By J Keirn-Swanson One of the best things about the iOS Health app is just how much data it collects in one place. With deep nutrition metrics, lab results, body measurements, fitness, and sleep data, this virtual file cabinet keeps everything organized. In our previous articles, we’ve shown what the Health app can do by itself and with additional apps, but if you’re really serious about monitoring your health, you might want to take things to the next level and invest in a wearable or other additional device.Sure, you could weigh yourself every day and enter that data manually. You could write down the time you fall asleep and the time you wake up. You could hope that the 10-year-old treadmills at your gym give a reasonably good estimate of your workout. You could use the free blood pressure cuff in the drug store and enter that information manually.Or you could pick up one (or more) of these cool gadgets. We spent weeks wearing fitness trackers, monitoring our heart rate and blood pressure, and even took devices to bed with us, all to capture as much health data as possible. Here are our findings: 11 devices, compatible with the iOS Health app, that you can count on to take fitness monitoring to the next level.
