstrual cycles. The Ring automatically detects and tracks walking and running activity. A double-pinch gesture can interact with your phone, taking a picture or dismissing an alarm. It also works with Samsung Find to locate a lost Ring. Unlike some competing devices, the Ring does not require a subscription. It comes with a charging case and will retail for $399. The Galaxy Watch Ultra competes with the Apple Watch Ultra. Extra durability includes a titanium "cushion" frame, Sapphire Crystal display, and 10ATM water resistance (plus IP68 and ocean swimming). In bright light, the display can reach a peak brightness of 3,000 nits. In an emergency, it can emit a loud Emergency Siren. In Power Saving mode, the 590 mAh battery can last up to 100 hours. A special performance cycling mode can calculate your personal FTP (functional threshold power) in just four minutes. It's also approved in the US for tracking ECG and sleep apnea. The Galaxy Watch Ultra starts at $649.
