The app's functions include measuring distances in a room with the camera using augmented reality. This allows simple distances, areas and even volumes to be measured.

The application is straightforward to use: You fix a point and draw a route from there. Areas and volumes are then intelligently suggested to the user, which the device can calculate.

Didactic advice and teaching ideas.

How well does the measurement work in everyday school life? Lighting conditions play an important role. Dark or very bright environments with strong sunlight are not recommended. In both cases, the measurement can be inaccurate. Secondly, the distance to the object is important. A distance of more than two and a half metres from the object being measured should not be exceeded to obtain accurate values.

Otherwise, the measurements are impressively accurate in both the centimetre and millimetre range. If you want to be really precise, measure with a tape measure. The comparison between augmented reality and manual measurement is also certainly valuable from a didactic point of view.

Nevertheless, the AR app is very suitable for measuring and comparing objects, rooms and distances in everyday school life.


  1. Measure is a free app from Apple.
  2. The camera can be used to capture objects and measure distances using augmented reality.
  3. Move the iPhone camera and point the circle at the point to be measured.
  4. Tap on the plus symbol to set a measuring point.
  5. Repeat steps 3 and 4 until the entire object has been measured.
  6. Tap the shutter button to take a snapshot of the measurement.
