Shelf, frame, camera. One little helper.

Place your phone against a surface, read both axes and adjust its position to check the tilt.

Contact first. Then read.

A useful reading starts with how your phone meets the surface. A case or camera bump can change that contact.

Read the guide
  1. Hold a flat edge of your phone against the surface you want to check.
  2. Keep it steady and read the horizontal and vertical angle indicators.
  3. Use the reference control when you want to compare an angle.

What is a reference angle?

You do not always want to reach zero. You can take one position as your starting point and compare another with it. Move the slider, save a reference, then change the angle again.

This is an interactive explanation of a reference, not an exact copy of the app screen. It does not access your phone’s sensors or take real measurements.

For everyday checks. Use the right tool for critical measurements.

Readings are calculated from your phone’s motion sensors and are approximate. Surface contact, a case and device conditions can affect them. Use an appropriate physical measuring instrument for work that needs verified accuracy.

Keep it handy for your next project.
