✔ Custom counters can be setup allow you to monitor usage during a certain period to help identify data hogging apps. Counters can be easily enabled or disabled and can even be configured to end at a predetermined time.

Pros and cons of Data Master - Monitor Cellular & Wifi Data Usage app for iPhone and iPad

Data Master - Monitor Cellular & Wifi Data Usage app good for

Only One Thing: you should Write that the Projected Volume is Not just a simple average of the past Volume multiples by the Rest of the month, but rather an Extrapolation of the Future, which Takes in Account your inversed/ decreased usage.

Im using this daily to keep track of my data plan and wifi usage. Now I know when I can go on a download binge before my billing cycle restarts.

I have checking my usage with my carrier. & with this app & the app is almost dead on. Works great. & you dont need to run location servicing with this app. So it doesnt drain your battery.

Love that it keeps me on track and also allows me to get close to my limits

Yes, this app definitely has trouble resetting itself at the end of your monthly billing cycle. I always have to reset this app, reboot my iPhone & reset this app a second time. Sometimes other bugs pop up too. Otherwise, this app is useful.

Some bad moments

Was good until last update. Now its all over the place and not accurate.

It was a good app but after last update is so bad, it goes from 95% back to 83% then 80% and start counting again Not accurate anymore.

This was a great app to track cell and wifi use. Then I rebooted my iPhone and the data use went back to zero. That is poor design.

Im guessing that I am given the data I need however we cant see what was used and when the chart is too small and doesnt break down usage per day. As a result I cant pin point when I used unusual amount of bandwidth.

The data monitor is a better app. Data master seems to have issues trying to reset on month ends.

Cannot get out of first setup screen except by closing app. I want my money back!
