Inaccurate!!!!!!!!!!

Best Ive Found

I have tried many data usage apps and this is the one Im keeping. It, by far provides the most accurate measurements.

Stuck in setup

Just purchased and stuck in setup. Entered "billing day" and cant move on.

Cannot complete setup

As soon as I try to enter data into the set up page, the save block at the top goes away. Once in the app I cannot find a way to return to set up. The app is useless without being able to enter my personal information.

Not working!!!

This app is so bad , doesnt calculate the usage and gives wrong number of data usage !!! First Its jumped from 20% to 46% and down to 9% !!!
