WeldGauge turns your iPhone into a portable weld inspection station. Capture a photo of any weld, calibrate it against a known reference, and measure imperfections directly on-screen — with instant pass/fail evaluation against EN ISO 5817. WHAT MAKES WELDGAUGE UNIQUE Unlike generic measurement or photo annotation apps, WeldGauge is purpose-built for welding quality control. It combines calibrated dimensional measurement with built-in welding standards evaluation in a single workflow — something previously only possible with dedicated lab equipment or desktop software. CAPTURE & IMPORT • Built-in camera with up to 20× zoom for close-up weld detail • Import existing photos from your library • Automatic background removal to isolate the weld profile • 45° rotation for angled weld orientations CALIBRATE • Place any known reference (ruler, gauge block, coin) in the photo • Draw a calibration line and enter the real-world dimension • The app calculates a precise pixel-to-millimeter ratio • Re-calibrate anytime without losing measurements MEASURE • Tap to measure linear distances on the calibrated image • Measure reinforcement height, undercut depth, misalignment, throat thickness, and more • Pan, zoom, and rotate freely while measuring • Edge detection overlay highlights weld boundaries automatically EVALUATE AGAINST EN ISO 5817 • Select the imperfection type (502, 504, 507, 508, 5011, 5213, 512) • Enter wall thickness and weld width • Instant evaluation against quality levels B, C, and D • Clear pass/fail result for each level • Built-in reference guide with illustrations for every imperfection type PIPE FITTINGS LIBRARY • Searchable database of standard pipe fittings (elbows, tees, reducers, caps) • Dimensions and specifications for quick field reference • Filter by type and nominal size PROJECT MANAGEMENT • Organize inspections into projects with metadata • Store weld number, location, welder ID, and notes • Multiple measurements per project • All data persists locally — nothing is uploaded EXPORT & REPORTING • Export measurement results as structured reports • Share annotated photos with measurement overlays • PDF and CSV output for documentation FULLY OFFLINE & PRIVATE • Every feature works without an internet connection • Zero data collection — no analytics, no tracking, no accounts • All photos and data stay on your device • Perfect for field inspections in remote locations WHO IS IT FOR • Welding inspectors (CWI, IWI, CSWIP) • Quality control engineers • Fabrication shop supervisors • Welding students and trainees • Anyone who needs quick, standards-based weld evaluation on site WeldGauge replaces the workflow of "take a photo → transfer to PC → open CAD software → measure → look up the standard → calculate." Now it's one app, one device, one minute.

Verdict
The clearest difference is price: Goal Zero Power at Free against WeldGauge's $4.99. Goal Zero Power also leads on iOS requirement (15.1 vs 17.0). WeldGauge's advantage is update cadence (every 2 weeks vs every 3 months). On ads, in-app purchases and device support there is nothing between them.
