Editor’s Note on 7/29/2010: PlanHawk was not available on the iTunes App Store for a short while, but it’s back and better than ever according to the developers at Kidoc.

On Thursday, July 22, Kidoc LLC announced an exciting new product for iPhone iOS4 users: PlanHawk.

This mobile app fixes a serious problem many iPhone users face on a monthly basis: Exceeding their data plan coverage.

With the new AT&T capped data plans, users face the problem of going over their limit, and being charged excessive fees. PlanHawk’s $.99 application monitors the phone’s data usage, allowing people to avoid steep charges.

This application is especially useful to iPhone 4 users, who now can use HD video and stream rich media. These new features eat up data at an alarming rate, and could force you way over your limit very quickly without you knowing.

And honestly, do you really know how much data certain applications and functions take up? There is no sign that says, “HD video will use 25 MB in 30 minutes.”

This is where PlanHawk can help you start to understand what takes up data. (more…)
