If you are interested in the use of Internet traffic and have an iPhone or iPad with iOS jailbreak, you can try a new jailbreak tweak called NtSpeed, which keeps updated real - time traffic speed Internet.
Once installed, the tweak shows a small bubble just below the battery indicator in the navigation bar of any application.
The tweak shows both upload and download data, so this information will give you an idea of the total amount of traffic you are using.
You'll notice that the information is updated in real time while surfing the web, because it has access to Internet - based applications, so the device will not be using your internet data without your knowledge.
In most applications, the flag does not interfere with anything, but sometimes in Safari, it will appear just above the refresh button in the URL bar. Fortunately, this does not really interfere with your ability to tap into it and type in the URL bar.
The moment you scroll down you will not look so uncomfortable as it blends very well with the navigation bar.
The appearance depends on the application. Many of the applications have a nice white space where the bubble appears while some have some type of icon or button at that exact point. In those applications where a button is located in the same place, the bubble does not interfere with its ability to interact with it.
There is no option to configure, so after installing the tweak, it will start working immediately.
You can download free from the repository NtSpeed ModMyi Cydia on any device jailbroken iOS 7, 8 or 9.
