The app does work with Apple's Health app. You just open Health's settings and choose to import data from the Withings app. Unfortunately, the Blood Pressure display in Apple's app isn't much better — it has white data points on a gray background, and isn't very readable.
However, the $1 iBP Blood Pressure app can connect to your Withings account and download the same data. This app has a much better display, offering graphs with trend lines, timelines, and averages. You sign into your Withings account, them manually fetch the new data. You can then view the data in the iBP app, and easily export it in multiple formats, if you want to send it to your doctor.
With this wireless blood pressure monitor, you're certainly paying a premium for convenience, but it is much easier to use than standard devices. I'd have expected some sort of carrying case, as most blood pressure monitors provide, but there is nothing. If you don't mind the extra cost, you'll find that taking your blood pressure is less of a hassle. The confusing software drags it down a bit, but with the addition of the iBP Blood Pressure app, I find that it's a great solution to keeping track of an essential health metric.
