Euclidar

Millimeter-accurate LiDAR measurements, straight from your camera. All offline, all private.

Turn your iPhone or iPad into a professional-grade measuring tool.

Euclidar uses the Apple LiDAR scanner in your device to capture touch-free distance measurements with millimeter accuracy — no tape measure, no second person, no guesswork.

Unlike simple AR ruler apps that read a single depth pixel, Euclidar fuses multiple depth frames in a single burst into one low-noise depth image, and corrects for your exact device's calibration offset — including case thickness. The result is a clean, annotated photo with measurement points, distance labels, and a confidence overlay you can trust, export, and archive.

KEY FEATURES Burst-Fusion Measurement Capture 5–40 depth frames and fuse them using confidence-weighted median filtering, outlier rejection, and edge-preserving smoothing — for measurements far more stable than a single depth snapshot.

Smart Cursor System Place multiple color-coded cursors directly on your depth image. Each one automatically corrects for surface tilt using real-time plane-normal detection — so measurements stay accurate even on angled surfaces like roof slopes or ramps.

Measurement Modes Point — absolute distance to an object from camera origin Segment — direct 3D distance between two points Angle — interior angle across three points

Live Quality Overlays See depth-quality issues in real time before you even capture — plus confidence heatmaps and an interactive, rotatable 3D point cloud after.

Built-In Gallery & Archive Every capture is saved with searchable notes and automatic GPS tagging. Filter, sort, rename, duplicate, or restore from the trash — all without an account or the cloud.

Export Ecosystem Annotated JPEG with labels and distances Special Euclidar file format for sharing between users

Offline & Private by Design No cloud, no accounts. Every measurement, photo, and point cloud stays on your device.

WHO IT'S FOR Trade & Installation: Measure door frames, window widths, and alcoves solo — and get it right on angled surfaces. Interior Design & Architecture: Document room dimensions and check furniture fit with photo-based records. Industry & QA: Repeatable, archivable measurements with exportable point clouds for CAD integration. Real Estate & Facility Management: GPS-tagged photo documentation and PDF reports, property by property. Research & Prototyping: Fast depth captures and colored point clouds for computer vision and ML datasets.

REQUIREMENTS iOS 17 or later, with an iPhone or iPad featuring an Apple LiDAR scanner (iPhone 12 Pro and later Pro models, iPad Pro 2020 and later).
