Nexus vs. SafetyCulture (iAuditor).

What SafetyCulture is great at

• A mature mobile inspection app with a huge template library.
• Cross-industry: works for retail, manufacturing, hospitality, construction, and many other verticals.
• Strong free tier for small teams.

Where it falls short for abatement and demolition

• It's a form builder, not a compliance system. You can build any inspection form, but the worker-credential side, the project-record side, and the 30-year retention archive aren't part of the product.
• No abatement-specific workflows. Class I-IV work types, NESHAP notifications, decontamination logs, and the rules that govern when each form is required aren't built in.
• Generic data model. An inspection record isn't structured around a worker-project-credential relationship; it's structured around an inspection template. Pulling a per-worker exposure record across years is a manual report-building job.

When to use SafetyCulture alone

• You need a flexible inspection app for multiple business units that aren't all abatement.
• Your compliance needs are simpler and credential tracking lives somewhere else.

When to use Nexus instead

• You're abatement or demolition specifically and need the workflows built around your trade's regulations.
• Worker credentials, project compliance, and the 30-year retention archive are real requirements, not optional add-ons.
