Hi guys, after many weeks trying to install a paid app , i got sucess.


The app is HRV4Training( HRV4 is the first validated app able to measure your Heart Rate and Heart Rate Variability reliably, without requiring any sensor.) The only scientifically validated HRV app that doesn't require an external sensor. HRV4Training helps you optimize your goals and prevent overtraining by measuring your Heart Rate Variability and providing tailored feedback on your physical condition. HRV4Training does not require a heart rate monitor, since it can accurately assess your HRV using the phone's camera.

The app loads my data ... but when i use the cam + flash light to read the Heart Rate Variability ..the cam burns my finger and also the value is inconsistent. My device is a Sony xperia x f5121 and i have never problem with the app ( Android OS) I guess the problem is just an adjust. Any idea? Thanks in advance
