Google sees an opportunity with fitness and, like Apple before it, the company is building a service to help the growing list of wearable devices talk to one another. Dubbed Google Fit, Google said its new platform will help users keep track of their fitness goals across various platforms and wearables. "Fit takes away the complexity of handling multiple sources," said Ellie Powers, product manager at Google Play. She said the new service, with consent, will give developers access to a big stream of information about a user's health details. "This helps you create more comprehensive apps." The service follows in the footsteps of HealthKit, a service from Apple that basically attempts to do the same thing. During that product's unveiling earlier this month, Apple said it designed its service to track all manner of information, from fitness goals to health details.
