When Apple introduced iOS 4 one of the things they opened the door to was more device connectivity. Withings is delivering on the promise with an iOS connected Blood Pressure Monitor (read my review of the hardware here). The App doesn't really do you any good without the Withings devices. However, now with either the Withings WiFi Scale or their Blood Pressure Monitor you can use your iPhone, iPad or iPod touch to track your progress. With the Blood Pressure Monitor (BPM) in particular your iOS device serves as the display. The BMP connects directly to the dock connector on your iDevice and you control it from the the touch screen. Once the reading has been taken your iDevice transmits the results to your free Withings account. You can even email the results to your doctor.
While the App works well there is a little room for improvement. First off on the iPad in particular the graphs don't seem to be as optimized for the larger iPad display as they could be. In some cases I've even see seen the lines disappear as if they are too thin to display. I'd also like to see some more sharing options besides just emailing the blood pressure info or sharing weighings with other Withings users I'd like to have my weight automatically emailed to my health coach each time I weigh myself. That is certainly not rocket science and very doable either from the online account or from the iOS App. Other than that if you have the budget for the devices, they are a fun way to track your weight and blood pressure. It's nice that the App doesn't have to talk directly to the scale. This way you can just weigh yourself without having to first look for your iDevice. The App is sync'd with your account online and shows a push notification once a new reading is available. Nicely done.
