AR指南针 app for iPhone and iPad

Utilizing AR technology, the compass now displays instantly in the real environment, eliminating the need to look at complex 2D compasses. Moreover, with AR technology, you can mark directions, addresses, and altitudes in the real environment. It also allows you to record and screenshot within the app, capturing every wonderful moment.

This app utilizes the compass feature. Users need to enable location services in Settings -> Privacy -> Location Services and activate compass calibration in the system services.
