Data Master for iPhone
We all spend a lot of time on the Internet at home and on the go. If you are accessing the Internet using your iPhone, you need to make sure you don’t consume more data than your wireless plan allows, unless you don’t mind paying overage fees. Data Master for iPhone is a powerful tool that keeps track of your cellular and WiFi data usage and takes the guesswork out of the process.
Data Master has a professional user interface. It shows you how much data you have spent so far. It should work with any service provider. You can set up custom counters to find out which apps are consuming more data than they should. The history graph shows usage for each day, which is nice. The app works in the background to monitor usage and notify you when you reach the limits you have set.
Data Master supports configurable billing periods and quota limits. The usage calculator is pretty helpful as it shows you what you can do based on your data plan’s limits. Overall, this is a pretty handy tool for those of you who want to avoid data overage fees. It will cost you just under $2.
