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.
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.
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.
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.
Please fix this problem because this could be the best photo based hrv app! The range for hrv score says it is on a 0 to 100 scale but mine ranges from 900 to 1225. So it's like a different scale but with arbitrary units and no comparative reference I can't know what this means. And stress index range is 1 to 1000 but I havnt seen any numbers over 100 so i don't know if this number is right either.
