It seems like there's a new digital health device announced every day. Last week alone, Melon finished a Kickstarter campaign for a wearable head band to track concentration and potentially sleep, Basis launched a mobile app to accompany its Basis Band and Glooko relaunched its mobile diabetes management device. Still, in an increasingly competitive market, a few digital health devices have gotten physical shelf space at some big name, big box, technology and retail pharmacy stores.

The MobiHealthNews team checked out local stores in the Boston area to see which of them carried digital health devices. Although this isn't a wholly comprehensive list of which digital health devices are in stores today, we think it serves as a helpful snapshot.

Read on to find out which stores had the most devices and what we found most often on store shelves.

Best Buy

By far, Best Buy had the largest collection of digital health devices, a likely effect of Best Buy's 2010 initiative to add mobile health, narrowly beating out the Apple Store. Fitbit Flex, a wearable activity tracker, was sold out at almost every store we went to and Best Buy was no exception. Some lesser known devices in the fitness and health section included Pear, a smart coaching device system (although it was out of stock), and Scosche Rhythm, an pulse monitoring armband. Displayed at the front of the store, large Fitbit and Jawbone displays bookended the shelves that held the other fitness products. Fitbit Zip tracks activity, while Fitbit One tracks activity and sleep. The Fitbit Aria WiFi Smart Scale tracks weight, body fat percentage and BMI. Other wearable activity trackers included BodyMedia Fit Link Armband, Jawbone UP, iHealth Wireless Activity and Sleep Monitor and Polar FT4. iHealth Wireless Body Analysis scale and Withings Smart Body Analyzer are wireless weight scales for adults, while Withings Smart Kid Scale monitors a child's growth. iHealth's Blood Pressure Wrist Monitor tracks and saves blood pressure data.
