The app is not up to date, and it throws a bunch of errors when you try to run it or doesn't run at all! I got to run it once by manually updating it through npm, but after the latest expo update it just doesn't work again! Really hard to customize! There is a lot of code and I just can't follow how it's all linked. They provide some instructions on how to customize their app, but it was not helpful for me cause again with the latest update it doesn't run through a simulator.
