I think this is on-topic. If not, I'll close the question.
I've seen at least one question, maybe more, on here about a Stack Exchange app for Windows Phone. However, to the best of my knowledge, there aren't any very nice ones. I'm currently working on a UWP app for the Stack Exchange network. However, it's my first time doing an app like this. I know at least several of the users on here are developers, and I thought perhaps some of you (some of whom I know are far more experienced than me) would be interested in working on it if I'd move it to GitHub?
If people are interested I'll move it over to GitHub. Otherwise I don't want to put it out there for the general public to get their grimy hands on. :)
Currently it's in a very, very basic state. It has read-only capabilities for all questions on Stack Exchange.
Anyway, to conclude, please let me know if you would be interested in helping with this.
UPDATE: I'm beginning to put the app into a very gradual closed beta. Let me know if you'd like to help test.
