Tape Measure: Measuring Ruler

Measure objects with your phone

Tape Measure: Measuring Ruler by Grymala apps is a measuring tool for people who want to check lengths or plan a space without reaching for a physical tape. It uses the phone camera for augmented-reality measurements, and also offers a photo-based ruler for measuring an object in an image. The listing reports 10,000,000+ installs and a 4.2-star rating from 277,747 reviews.

Camera-based tools, with limits

The AR tools can measure a line, distance to a point, angles, area and perimeter, volume, a path, or height relative to a detected surface. You can choose units such as centimetres, metres, feet, yards, millimetres or inches. These measurements depend on the app detecting a suitable surface, and the AR functions require a device that supports ARCore.

The photo ruler works differently: it uses an object of known size in the same picture as the item you want to measure. The objects need to be in the same plane, with the camera parallel to them, to reduce perspective distortion. It may suit quick estimates, but the setup matters if you need a dependable result.

What it asks of your phone

Camera access is central to the advertised measuring methods: the app needs camera images for AR and photo measurements. The supplied listing information does not say what other phone access it requests, how often it shows ads, or whether it offers in-app purchases. Check those details on the app’s store page before deciding.

Check what is included

Some capabilities are described as available only in “Core,” but the supplied information does not explain the plan, its price, or which specific tools are restricted. If you need a particular measurement mode, confirm that it is included before relying on the app. Treat camera-based results as estimates and verify important dimensions with a physical measuring tool.
