Withings is a company that has wi-fi enabled devices. These devices include apps and all kinds of smart-enabled tools (including ifttt.com integration.) Scales can automatically log your weight to evernote or a google doc to track, a blood pressure monitor and perhaps my favorite, a baby monitor that lets you dial in on junior using your iphone or ipad. (I needed that when my children were younger.) I am thinking about getting the baby monitor to use to monitor my classroom. So many different applications.
