The tricky part is learning how to place your finger over you camera just right so that it gets a good read. There is a meter on the dashboard shaped like a heart and the closer to full it is the better your finger placement is which means a more accurate read! Once you press stop it displays your pulse, I am guessing it is an average of your pulse rates over the total time you checked it. I am sure it is not as accurate as an actual hospital machine but for a smart phone app it is pretty accurate. Of course the app itself displays a disclaimer that the app "is not a medical device" and you should "consult your physician" which I guess goes without saying... kind of... Either way I can use this to see if stress is making my heart race or if I have truly calmed down or what ever! Sometimes, for what ever reason, I feel like my heart is racing and with this I can check it out! At the least, it is just fun and worth checking out!
