About this app

Snap Ruler turns your phone into an AR tape measure.
Point your camera at any object, tap to set a start point, tap again for the end point — Snap Ruler shows the exact distance instantly, overlaid right on what you're measuring.
Key features:
• Real AR measuring — no need to touch the object, just point and tap
• Ruler-style overlay with tick marks, just like a real tape measure
• Switch between metric (cm, m) and imperial (in, ft) units anytime
• Tap the measurement for more detail — see the angle and distance from your camera too
• Undo or clear points anytime to fix a mistake
• Save a screenshot of your measurement with the object in view
• Keep a labeled history of past measurements, so you always know what each one was for
Whether you're measuring furniture before you buy, checking if something fits, doing quick home projects, or just curious how big something is — Snap Ruler makes it fast and effortless.
No tape measure, no guessing. Just snap it.
Requires a device with ARCore support.
AR camera ruler — measure anything instantly with your phone's camera.
