CellMapper[0] is not real-time, but it collects data to make sector maps and estimates the position of the current eNB. Users who contribute enough data can "pin" these eNBs in the correct location.
Despite not being real-time, it's the best / most accurate app I've found of its kind and has a good community behind it.
