Who created the step app?

I'm curious to know, who was the visionary behind the creation of the Step app? Was it a solo entrepreneur with a passion for fitness and technology, or perhaps a team of developers who saw a gap in the market for a more engaging and motivating way to track daily steps? I'm intrigued by the origins of this innovative app and would love to learn more about the individual or group that brought this concept to life. Was it a result of personal experience, market research, or perhaps a combination of both? I'm eager to gain insight into the story behind the Step app and understand the driving force behind its creation.
