AR Measure

What it does

AR Measure turns your phone's camera into a real-world tape measure using augmented reality. Point at any surface, tap to set a start point, move to your endpoint, and read the distance instantly on screen — no physical ruler needed. It works entirely on your device, so there's no internet connection required, no account to create, and nothing is ever uploaded anywhere. Whether you're checking if a sofa fits a wall, estimating a room dimension, or measuring a piece of furniture before you buy, AR Measure gives you a fast, private, always-available answer. It's completely free, runs fully offline, and keeps all measurements local to your phone.

How to use the AR Measure

1. Open AR Measure and point your camera at a flat surface with good lighting.
2. Tap the screen to place your starting point — a dot will anchor to the surface.
3. Slowly move your phone to your endpoint, then tap again to complete the measurement.
4. Read the distance displayed on screen in your chosen unit (cm, in, ft, or m).
5. Tap the trash icon to clear and start a new measurement, or take a screenshot to save.

Frequently asked questions

How accurate is AR Measure?

Accuracy depends on your device's LiDAR or depth sensors and good lighting. On devices with LiDAR (like newer iPhones) you can expect ±1–2 cm. On camera-only devices, results are best on flat, well-lit, textured surfaces.

Does it work without internet?

Yes, completely. AR Measure runs entirely on your device using the camera and motion sensors — no internet connection is required at any point.

Can I measure height or vertical distances?

Yes. You can measure in any direction — horizontal, vertical, or diagonal — as long as you can keep your phone steady while moving from one point to another.

Does the app store or share my measurements?

No. All measurements stay on your device and are cleared when you close the tool. Nothing is uploaded or shared.
