Well, at least not much sense to me. At 100 bucks, you can get a blood-pressure meter. There's another company that makes one for 9. For another 0, you can get the iGrill, which is a meat thermometer that connects to your iDevice via Bluetooth. Then for 9, you can get a scale that connects to the internet via WiFi; you can use a web browser on any computer or an iOS app to read the results and charts, etc. It also computes bodyfat percentage and (if you program your height) BMI. Oh, these devices are, or soon will be, available for Android too.
