In just few seconds I could create new pages in my WordPress site with custom meta data like title, slug and tags right from the front-end editor inside the application itself! It's very good way to collaborate without creating any back end code.
The only downside is that you need an internet connection to setup your website/blog as backend server or else it will not work. If you have one than go ahead otherwise wait till they launch offline mode which would be awesome!! We are using this tool mainly for our client portfolio section where we give them access via web browser but also can edit it directly through app if needed.
