Measure Master

Measure Master helps you estimate length, perimeter, and area from a single photo using Perspective Mode.
Set a reference rectangle, correct perspective, and get consistent estimates—ideal for quick planning and layout checks.

■ Screen Mode – Draw and estimate on images

Load a photo from your gallery or start with a blank canvas, then draw line segments and closed shapes directly on the screen.

The app provides estimated lengths, perimeters, and areas based on your drawing and device calibration.

A built-in Screen Guide explains the basic workflow, and you can show or hide guides at any time.

■ Perspective Mode – Adjust estimates on tilted photos

When a photo is taken at an angle, simple on-screen drawing may distort proportions.

Perspective Mode lets you:

Draw the shapes you want to estimate on the photo

Define a reference rectangle around an object with known dimensions

Adjust perspective so estimates become more consistent across the image

A step-by-step Perspective Guide is included to help you place the reference correctly.

■ AR Mode – Estimate distances in real-world scenes

Use your device’s AR capabilities to estimate distances in physical environments.

Tap to place points in space and visualize connected segments directly on the camera view.
You can reset, redraw, and capture the current AR scene as an image for reference.

An AR Guide explains how to get tracking ready and how to place points effectively.

■ Configuration – Tune the app to your workflow

Measure Master includes flexible configuration options:

Calibration (Zeroing)
Enter a known reference once to keep on-screen estimates consistent on your device.

Units & display
Choose units (mm, cm, m, inch, etc.) and control decimal precision.

Drawing behavior
Adjust line thickness, snapping distance, angles, and visual preferences.

Language & guides
Switch supported languages and show or hide on-screen guides.

Who is this app for?

People who want to estimate dimensions from photos during planning or review

Designers, remodelers, and exhibitors making rough layout checks

Engineers or creators who sketch on images and need quick visual estimates

Anyone exploring simple AR-based distance estimation without complex tools

Accuracy notice

Measure Master is not a certified measuring instrument and is not intended for legal, construction, safety, or surveying use.

Results are estimates and depend on factors such as:

Calibration accuracy

Placement of reference shapes

Photo angle and lens distortion

AR tracking conditions

For critical or final measurements, always verify results using professional tools.
