How to Track Your Heart Rate With Only Your Smartphone

The article from CNET discusses various methods to track your heart rate using a smartphone. It highlights that while smartphones themselves do not have built-in heart rate sensors, there are several apps and accessories that can help measure your heart rate. One method involves using the smartphone's camera and flash; apps like Instant Heart Rate use the camera to detect changes in blood flow through your fingertip. Another approach is through smartwatches or fitness trackers that connect to your phone via Bluetooth, like those from Apple, Samsung, or Fitbit, which have built-in heart rate monitors. Additionally, there are external devices like chest straps that can pair with your phone to provide heart rate data. The article also mentions that while these methods can be convenient, they might not be as accurate as medical-grade equipment, and it's important to use them as part of a broader health monitoring strategy rather than for medical diagnosis.
