Use your LED flash and Camera for Heart Rate monitoring


Yes, it is possible to monitor your pulse rate without the use of any fitness tracker or devices with a dedicated heart rate monitor.

 At once, it might seem like a gimmick or joke for you but it does actually work to a certain extent.

Now, there are many apps available which let you track your pulse rate.

 The ones which actually work require your finger to be placed on the LED flash after which the app uses the camera to track color changes under your skin to monitor the amount of blood passing through.

Given that this is software dependent, don’t expect much accuracy and make sure that the LED flash on your phone doesn’t reside too far from the camera lens. 

Also, use a good application for the same as the Instant Heart Rate app which we have used here for best results.
