While there are a number of websites that enable you track the chart positions of games and apps, they tend to be heavily US-centric and a little clunky.

Design agency and developer ustwo has come up with a different way of presenting the information however with PositionApp.

Just released onto the App Store, it enables you to track the performance of any app in the top 300 free or paid charts in any country.

Using six months of data, you can browse by app name, country, genre, position change, free or paid status, or by changes over day, week or month.

You can also select favourite apps, which are displayed on your personal dashboard, as well as sharing any top 300 app charting data, and buy any of the apps.

"Successful app development is as much about marketing and PR as it is about the concept and creation," says mills, co-founder of ustwo.

"As app developers, we wanted to understand our sales volume, gauge the penetration of our marketing strategies and easily follow the success of the app once it leaves the nest. We created PositionApp because as developers we wanted, and more importantly needed this app.

"PositionApp was created for developers, marketers, journalists and reviewers, but by adding a revolutionary set of app discovery dashboards highlighting the biggest app risers in the top 100 and top 300, the app will be appreciated by just about any app user."
PositionApp will be free for two months, thanks to a deal with AdMob, so best get it now. [App Store link]
