My Data Manager is a tool that lets you keep full control over your mobile phone's data plan so that you don't go over the limit on your contract, don’t pay extra charges ever again.
The first thing you'll see when you open the app is a message that prompts you to create a data plan that fits in with the plan on your contract. So basically, if you have a data plan with a 500 MB monthly limit, you’ll have to write in 500; if it’s 300 MB, then 300. It’s that easy.
Once you've done this, you'll go on to the really interesting part of the app, the one that gives you a detailed visual report of each one of your apps’ MB consumption, listed from the ones that consumed the most to the ones that consumed the least. You can thus see exactly which apps are draining away all of your mobile data.
As if this wasn’t enough already, you'll also be able to see graphs with historical app data usage, letting you see during what weeks or months you consumed more or less data.
My Data Manager is a very useful app for users with data plans, as it lets you know what your MB's are being used in at all times so that you don’t go over your limit.
