ITS Verify goes beyond the simple task-based verifications provided by ITS Go to enable verification of a worker’s qualifications against the more holistic requirements of a specific job, including requirements for span of control (SoC) and “critical” tasks, such as those for which records are required to be kept for the life of the pipeline. Key Features: • Scan worker’s eWallet card in the field to verify workers’ qualifications against custom jobs that were created in ITS platform • Assign workers to job crew based on qualifications, SoC requirements, and D&A status • Capture digital signature of assigned qualified individual for “critical” tasks • Identify and record non-qualified workers Benefits: • Simplifies and digitizes field verification reports (FVRs), while enforcing SoC • Eliminates the inefficiencies of previously paper-based processes • Centralizes critical OQ records in one system, streamlining reporting and auditing • Easily comply with regulatory and records retention requirements, including for critical tasks, safeguarding the defensibility of your OQ program.

Verdict
The clearest difference is rating: Nautilus at 4.6 against ITS Verify's 3.7. Nautilus also leads on ratings volume (3.2K vs 7) and update cadence (every 11 days vs every 2 months). ITS Verify's advantage is in-app purchases (none vs 3) and iOS requirement (15.0 vs 26.0). On price, ads and device support there is nothing between them.
