Khan Academy app launched with Windows 8 last October. A few of us worked together to get the first version developed just in time for Windows 8 launch. Since then, there have been a few minor updates and a big overhaul which was published in store last month. This week is another great milestone: the app is now open source and ready for anyone to contribute.
How We Got Here
I developed the initial version with a lot of help from folks over at Khan Academy and an internal Microsoft team. It was really a port of Learning Circle phone app to Windows 8 so naturally, this was developed using C# and XAML.
