London Tube is an iPhone application that allows you to search for the nearest London Underground stations in augmented reality.
London Tube also lets you download (for a small fee) other points of interest databases to the application. These include Food & Drink, Leisure, Attractions and Accommodation. Using London Tube you can then locate all the nearby points of interest that you have downloaded on Google Maps and through the Augmented Reality view.
The London Cycle Hire (TfL) docking stations have just been added to the Leisure point of information database. Now if you download the Leisure POI's you can locate the nearest Cycle Hire docking stations to your present location. You can either view the nearest docking stations on Google Maps or view them in augmented reality.
In the augmented reality view the iPhone vertical position will give you a 360-degree view of all docking stations near your location, updated in real time as you walk the streets. The iPhone horizontal position will display a list of all the nearest docking stations. When a docking station is selected, a red arrow (compass) is displayed to show the direction and the distance to that point.
