I ask myself every time I use my mobile (Android or IOS, I know windows phone has this default SharePoint app but not UX friendly) to open SharePoint site and feel why I should have mobile master and device channel settings to have good UX to navigate the site.
How an app that just works on any SharePoint site, just throw it a URL and display the site with better UX? Now you know what I’m talking about? Ok let’s list out the pros and cons
Pros:
•	Less Development for phones and tablets ( no need to design a separate master page, page layouts and device channel settings for mobile & tablets)
•	Better UX experience, of course it’s responsive
•	Documents upload/check-in/checkout made easy
•	Custom Search optimized for Phones and Tablets
•	Upload the elements like logo and fav icon to display (give option to select the elements for branding – sweet right )
•	Preview page ( like in design manager)
•	Simply deploy the solution file (farm level solution may be? Options are open)
•	Central administration link to maintain/support the application
Cons:
•	Performance (not sure you tell me)
•	Still thinking any ideas most welcome
Please comment your inputs, let’s see what we can come up with.
