To use the Tanita scale, you have to own a specific Garmin watch, but not necessarily the best one. Also, the Tanita is very expensive compared to the Withings scale, and I'll rather be buying updated maps, etc. It's not like you need to make a deal with Withings; they publish their api.
Does anyone know a decent alternative to Garmin Connect that supports both activities from my Forerunner and Withings health data? I've had a couple of Forerunners over the past four years, and GC has been working great, though I'd like to have activities and health data on the same page, and it doesnt seem Garmin will add support for my Withings WIFI scale.
