The next frontier in mobile technology clearly centers around wearables and health and fitness as tech companies are looking to one-up each other with applications in this space. The most recent, Google Fit, is Google’s forthcoming “health aggregator” designed to sync personal statistics and data in the cloud and Android devices.

Google Fit will debut at Google’s I/O conference for developers held June 25 and 25, according to Forbes. It is not known whether it will be a standalone app or be built into the next Android version. It will aggregate data through open APIs, “instruction sets that allow apps to share information,” Forbes reported.

“If the next version of Android comes out with a version of Google Fit, top vendor Samsung could simply re-engineer the open-source platform and replace Google Fit with its own health platform, Sami,” Forbes added.

According to Forbes’s Ewan Spence, Google Fit has been in the works for some time and is not a direct response to Apple’s HealthKit, announced at the WWDC in May. Samsung’s Sami is also an offering in the same vein, with the premise of all of the applications being a user’s ability to track their health and fitness.

With smartphones hardly differentiated by hardware or appearance any more, Spence writes that software is key in winning over consumers, and it’s “not just in the apps available or how easy the built-in apps are to use, but the software that will have a memorable real world impact on the user.”

It’s unlikely that Apple HealthKit and Google Fit will be used interchangeably, meaning users will likely have to choose one or other, according to Spence. “If you start off using the Google Fit system, you are more likely to stay with that service as you upgrade your smartphone,” he writes.

Data safeguarding is a major issue as privacy concerns are the forefront for consumers and Google Fit and HealthKit success hinges on how secure the systems are in protection personal health data. In both platforms, users will be uploading various information about their health.
