What’s the most accurate data usage app?

As the title says, I am looking for the most accurate data usage app, preferably one that can give regular notifications.

Thanks

The most accurate is the one your carrier provides. For third party apps Dataman is pretty good.

Yes I use DataMan Pro, but it’s a little off.

You won't find anything that's completely accurate but in reality your carrier should notify you anyway if you totally max your plan out / get close. If their app sucks you can just use a reasonably accurate third party app for the day to day and it won't be too bad.
