Disclaimer: I wrote the Android app that would speak to that meter last year. It did blood glucose AND blood pressure and would transmit the data (via a companion app) to Google Health (until they killed Google Health. Sigh.)
That is a fine device, but not really portable. The challenge we had designing the iBGStar was making a credible glucose meter that was affordable and also tiny. It was a real team effort between our ID, UI, and HW engineering teams to make a fully functional, medical grade tool that also fit nicely with the portable phone form.
