AngleLevel

AngleLevel turns your phone into a practical angle meter and spirit level for quick surface checks. It shows live tilt, pitch, roll, and flip angle readings with a clear instrument-style gauge, plus Zero, Lock, and Save controls for reference checks and measurement records. A built-in guide explains how to place the phone, set a zero reference, and read the result. Settings include display precision and smoothing for steadier readings. The app uses the device motion sensor locally to calculate angles and does not request dangerous Android permissions.
