Check whether a desk, shelf, or other surface is level with a responsive 3D bubble and clear angle readings. Spirit Level works offline on iPhone and iPad, with no ads, account, or subscription. TWO WAYS TO MEASURE Use Surface mode for two-axis tilt and total inclination. Switch to Horizontal to check tilt along the screen's left-to-right axis. Keep your device face up while measuring. CALIBRATE AND HOLD Set the current position as your zero reference with Calibrate. Hold a reading with the lock button, then tap again to resume live updates. Reset calibration in Settings to return to the gravity reference. MAKE IT WORK FOR YOU - Choose a level tolerance of ±0.1°, ±0.5°, or ±1.0°. - Enable haptic feedback on supported devices. - Keep the screen awake while measuring. - Use portrait or landscape layouts. - Choose Light, Dark, or System appearance. Your measurements stay on your device. Calibration and preferences are stored locally. For consistent readings, rest the device evenly. Cases and camera bumps can affect measurements. The tolerance setting determines when the app displays LEVEL; it is not a sensor accuracy guarantee. Support: https://spirit-level.gigirella.com/ Privacy: https://spirit-level.gigirella.com/privacy/
