New Zealand-based developer Bluespark has come up with a very simple and great idea - a heart rate monitor for the iPhone.
The app works with the built-in microphone on the iPhone 3G (older versions have to use the headphone cable mic) to listen and detect heart beats. The user simply holds the iPhone either directly over the heart or on the pulse in either neck or wrist to determine the heart rate.
The interface of Heart Monitor is very well designed and for anyone who would use a heart rate monitor anyway, the price tag of $4.99 seems fairly reasonable. A great app for anyone who works out a lot, wishes to keep track of their heart rate or for pregnant women who need to watch their heart rate when exercising. Although this is a great app, our rating is a 7/10, since it is hard to truly establish the accuracy of its performance, taking both the microphone and its positioning into account.
