The windows 10 built in apps are terrible and not progressing at all compared to their counterparts on ios and Android. At this point why not just port the ipad apps to Windows and use them as the built in apps? It would save on development, bring higher quality apps to Windows and improve the ios bridge technology. It may even encourage other developers to port to Windows 10. I’m terms of look and feel I’d actually convert the ipad apps to a windows 10 fluent design like the one found on edge for ios.
Speaking of which has a single app ever been converter from ios to Windows 10?
