When you put the Withings ScanWatch Wearable Heart Monitor on your wrist, you get access to so much information you didn’t know before. Because this wearable scans your heart 24/7, it will keep you apprised of your heart health at all times. It detects if your heart beats irregularly, and it can recognize atrial fibrillation. Not only does this wearable device alert you of your heart health, but it also tracks other aspects of your health. In fact, this smartwatch can recognize sleep apnea if you wear it throughout the night. Furthermore, it has a 30-day battery life, so it’ll last for a whole month before you have to think about recharging it. This heart rate tracker connects with your phone to notify you when you need it.
