Hi, I'm finding it a little hard to calculate data usage vs time left on my plan. its difficult because of the 90 day terms vs a 30 day. I would love to see a pie chart showing, data usage and time reamining till next renewal.
Although it is a nice idea for some sort of graphical display, can you use a calculator to figure out the percentage remaining (used / allowed amount), and then compare it to the number of days remaining? It's simple math.
There are apps for that. I use "My Data Manager" on Android. 90-day cycles are thankfully an option, and it has pie charts too. It also can handily display your data usage in the notification shade, shows per-app data usage, and notifies you when you've hit your daily usage quota (based on data remaining divided by days remaining). Super useful!
