A bit disapointed ..
What i expect from such an app is to give me some data, what is the spread compared to what should it be in the books, what is the heart rate, store the graph with the result, visualize the "stress control" by seeing the rate decreasing ... But nothing of this is present. Technically, doing this app in html5 doesnt seems to be a good idea seeing the result.
Good idea, but approximate realization
