I don't know what all the windoze app does do, so I am not sure what would be missing in the Android App. I do think that the Android App is not as fully functional but any missing functionality could be added over time. The author does update the app from time to time. But the Android App does what I need to do...installing and extracting tunes, and adjusting a few things. I can assure you I am violently and thoroughly opposed to Microsoft and am willing to do without some functionality to avoid using a Microsoft product...it just ain't knowingly going to happen.
