Both the Qalo SL-1 and Garmin Cirqa wearables track heart rate, blood oxygen, skin temperature, HRV, stress, sleep stages and menstrual cycles without built-in GPS. The Cirqa offers more activity profiles and reliable automatic workout detection, while testers found the SL-1 failed to auto-detect activities despite Qalo's claims, though its battery lasted a week at 59 percent with no subscription fee.
A teardown of the Galaxy Fit 4 Manager app by SammyGuru has uncovered most of the tracker's planned features, including steps, heart rate, stress, sleep, blood oxygen and cycle tracking. The feature set closely mirrors the 2024 Galaxy Fit 3, with a tile-based interface supporting up to 12 tiles and a slightly taller display expected.
Apple recently launched AirPods 5, bringing active noise cancellation down to a lower price point than before. However, AirPods Pro 3 retain several features not found in the cheaper model, including in-ear tip design, built-in heart rate monitoring during workouts, and hearing health tools such as a hearing test, hearing aid function, and hearing protection.
Apple's new Watch Series 12 and Ultra 4 use a Health Sensing System that samples heart rate every five seconds instead of every five minutes, requiring the optical sensor's green light to flash almost continuously. To avoid that light being visible in dark settings, Theater Mode automatically slows heart rate readings back to five-minute intervals, but a new setting lets users override this and keep continuous measurements.
According to reports, Apple is working on improvements to the Apple Watch's heart-rate monitoring technology alongside a redesign of its Fitness and Health apps, expected to arrive with the Series 12 model. These changes aim to fix long-standing accuracy issues that have affected the device's health-tracking capabilities.
