Accurate – Data Cellular Counter Pro ( monitor data usage ) Review
I have dataman next as well installed but it's not at all accurate. I'm not sure if it's because I have the Onavo Extend activated in there or what. But this app works as advertised with +-1MB error margin for me.
The interface is not as good as dataman next though.
