How to use Image Meter

Steps, videos and tips for the app and its tools.

Turn photos and plans into editable measurement drawings. Add a known-size reference, place lengths, angles and areas, then annotate and export a picture or report with the context intact.

Getting started

Choose a picture

The app opens the Full Image Meter library. Open an existing photo or sample, import one, or take a picture, then edit its drawings.

Basics

Step by step.

Get started

  1. Choose a picture

    The app opens the Full Image Meter library. Open an existing photo or sample, import one, or take a picture, then edit its drawings.

  2. Choose the right edition

    In Angle Meter, Clinometer and Easy Laser Bubble Level, start from an existing photo or capture and use Angle, Free angle, Distance, Draw or Text. The extra Area, analysis and library features described here belong to Full Image Meter in its standalone app and Toolbox.

  3. Open a photo and add measurements

    Pick a photo from the list or a sample, import one with Add, or take one. Tap Tools and pick a tool: draw an angle in one stroke, tap points with Free angle to see inner and outer angles, measure with Distance or Area, or add shapes, labels, notes and pen marks.

Measure

  1. Adjust drawings and inspect details

    Select a drawing to move it or adjust its handles. Pinch to zoom and pan. Use the grid and magnifier for placement; undo or redo edits.

Save

  1. Set a reference and save the picture

    Pick Scale line under Reference, drag it along something of known size and enter its length and unit; for a wall or floor seen at an angle, use Perspective plane. Manage drawings in Layers. ⋮ › Save puts the marked-up picture in your gallery, and the drawings stay editable when you reopen the photo from the list.

Guided tour

Try these steps in the app. All tour instructions stay readable here.

  1. Open a practice image

    Start from the library and open a sample, import a photo or a PDF page, or take a picture. Choose a tool before placing points or drawing on the image.

  2. Give a known object its size

    Place a Scale line on a known length and enter the real length and unit. Zoom in when setting the endpoints; a long, clearly visible reference reduces placement error.

  3. Work on a sloping view

    Use Perspective plane for a wall or floor seen at an angle. Match its four corners to a rectangle with known size on the same plane as the measurements.

  4. Review suggestions before adding them

    The Full app offers edge snapping, shape suggestions and reading of printed sizes. Check the selected shape or value, then confirm it; real-world lengths still depend on a correct reference.

  5. Annotate and keep it editable

    Add dimensions, areas, labels and notes, and adjust them with their handles. Save a marked-up picture for sharing, then reopen the photo in Image Meter to edit its retained drawings.

Tool guides.

Each tool in Image Meter has its own guide.

Tips.

Set a known reference size before trusting a length; without it the drawing reads pixels.

Choose a long, clearly visible reference and zoom in before placing its endpoints.

For a wall or floor seen at a slant, use a four-corner perspective reference on the same plane as the measurement.

Keep measurements linked to the appropriate reference when the photo contains more than one surface.

Review detected shapes and printed sizes before confirming them; suggestions do not establish real-world scale.

Reopen the original photo in Image Meter to edit its drawings; the image saved to the gallery is a flattened copy.
