emWave2 vs Instant Heart Rate by Azumio - an HRV Stress Check App for Android

I tested my #stress with Instant Heart Rate by Azumio simultaneously with the emWave2 and I found a decent correlation between my Coherence scores and stress and Azumio stress score. So based on the data below I do recommend downloading and trying the free HRV smartphone App. However, the major difference is that the emWave2 is an actual biofeedback device and it provides immediate feedback as to your HRV.
