Sidewalk - Contact Mapping is a business and productivity application available on the iPhone platform. This program allows users to visualize their contacts on a world map, providing a unique way to interact with contact information. Users can easily search for contacts by name, address, or organization, and filter them based on address labels such as "home," "work," "school," or "other." Additionally, the app offers a convenient feature to zoom in on the nearest contact for detailed information.

Sidewalk ensures complete privacy as all data is stored solely on the user's device. It's essential to note that only contacts with physical addresses can be mapped using this application, limiting the mapping functionality to specific contacts.
