Unless I'm missing something obvious, the Wikipedia app is violating the rights of Wikipedia contributors -- there does not appear to be any way to view the contribution history of an article.
A quick/easy way to resolve the legal issue might be to include a http link to the history tab that pulls up a web browser. But I would think an app produced by Wikimedia should aim higher than that, and include a native viewer for the article history, to more genuinely honor the contributions of an article's authors.
