With Windows 10 now being a common OS and application platform across desktop, tablet and mobile, and with more and more people experimenting with Windows 10 Mobile or using it for real on a new Lumia 950/XL, it's not surprising that there's starting to be a steady flow of 'Universal' applications, coded to run across all form factors. The 'app gap' is starting to narrow, at least. As examples, in the last few days we've seen universal versions of Wall Street Journal, TeamViewer, and Tweet It!. To name but three. See the links and details below.

In each case, the applications are now rewritten to be universal, meaning that they run equally well on the phone, on a tablet or Windows 10 PC or (topically) under Continuum, plugging in a Lumia 950 or 950 XL, whereupon the application inherits the larger screen as if it were running on a full desktop. 'PC-like', as Tweet It! puts it.

The Wall Street Journal is a well known traditional financial news and analysis publication, of course. From the Store entry:

TeamViewer is a remote support application, whereby you can see what's on someone else's (typically) Windows PC screen in order to guide them through something. Think being called by your mum or dad to say that something's broken and then being able to guide them through the right things to click on, right on your phone screen. From the Store entry:

Provide spontaneous support for friends and family, or access applications on your home computer while on the go. The TeamViewer app allows you to accomplish all of this as if you were sitting right in front of the remote computer. Find out why more than 200 million users put their trust in TeamViewer!
