Distance Meter is a complete measurement toolkit: AR distance measuring plus 15 specialized tools in one app. Powered by Google ARCore, it detects your device hardware and selects the most suitable measurement engine for maximum accuracy.
Leveling a shelf, measuring a room, estimating paint, or checking whether a box fits through a doorway — there is a tool for each job.
[AR Spatial Measurement]
• AR Distance — Tap to measure the distance to any point, with a live accuracy estimate.
• Height Meter — AR height for people, furniture, doors, and buildings.
• Width & Height — Get both in a single session.
• Area Calculator — Mark corners to measure floor area, wall space, or any surface.
• Volume Meter — Width, depth, and height in three guided steps. Ideal for boxes, cabinets, and luggage.
[Sensor & Assist Tools]
• Bubble Level — Circular spirit level with 3D liquid and bubble animation.
• Clinometer — Slope gauge covering 0° to 180°, with slope percent and ratio.
• Plumb Bob — Gravity-based digital pendulum for vertical alignment.
• Protractor — Touch and sensor based angle measurement, 0° to 180°.
• Screen Ruler — On-screen ruler in cm and inches, with card-based calibration.
• Frame Checker — Camera based alignment for frames, TVs, and shelves.
[Calculation & Planning]
• Room Measurement — Floor, wall area, perimeter, and volume in one calculation.
• Wall & Materials — Subtract doors and windows, then estimate paint and wallpaper.
• Space Fit Checker — Test every rotation of an object against a doorway before you move it.
• Round Object Meter — Diameter, circumference, cross-section area, and capacity.
• Multi-segment Path — Add up cable, pipe, and curved route segments.
[Smart Measurement Engine — 4 Tiers]
Your device is automatically matched to the highest tier it supports.
• Premium (Hardware Depth) — ARCore Depth with camera depth-output capability; confidence varies by device and scene.
• High (Depth API) — Depth-assisted ranging with live signal-quality checks.
• Standard (ARCore) — Plane and feature tracking with live signal-quality checks.
• Basic — AR distance measurement is unavailable; planning and sensor tools remain available.
[Accuracy Technology]
Several strategies are fused with confidence weighting: depth image, raw depth with confidence map, plane, point cloud, and anchor sampling. Outliers are removed and points are re-read from ARCore anchors as the map refines, so results stay stable while you move.
Five conditions are monitored while you measure: tracking, lighting, surface detection, feature points, and camera stability. A live indicator shows measurement confidence before you tap; it is not a guaranteed error bound.
[Key Features]
• AR distance measuring plus 15 tools in one app
• 4-tier AR engine (Hardware Depth → Depth API → ARCore → Basic)
• 6 units: meters, centimeters, feet, inches, yards, millimeters
• Measurement history with auto-save and undo
• Sound and vibration feedback
• Grid overlay and level indicators
• Dark and light mode with a clean one-tone design
• Home screen widget, status bar shortcut, and offline measuring
[Tips for Accurate Results]
• Ensure good lighting
• Move your device slowly during initialization
• Keep a steady hand — stability directly affects accuracy
• Measure textured surfaces (avoid mirrors, glass, plain white walls)
• Optimal AR range: 0.5m to 5m
[Disclaimer]
Measurement results are estimates based on AR technology and device sensors. Actual values may vary by device, environment, and conditions. This app is not intended for professional surveying or safety-critical applications.
