Obviously a game where you buy in-game currency can be arbitrarily expensive, and a subscription service can be as expensive as the length of the subscription. Don't include those. I'm looking for the biggest one-time cost, either to purchase an app initially or to "unlock" its full functionality.
There are several. 400$ (or 350€) is the most possible price that you can set for your app in Play Store now therefore no app can be nmore expensive than that.

As for the apps that have some real functions, there are Mobile Accessibility US and two different names with the same name: 5-Minute Sports Medicine and 5-Minute Sports Medicine. Each for about $100 or seventy-something euro.
And if you want to have the whole world in your Navigon navigation app it will cost you about $200 (or 160€ if you're in Europe).
