Here's 'Perfect 9GAG' in action:

Browsing 9GAG jokes and memes; (right) the hamburger menu lets you go the section you're interested in, plus various account options...

Most gags are static images, but animated GIFs are also popular; (right) it's easy to make your own 9GAG joke or meme too, within the application...

Just pick a meme image and add your own custom joke text...

You can grab Perfect 9GAG here in the Store. It's free, too, so download and enjoy. Being a UWP app, this will also work on your Windows 10 tablet and laptop/desktop. And probably via Continuum, though I haven't tried it (yet).
