Google and personal health data have a rocky past. That includes a unified medical record service called Google Health that the company shut down less than four years after its launch. Now, with a rise of wearable devices — including upcoming ones running Android Wear — Google wants to offer a way to collect and organize the activity data. Thats according to Forbes, which says Google will unveil a new service called Google Fit at its annual developer conference, which begins June 25th.
