SmartRuler press kit

SmartRuler uses your phone's camera and augmented reality to measure the real world. Point your phone at a floor, wall or object, tap to place points, and SmartRuler shows the length, angle, height, area or volume as a label on the live camera view.

Beyond straight lines, SmartRuler calculates the area of rooms and irregular shapes, the volume of boxes and cylinders, and can scan a room to create a floor plan. Chain measurements capture every wall in a row, and box preview shows how much space furniture will take up before you buy it.

The app also works as an everyday toolkit, with a compass, a spirit level, an on-screen ruler and a ring sizer that reads US, UK and EU sizes. Measurements can be saved as photos, grouped into project folders and shown in metric or imperial units.
