The flashlight burns your finger before it finishes the reading. It takes too long to finish the reading. The flashlight even the phone has a message under the highest setting that says to avoid contact with skin as it will cause burning. Turning down the brightness of the flashlight, does not also correspond with the brightness of the app. The app will be at the highest light setting, therefore causing the burn. Good idea though, as previous generation Galaxy phones had the BPM monitor on them.

the app wouldn't go any further than me placing my finger on the camera and flash light...I did it the correct way, and held it that way for a good amount of time. I could see my heartbeat, but the screen never changed or said anything else. I started over and the same thing happened. so eventually I got sick of trying and deleted the app. I just wanted to see if it works. I have AFib and have had 2 heart surgeries. but I guess my heart was too much for the app!

When using it on something that does not have fingerprint recognition or a button, the app will tell you to place your finger on the flash with it on, which burns your finger, very painful. I would recommend just checking your pulse and counting them, or buying a smartwatch if you can afford one.
