Congratulations to UK developer ustwo, which has announced its various games and apps have been downloaded over 500,000 times.

Actually, I need to be a bit more precise.

When I say 'its games and apps', that should be the games and apps it's developed and published itself, as it's been pretty successful working with big brands such as Reebok and Cartoon Networks' Ben10.

So just to make clear the 523,000 download total, as of Monday morning, doesn't include those big brand games and apps.

Most recently, ustwo has released the excellent - and still free - PositionApp, which lets you see the position of the top 300 apps in any country with an Apple App Store store.

To-date, it's been downloaded 165,000 times.
