Field
vs the per-seat native field app
An offline-first app your engineers open in any browser — no app-store install, no per-seat licence. Jobs only reach engineers whose certifications are valid, and every action is written to a tamper-evident audit trail.
Why it wins
- Offline-first PWA — works on any device, installs with no app store
- Cert-aware dispatch: expired certifications block assignment automatically
- Every field action hash-chained into a 7-year tamper-evident audit trail
- UK data residency (eu-west-2, London) by default
