PhotoRuler

Photo Ruler: The Ultimate Measurement & Annotation App Calibrate with a known object (credit card, coin, or custom size), then measure real-world length, width, area, and angles on any photo. Annotate like a site diagram: lines, arrows, shapes, and trade icons for electrical, plumbing, and architecture. Export a PDF or save images to your gallery for DIY projects, contractors, and architects. No ARCore required for photo measure. No data collected. HOW IT WORKS 1. Take or open a photo that includes a known reference (credit card, coin, or enter a custom length). 2. Set the scale once, then draw measurements: lengths, areas, angles, and custom shapes. 3. Label with trade icons and styles, then export PDF or save to your gallery. KEY FEATURES • Photo measure: lengths, widths, diameters, areas, and angles on your photos • Easy calibration: credit card, coin, or custom reference size • Annotation toolkit: lines, arrows, string rulers, shapes, and hatched areas • Trade icons: electrical, plumbing, architecture, and more • Magnifier and line styles for precise placement • Measurement history: reopen past sessions • Export: PDF with measurement key, or gallery images • Share-ready overlays with optional custom watermark WHO IT’S FOR DIY homeowners, contractors, architects, and anyone who needs dimensions from a photo without walking around with a tape measure. PRIVACY PhotoRuler does not collect your data. No data is shared with third parties (see Data safety on this listing). SUPPORT [email protected] PhotoRuler is a photo measuring and annotation app — not a live AR tape measure. Measure from photos with a simple card or coin calibration.
