While it is accurate (I work in a hospital) it also does have a glitch where it can take the pulse of a table if left laying down while running the app. Disappointed!
I like the improvements and the stress measurement. It works great!
Allows me to monitor my pulse.
Died at launch. Nothing shows. Just the error dialog. Used to like this. Now useless.
Updated crashes only. Older version works but it's algorithm is error prone. It does not even try to distinguish between the noise and real heart beat so if you do not precisely operate the camera, it measures frequency of any picture change which is why so many ppl say it measures heart rate of a carpet or similar. To be rewritten, but a nice start.
Most Precise Heart Rate Monitor Ever + Unlimited Measurements and Records.
