Turn your Windows 10 device into an important tool in and around the house with this free app.

Use tiltmeter to ensure the picture on the wall is level, the garden drainage channel has the correct slope, the fence pole is not leaning over, or turn your simple spirit level into a smart level.

To use this app, the device should has at least one straight edge without any protrude button/connector, and the device should have an accelerometer sensor or g-sensor.

If the device accelerometer sensor is not properly align to your device, you can calibrate the sensor reading by:

• Lean the device’s straight edge against a known level surface
• Tap the ‘Calibrate’ button to reset sensor reading.
