The idea
A mobile app built for people who do physical site inspections — fire safety, food safety, OSHA compliance, property condition audits — and often work in basements, warehouses, or rural sites with no signal. It loads a structured checklist template, lets the inspector walk through it tapping pass/fail/NA, attach a geotagged photo per item, and add voice-to-text notes, all with zero network dependency. The moment the device gets connectivity again, it syncs and renders a signed, timestamped PDF report ready to email or file.
Why build this
Compliance inspection is still overwhelmingly paper-and-clipboard or a general-purpose form tool (Google Forms, Jotform) that quietly breaks the moment there's no signal, which is often exactly where inspections happen. Firms doing this work bill by the inspection, so any time lost re-typing notes from a paper form back at the office is pure margin loss. On-device transcription and OCR are now cheap and good enough to run locally on a mid-range phone, and structured PDF generation is a solved problem — the gap is a tool that treats offline as the default case instead of an edge case, and that produces a report format auditors and regulators actually accept without reformatting.
Stack sketch
- Frontend: React Native (Expo) with SQLite (via
expo-sqliteor WatermelonDB) for fully local checklist and media storage - Sync: a lightweight sync layer using CRDT-style last-write-wins per checklist item, backed by a simple Postgres + S3-compatible object storage backend
- Voice notes: on-device Whisper (whisper.cpp compiled for mobile, or Apple/Android's built-in speech APIs) for transcription with no upload required
- PDF generation: server-side with a headless Chromium/Puppeteer render of an HTML report template, triggered on sync
- Photo geotagging: EXIF GPS + device sensors, stamped at capture time before any sync happens
- Auth/tenancy: simple org-based multi-tenant Postgres schema, since customers are firms with multiple inspectors, not individuals
Scope for v1
- One checklist template format (JSON schema) that an admin can build via a simple web form — no drag-and-drop builder yet
- Offline checklist completion with photo + note capture, local persistence, and background sync when online
- One PDF report layout, good enough for general compliance use, not per-industry customization
- Single-org accounts with a handful of inspector seats; no client-facing portal yet
- Out of scope for v1: e-signature capture, offline peer-to-peer sync between inspectors, industry-specific regulatory templates (fire code, OSHA 300 logs, etc.)
Where it could go
The natural expansion is a library of pre-built regulatory templates per industry — fire marshal checklists, USDA food safety forms, property condition reports for landlords — sold as an add-on or used to justify vertical-specific pricing tiers. A second path is opening a read-only client portal so the business being inspected can see report history and remediation status over time, which turns a one-off inspection tool into a recurring compliance relationship. Longer term, aggregating anonymized failure-rate data across inspections in the same vertical could support a benchmarking or risk-scoring product for insurers.
Watch out for
Report formats that satisfy a given regulator or insurer are often oddly specific and change slowly but unpredictably by jurisdiction, so treat the PDF template as configuration data from day one rather than hardcoding layout — retrofitting that later is painful. Also budget real testing time for sync conflict handling: two inspectors editing overlapping sections of the same site's checklist while both offline is a genuine edge case in team accounts, not a hypothetical one.
