That's really interesting to know, your app looks awesome. May I ask how long that took you and did you make this in JS? I'll try raising the price of mine for a week and see what the results are thanks. Link to Blu Graing Calc: http://apps.microsoft.com/webpdp/en-us/app/blu-graphing-calc...
Thanks :). This was around 7 months of mornings and weekends while I had a full-time job. (I quit a month ago to start my own thing). I built this with JS/HTML/CSS but the MathEngine component I built using C# (.winmd) and called into it from the Javascript. If you have any specific questions about how different parts are implemented, let me know :).
I was just thinking that with the state of the how APIs were last year this would have been very tough to do, so I was wondering if you went the JS route since it was in better shape than XAML.
