BENIO Gen4 Smart Ring: Health monitoring with heart rate and blood oxygen
The Benio Gen4 Smart Ring is for anyone who wants to keep an eye on their health without wearing a bulky watch. It's perfect for tracking your sleep and daily activity, whether you're at the gym or at your desk.
Instead of just listing heart rate and blood oxygen, think of this ring as a wellness partner. It checks your heart rate and blood oxygen every 30 minutes automatically. You don't have to remember to start a session. It also tracks your sleep stages—deep, light, REM—and wakefulness. You get a clear picture of your sleep quality in the app each morning.
The ring is slim and lightweight. You'll forget you're wearing it. It's water-resistant, so you can keep it on while washing your hands or working out. No subscription fees mean you own your data completely. The app gives you daily reports and trends. You can tweak your habits based on real numbers. The motion alerts pop up before you even think about checking your stats. This ring helps you connect with your own health in a simple, direct way.
