About this app

A simple and precise spirit level.

Hold your device horizontally and press it against an object to display the angle of inclination. Please make minor adjustments in advance to compensate for the unique tilt caused by the device's camera protrusions or case.

What’s new

An option to remove ads is now available. We have also resolved an issue where poor network conditions could cause the app to freeze during startup, ensuring a smooth launch every time.
