This app allows you to measure tilt, similar to a level tool.
How to use: Place the device on the surface to be measured, ensuring the flat side of the device is supported. If using the device vertically, select the vertical option; if using it horizontally, select the horizontal option.

The maximum range of your device's sensor varies. Regardless of the maximum range, all angles are covered. Simply choose the correct orientation: vertical or horizontal. This ensures you remain within the measurement range. Any angle not covered by one orientation will be covered by the other. The tilt is measured accurately as long as it remains within the selected orientation.
