Best iphone data usage app

[Sigma721]

Hi

I am looking for an iphone app that shows the usage for each app. Does anyone know of one?

I am currently using data usage pro which only shows usage per day.

Thanks in advance

Also check out onavo, it also reduces data usage over cellular

Settings -> General -> Usage there is a counter for mobile usage.
