AR Ruler App: Tape Measure Cam

Measure with your phone camera

AR Ruler App: Tape Measure Cam turns an Android phone into a camera-based measuring tool. It is suited to DIY projects, furniture checks, room planning and quick estimates when you do not have a tape measure nearby. The app uses augmented reality to place measurement points in the space around you, so you can check distances without carrying separate equipment.

Several ways to check size

Use the ruler for linear measurements and switch between common units including millimetres, centimetres, metres, inches, feet and yards. The app also supports area and volume calculations, which can help when estimating a surface, room or object. Height and angle tools add options for measurements that are awkward to take with a standard tape.

Room and image tools

For larger spaces, AR Ruler App can build room layouts from measurements and create floor plans for PDF export. That makes it useful for rough planning before arranging furniture or starting a home improvement task. A photo measurement mode and an on-screen ruler provide alternatives for smaller objects or situations where live camera measurement is not practical.

Because the app relies on camera-based augmented reality, results depend on how clearly the phone can detect the surrounding surfaces. It is best treated as a convenient guide for everyday measuring and planning rather than a replacement for precision equipment when exact dimensions matter.
