AR Ruler - Camera Measure

AR Ruler - Camera Measure turns your phone into a precise measuring tool by using the camera and a standard credit card or ID as a physical reference for calibration. Instead of relying on shaky accelerometer data, the app asks you to place a card in the guide frame, tap a starting point and an ending point, and then displays the exact distance on screen in real time. This makes it handy for DIY projects, quick furniture checks, package measurements, and any situation where you want reliable, millimeter-level results without carrying a tape measure.

Key Features

⭐ Card-calibrated accuracy: AR Ruler - Camera Measure uses a standard card to calibrate the camera and avoid drift, delivering more stable readings than accelerometer-only tools.

⭐ Two-point measurement: Tap Point A and Point B on the screen to get an immediate, precise distance between any two visible points.

⭐ Neon visuals: A crisp, futuristic interface with clear neon guides makes measurements easy to see in most lighting conditions.

⭐ Manual calibration: A built-in slider lets you fine-tune measurements for maximum precision when needed.

⭐ On-screen ruler: A side ruler provides a quick, traditional reference without leaving the camera view.

Advantages

✅ Reliable accuracy thanks to physical card calibration, reducing errors caused by handset movement.

✅ Fast and intuitive workflow: set the reference, tap two points, read the result instantly.

✅ Versatile utility for home renovation, shipping checks, furniture sizing, and on-the-go measurements.

✅ Pocket-sized convenience—AR Ruler - Camera Measure replaces the need to carry a tape for many everyday tasks.

Disadvantages

❎ Requires a standard credit card or ID to calibrate before taking measurements.

❎ Measurement range and accuracy depend on camera field of view and lighting, so very long distances may be less precise.

❎ Only measures between visible points in the camera frame, so hidden or obstructed dimensions cannot be captured.
