Data Usage Monitor is a new tweak recently published in Cydia that allows iDevice owners to check in real time the data traffic made from their own terminals. The tweak displays in the status bar a counter in KB/MB for the data traffic you do and while you surf the Internet or use applications you will notice how the traffic is done. The tweak allows you to view download/upload statistics for both Personal HotSpot sessions and your sessions, so you will always know if any application or user is using your data connection.
Statusbar indicator when downloading over data! This tweak is a money-saver! It allows you to monitor the cellular data traffic, live on your status bar.
While you browse in any networking application such as safari, facebook, youtube, twitter etc. You can watch the data bandwidth usage right on your statusbar, ensuring you won't exceed your data plan's limit, plus knowing what an application actually downloads in MBs. It also shows live data usage for Personal Hotspot clients! Customizations allow you to set what should be shown in real time. You can also specify a bandwidth limit in MB so you will be notified if you exceed it. It adds a bonus LIFETIME data usage statistics in its settings.
