Bicycle Parking is a free iPhone app designed to facilitate finding and marking bike parking spots. Users can easily mark their parking locations by tapping "Park Here" and toggle between their parked spot and current location with a simple button. The app allows users to contribute to the public map by adding new bike parking spots using a drag and drop feature under the "Add" tab.

For those seeking existing bike parking locations, the "Map" tab provides a view of nearby spots, loaded based on the area being viewed. Additionally, users can access special features like "Upload Later" under the "Manage" tab, enabling them to save parking spots for later upload, perfect for areas with weak signals.
