Test your geographical knowledge in iPhone and iPad puzzler GeoBrain

Perhaps best explained as a mash up between Google Earth and a trivia geography test, GeoBrain is one of those iOS downloads that sits somewhere between apps and games.

Created by German map-based developer skobbler, it has you working your way through hundreds of geography, history and entertainment questions.

Starting with the selection of the correct continent, you have to further display your knowledge in terms of the location of countries and individual cities.

Using a Google Earth-style interface, you can pinch to zoom in for detail, with the three difficulty levels providing you with various hints in terms of country borders, rivers and cities.

Still, if you're anything like me, you'll probably be embarrassed by your failure to pinpoint fairly easy places - in my case Munich and Kiev, let alone the likes of Kinshasa and Thimphu.

There are three modes - Standard, Arcade (which is speed-based), and Distance. You get points for the correct selection of continents and countries, and there's a sliding scale depending on how close you get to the required city.

You can also use a joker to double up your points, and there's a Wikipedia link out button if you want to know more about the current topic.

Surprisingly though, high scores are only saved locally so you can't yet compare with other players. Presumably some sort of online mode will be added in future as the questions are also updated. You can never have too many questions.

GeoBrain is available as a universal app for iPhone and iPad, priced 59p or €0.79.

At the moment it's only available on the European App Store, but a US release is planned soon.
