Read full description

NDT Helper is the professional companion app for Non-Destructive Testing inspectors. Capture, organize, and report inspection defects with a streamlined mobile workflow designed for field use. SMART DEFECT CAPTURE Photograph defects with automatic watermarking that stamps each image with the defect ID, timestamp, category, and dimensions. No more manually labeling photos after the fact. Use the built-in zoom control for detailed close-ups of cracks, porosity, undercuts, and other indications. PROJECT MANAGEMENT Organize your work into projects, each containing its own defects, photos, and diagrams. Track defect status through the full review lifecycle: Pending, Progression, Static, Repaired, or Missed. Filter and browse defects in a visual grid with color-coded status badges. EQUIPMENT TRACKING Maintain a complete inventory of your NDT equipment with serial numbers, calibration dates, and maintenance status. Get clear visibility on which instruments are calibrated, due soon, or overdue. Supports all major NDT methods: UT, MT, PT, RT, VT, and ET. INTERACTIVE DIAGRAMS Upload technical drawings or weld maps and place color-coded defect markers directly on the diagram. Tap any marker to see full defect details. A built-in legend shows status at a glance — perfect for client presentations and final reports. RAW DATA RECORDS Log raw inspection data with client information, location details, and linked equipment. Attach photos and associate records with specific projects for complete traceability. TEAM COLLABORATION Share projects with teammates using simple 6-digit codes. Push and pull changes to keep everyone in sync. See collaborator count and pending changes at a glance. WORKS OFFLINE All data is stored locally on your device. Capture defects, manage equipment, and build reports without an internet connection. Sync to the cloud when connectivity is available.
