We have a AT&T data share(family)plan.Last month(Oct 2014), we were charged $15 for 8 MB dataoverage. sodepressed, I started to look for an app that could
1. monitor family data usage
2. tells me if I am over scheduled usage so that I can limitmyusage early in a billing cycle.

My AT&T is good but it requires log-in each time. Otherusagemonitors are great except they just monitor single device'sdatausage than the family plan's.

So here is this little app that helps me. I hope you findithelps you, too.
