London Bus Tracker Unique

Here is a screenshot of a London bus app for iOS I have developed. It shows the a nearby map with bus stop location. In London, I have come to appreciate its advancement in stop information. Every stop is assigned a letter for passengers to easily identify the bus stop. Most of the bus stops are closely located. A simple letter will go a long way to help Londoner. It is something simple that Singapore can learn for her bus stop sign.
