I reviewed the Withings original WiFi Body Scale back in 2010 and have been using it almost daily ever since. I like how it records my weight so that I can see trends using my Android smartphone or iOS device. Withings has recently announced a new model called the Smart Body Analyzer. Priced at $149.99, this new scale still features WiFi data uploading of weight and fat mass, but it also records your heart rate and air quality. Your heart rate is recorded through your feet, so you don’t have to do anything special like wear a strap. Just stand there for a few seconds and your resting rate will be recorded, which can help you track your fitness level. Indoor air quality through temperature and carbon dioxide measurements are also recoded, which can help you know if your CO2 is at a healthy level.
