Spirit Level: 3D Bubble

See your surface from a new angle. Spirit Level turns your iPhone or iPad into a spirit level with a responsive 3D instrument, a glass bubble, and clear angle readings.

Place your device face up to check a surface, or switch to Horizontal mode to measure tilt along the screen's left-to-right axis.

FEATURES

• A real-time 3D level with a metallic body and illuminated bubble.
• Surface mode with two-axis readings and total surface inclination.
• Horizontal mode for checking one axis at a time.
• Calibration to use the current surface as your zero reference.
• Hold to freeze a reading while you move the device.
• Adjustable level tolerance: ±0.1°, ±0.5°, or ±1.0°.
• Optional haptic feedback on supported devices and a keep-awake setting.
• Portrait and landscape layouts.

No account or internet connection is needed. Preferences and calibration stay on your device.

For consistent readings, make sure the device rests evenly. Cases and camera bumps can affect the result. The tolerance setting defines when a reading is considered level; it is not a sensor accuracy guarantee.
