Review on 📱 Wellue DUOEK-S Bluetooth Heart Monitoring Device, Free App iOS Android & Tablet Compatible, for Home Use - Enhanced SEO by Rodney Harris

It's simple. There were no complex applications to learn. My Wellue DuoEK-S monitor has worked flawlessly from the start. The new screen model has several useful features. When you place your fingers on it, the screen will tell the time and "stay where you are". Your heart rate and pulse rate will then be displayed. It alerts you when you've reached 30 seconds, the minimum time for recording on your smartphone. When you remove your fingers, either a "normal" or "irregular" heart rate is displayed.
