It does what it says it does. Put your finger over the camera and the light and it takes your pulse.
I would much prefer if it allowed some basic filtering -- for example Id like to show only readings from the morning, or only exercise readings, or a few others combos (particular time frames, mainly).
Overall a nice app. I use it frequently to keep tabs on what my heart is doing.
