Best innovative feature of MWC 2014: built-in heart rate monitor on the Galaxy S5

We've reached a state where delivering an innovative feature or functionality on a smartphone has become extremely challenging, and manufacturers are investing lots of time and resources into developing the technologies that could make their products stand out. Not all of these innovations, however, go beyond being flashy gimmicks. That heart rate monitor built into the Galaxy S5, on the other hand, is something worth looking forward to.

With its ability to check one's pulse, the Samsung Galaxy S5 could be more than just a great smartphone. It becomes your personal health monitoring tool, thus helping people stay fit and well. Furthermore, the handset is able to act as your fitness assistant, working hand in hand with the pre-loaded S Health 3.0 application. And now that the S Health SDK is available to Samsung's software developer partners, who knows what else the innovative sensor would be used for in the near future.
