About this app

Measure Right turns your Android camera or an existing photo into a calibrated measurement workspace for everyday projects, part inspection, fabrication, maintenance, and documentation.

Use it to:

• Calibrate scale from a known reference object or known length.
• Measure distances, diameters, radii, angles, parallel spacing, center-to-center distance, polygon area, flatness, and roundness.
• Freeze a live camera frame for stable point placement.
• Improve point placement with zoom, a precision loupe, crosshairs, grids, and edge snapping.
• Correct perspective with four-point plane calibration.
• Create reusable part templates and guided inspection sequences.
• Add tolerances and record pass/fail results.
• Save local measurement history and export annotated images, CSV data, backups, and PDF reports.

Measure Right works locally on your device. It has no ads, analytics, user accounts, subscriptions, or developer-operated cloud storage.

Camera measurements depend on calibration, camera angle, lens characteristics, lighting, image quality, and the measured surface. Verify results with an appropriate physical instrument before using them for safety-critical, medical, legal, or regulated decisions.
