NDT Vault
Read full descriptionHide full description
NDT Vault is a professional-grade inspection documentation tool built for Non-Destructive Testing technicians and engineers. Capture defects, manage equipment, generate reports, and collaborate with your team — all from your iPhone or iPad. CAPTURE & DOCUMENT DEFECTS Photograph defects directly within projects using the advanced multi-lens camera. Each photo is automatically watermarked with the defect ID, category, dimensions, and timestamp for instant traceability. 6 INSPECTION REPORT TYPES Generate standardized inspection records for MT, PT, PA, UT (Thickness), UT (Weld), and Visual inspections. Each form follows industry conventions with fields for procedures, acceptance criteria, test media, equipment used, calibration references, and detailed findings. EQUIPMENT TRACKING Maintain a complete inventory of your NDT instruments. Track serial numbers, manufacturers, calibration dates, and certificate numbers. Color-coded status indicators show at a glance which equipment is calibrated, due soon, or overdue. INTERACTIVE DIAGRAMS Import site diagrams or schematics and place defect markers directly on them. Tap any marker to jump to the full defect record with photos, dimensions, and review status. REVIEW WORKFLOW Mark defects as Repaired, Progression, Static, or Missed. Attach follow-up photos and notes to build a complete review history for every defect. EXPORT & SHARE Generate PDF reports or ZIP archives with watermarked or original photos. Share projects with teammates via 6-character codes. Collaborative projects sync in real-time so your entire team stays current. CLOUD COLLABORATION Convert any project to collaborative mode. Team members join with a simple code and all changes sync automatically. View shared projects on the web at ndtvault.botor.io. OFFLINE-FIRST Every feature works without an internet connection. All data is stored securely on your device. Cloud features activate when connectivity is available. BUILT FOR THE FIELD Dark interface designed for industrial environments. Fast camera access, minimal taps to document a defect, and efficient data entry for inspection forms. Why this works: - First paragraph is the hook — tells who it's for and what it does - ALL CAPS headers are scannable (Apple standard practice) - Each section is 2-3 lines max — no walls of text - Ends with the unique selling point (offline + dark UI for field work) - Keywords naturally embedded (NDT, inspection, defect, calibration, etc.)
