Heart Rate Monitor (appstore) (Read 34 times)

Hi. My fitness tracker does not have a heart rate monitor (instead, I opted for a long battery life). I am looking for one in my cell's android app store. However, every single one I tried, for whatever reason, turns on my phone's camera flash. Is there any app I can use which does not turn on the flash? Because that annoys me to no end, and can literally burn the skin.

My old Samsung (which is literally dead now) had an app that did not turn on the flash. Unfortunately, that app was proprietary to Samsung, but at the very least, I know it exists.
