PhoneLeveler guide

Online Angle Finder & Inclinometer

Use your phone to check a tilt or relative angle in degrees. It is useful for everyday alignment and reference checks, not certified measurement.

How to measure an angle

  1. Open the level tool on the phone you will use.
  2. Choose the angle option and place the same phone edge against the object.
  3. Hold still until the reading is Stable, then note the degrees.
  4. Calibrate only when you intentionally want a surface to become your reference.

Everyday checks

Check an intentional shelf slope, compare a picture edge with a nearby reference, or confirm a bracket before final tightening. The tool reports degrees; it does not claim slope units or surveying results.

Get a dependable reading

Remove a case if it stops the phone sitting flat. A camera bump can change the contact plane, so use a flat edge where possible. Sensor quality varies; recalibrate if a reading seems off and use a physical instrument for safety-critical work.
