According to craziestgadgets ”you can use this iPhone Blood Pressure Monitor to check your blood pressure and display the results on the screen. The screen displays systolic, diastolic, and pulse readings and allows you to store a time and date-stamped history of your readings. If you need to take regular blood pressure readings, this is a convenient and useful way to both get and track your readings. The dock will give you 100 tests per charge up, so it can travel with you too. Compatible with all iPhones, iPads and most iPod Touches. $99 from Hammacher”.
