Spirit Level

Turn your phone into a handy bubble level for everyday jobs around the house. Hang a picture, mount a shelf, align furniture or check whether a surface is flat: Spirit Level reads your device's accelerometer and shows the tilt instantly.

FEATURES
• Live X and Y angle readout in degrees.
• A separate bubble tube for each axis.
• Circular 2D gauge showing both axes at once.
• Three precision modes: Rough, Normal and Fine.
• One-tap calibration and a reset back to the factory zero.
• Hold mode that freezes the reading when the screen is out of sight.
• Haptic feedback and a green screen the moment the surface is level.
• Dark, glare-free interface.
• Works fully offline. No account, no sign-up, no personal data required.
• Available in 32 languages.

HOW TO CALIBRATE
Place the phone on a surface you trust to be flat and tap Calibrate; the current position becomes the new zero. Tap Reset to return to the sensor's own zero.

PLEASE NOTE
Spirit Level is a simulation tool based on your phone's built-in sensors. Accuracy depends on your device's hardware and on how flat the phone lies. It is not a substitute for a certified measuring instrument and must not be used for work that requires professional measurement.
