Description

Phruler is the only augmented reality measurement app that works like a real tape measure. Instead of struggling to aim your camera at distant points, you simply place your phone at a starting position, press a button, and move your phone to the end point. By measuring its own displacement in 3D space, Phruler delivers intuitive and accurate measurements for objects, corners, and dimensions that are impossible to capture with traditional point-and-shoot AR apps.

Designed to be a powerful tool that's also fun, Phruler includes features like Vertical-Only mode to measure the true height of complex objects, Challenge Mode to test your estimation skills, and "Instant Fun Facts" that connect every measurement to the world around you.

Key Features

  • Intuitive "Move-to-Measure" Mechanic: The most natural way to measure in AR—no aiming required.
  • Vertical-Only Lock: A revolutionary feature that isolates vertical movement to accurately measure the true height of any object, a feat no other AR app can reliably perform.
  • Ignore Obstacles: Measure true point-to-point distance, regardless of furniture or clutter in the way.
  • Fun & Engaging: Turn measuring into a game with Challenge Mode and learn something new with every measurement via Instant Fun Facts.
  • Highly Customizable: Personalize your app with over a dozen unique cosmetic themes.
  • LiDAR Enhanced: Leverages the LiDAR scanner on supported iPhones for maximum precision.
  • 100% Free & Ad-Free Core Tools: All measurement functionality is completely free, forever.
