We've been working on an NPC generator for a university Android course and we're finally at the point where we can share it with the world in the form of a beta test. The app supports English and Swedish, and currently works with phones running Android 7 and up. This is our first foray into Android development so there will be some jankiness, but you're free to try it out and if you want, send us a raven with your feedback!
