Like millions of people, I need to keep an eye on my blood pressure. You can check it when you visit your doctor, but many people have "white-coat hypertension." Just getting their blood pressure measured at the doctor's office stresses them out, resulting in higher than normal readings. All the better reason to check it at home.
A regular arm-worn blood pressure monitor is around $50. So at $130, the Withings Wireless Blood Pressure Monitor isn't competing on price, but rather convenience. Saving money doesn't matter if you don't wind up using the device, and Withings' version makes checking your blood pressure a lot easier.
Using the monitor
Withings had originally offered a wired blood pressure monitor: it connected to an iOS device's 30-pin dock connector. You can still find some of these for sale, but if you have an iOS device with a Lightning connector, you'd need an adapter. The new wireless model uses Bluetooth, making it a cinch to use, and also offering Android compatibility.
The device is bulky, with an aluminum tube that contains the hardware to pump up the cuff and the batteries, which is attached to the cuff itself. It's an all-in-one device, with no tube connecting the hardware to the cuff. The cuff is rigid, and you have to pry it open a bit to get it around your arm; you then attach it with velcro and it's ready to go.
To take measurements, you first press a button on the blood pressure monitor, which wakes it up and launches the Withings' Health Mate app on your iOS device. Then tap Start to have the cuff inflate and begin measuring your blood pressure. When it's finished, readings display in the app: systolic and diastolic blood pressure, and your pulse.
Some doctors recommend taking three measurements and averaging this; Withings calls this Automatic Mode, and you can turn this on in the settings when the Health Mate app is waiting for you to tap Start. But this setting doesn't stay enabled. As the Help materials explain, "According to a requirement from the Food and Drug Administration, you need to enable this setting each time you want to use the automatic mode."
I found the device to be a bit finicky at first. I got measurement errors and had to restart. The cuff seems more sensitive to exact positioning than other devices I've used, but once I got the hang of positioning it, it worked fine.
Viewing your data
As for the Health Mate app, I find it confusing at best. Its display isn't very intuitive, its Dashboard view shows the last reading and a vague graph, and its Timeline shows graphics that seem to have no relationship to your history.
