I'm looking for an Android application that can show the network usage history over the past 12 hours. I want to see the graph of the upload and download usage over the past 12 hours (or more). It should be able to plot even if the app does not have the focus, i.e. is not in the foreground, i.e. is in the background. Any license or price is fine.
I tried Network Speed - Speed Meter but it only plots when the app has the focus.
