Spirit Level
Measure tilt using your device's orientation sensor to check horizontal and vertical alignment.
Category: Life Tools
When to use?
Check if a shelf, picture frame, or table is level when you don't have a physical level tool.
How to use
- Open on a mobile device.
- Allow sensor permission.
- Place the device on the surface to see tilt readings.
Input Explanation
None required. Just lay your mobile device flat or stand it upright.
Calculation Basis
Accesses device accelerometer and gyroscope data via the DeviceOrientation API to compute tilt angles in real-time.
Usage Examples
- Hanging pictures & shelves - Check that wall-mounted items are not tilted.
- Table leveling - Verify that a dining or work table is level.
Examples
- Place your phone flat on a table to see if it tilts sideways
- Hold your phone edge against a photo frame to verify vertical alignment
Cautions
- Desktop PCs lack tilt sensors — this works on mobile only.
- Sensor precision varies by device; use a professional level for precision work.
FAQ
Does it work on PC?
Most PCs lack tilt sensors, so this is mobile-only.
How accurate is it?
Smartphone sensors have ±1–2° tolerance — suitable for rough leveling checks.
