## Description

The most elegant way to measure anything in your photos. Free to try, no fuss.

Measure anything in any photo.

Take a photo or import one from your library, place a reference object you already know the size of, and instantly calculate real-world measurements — lengths, angles, and areas — directly on the image.

How it works
Set a reference line on a known object in your photo. From there, every measurement you draw is automatically calculated in real scale.

What you can measure
Ruler — measure distances and lengths
Arrow — annotate with directional measurements
Angle — measure the angle between any two lines
Area — tap points to outline a surface and calculate its area

Built for precision
Works entirely offline — no internet required
Metric and imperial units
Pinch to zoom for precise point placement
Undo and redo any change
Hide or show your reference line at any time

Tips for accurate results
For best accuracy, make sure your reference object and the object you're measuring are in the same plane, and that the camera was parallel to both when the photo was taken. Perspective distortion affects results.

Measurements are estimates based on the reference you provide.

## Rankings

- #274,653 — Overall

## Review summary

Most reviews describe stability and usability problems: crashes on startup, the app won’t load or opens and immediately closes, and you cannot click or obtain measurements. A minority report it works at times and can provide relative lengths for room planning. The app appears not updated recently and developers are unresponsive, which compounds user frustration.

### Pros

- Gives relative lengths for measurements
- Useful for room planning off floor plans
- Some users report it works at times

### Cons

- Frequent crashes and startup failures (won’t load / exits immediately / never opens)
- Non-functional: cannot click or obtain measurements; no output
- Not updated for a long time and developer unresponsive
- Ruler/measurement tools buggy; arrows are hard to move
