Richard Walters is the developer of Calculator² and Calculator³. You may have used these apps before on Windows 8 or Windows Phone - we've taken a look at the mobile app in the past. It's been announced today that Walters has been able to accumulate over 1 million downloads on Windows Store for his Calculator² app alone.
Entering the DreamSpark program as a student, Walters received a Windows Phone and his journey began. What makes this story that much more unique is Walters doesn't have a development background. In fact, Calculator² was his first app ever developed, released on Windows Phone.
