I have seen the MUSE app for UWP at Windows Store. I believe that it is compiled using visual studio C++. I also believe that it should be possible to compile that for ARM for Windows 10 Mobile and the Up Coming Windows 10 am ARM ( Q4 2017).
Windows 10 on ARM will provide "Always connected" new possibility to explore new business models using MUSE. I strongly recommend that your development team spent a few days just to configure the VISUAL STUDIO C++ environment for ARM (Windows 10 Mobile). With that, the Same MUSE app in the Windows Store can be made available to Windows Mobile users.
