Does not detect pulse accurately. Shows wide variations that do not exist. HRV over 1000! and other numbers that are obviously wrong. Default app that came with my phone tracks heartrate much more accurately.
GREAT! 1 FIX NEEDED works great! FOR THE DEVELOPERS: when detecting pulse with the camera if you would just allow to 'cut' at the start and finish of the graph that shows in the end of a 1 minute session. Its always wrong at start and at the end, even if i keep the finger on the camera and run more than 1 minute sessions in a raw not changing the light pressure of the finger. The start and finish errors compromise all the stats at the end! :S
This app is almost useful because it tries to look at heart rate interval. Nice try but it just doesn't work and there's a screen with stats that are re totally meaningless. It would be nice to be able to look at the graph and scroll through the detail but it doesn't seem like there's any way.
Excellent. One of the only apps that offers monitoring over a longer time (60 seconds) and saves a neat little graph. Consider the option for a beep sound whenever a heartbeat is detected.
has potential app looks great, but with hrv it's important to be accurate. it would be great if it could crop or remove the spikes (mostly at the first second)
Awesome photometry HRV It's hard to find apps which give good HRV stats that don't require a bluetooth pulse monitor. This uses pulse photometry using the camera and led light, and gives me the data I want.
