Thanks for your email. We would like to bring Stitcher to Windows Phone, it’s just a matter of time and resources as we are still a small company. We are also working on an html5-based version of the app that could be used on Windows Phone and other platforms so potentially, that could be an option for you. We understand you may prefer a native app and that’s likely where we’d want to go eventually. We’ll keep you guys in mind as we get closer to heading down that path!
In the meantime, Stitcher does have a web app that can be accessed online at http://app.stitcher.com/ as a possible alternative and we are working to build a mobile optimized version of the Stitcher web app – so please stay tuned!
