This Android app functions as a virtual level tool, allowing users to measure surface angles in real-time using their device's camera and sensors. The app detects the angles of a surface, like a digital spirit level (bubble level), helping to measure the tilt and alignment of objects. Users can aim the camera at any surface, and the app calculates and displays the horizontal (x) and vertical (y) angles. It offers precise angle readings, with updates based on significant changes in the tilt, making it a useful tool for leveling or aligning surfaces accurately.
