Review: Piny UWP (Pinterest)
(All About Windows Phone)

It`s been a week of major service UWP applications, though not from first parties - we`re talking thrid party here (mainly Chococode) - but don`t let that put you off. If YouTube, Tumblr, Flickr and - here - Pinterest don`t think it`s worth producing their web content in Windows 10 UWP app form then here at least is a great third party alternative.
