TV Antenna Compass USA is a compass app designed specifically for iPhone users in the United States. The app assists users in pointing outdoor TV antennas accurately by analyzing addresses and displaying tower maps with antenna pointers. It also provides a compass heading feature to align antennas properly. The app includes a menu with options to view channel lists, broadcast tower info, predicted signal strengths, compass headings for channels, and distances from the entered address to broadcast towers.

For users aware of the magnetic compass heading, entering the address and using the compass feature simplifies antenna alignment. Alternatively, users can access channel and tower info to determine magnetic directions for each channel. The app's recommendations assume the use of outdoor directional antennas installed at optimal heights for effective reception, making it a valuable resource for antenna positioning.
