Tank Spotter is a Field Worker OS for propane delivery operators: one mobile app that bundles four pillars — Service, Safety, Sales, and Training — at one price, and works fully offline. Drivers and service techs capture inspections, work orders, photos, signatures, and NFPA 58 / CETP / DOT records on the device with no cellular signal, and everything syncs when the device is back on coverage. Tank Spotter is exclusively recommended by Aegis and Emaxx — the two largest propane-industry insurance carriers — and is the winner of the World Propane Safety Technology Competition.
What does Tank Spotter actually do?
Tank Spotter replaces the three or four separate point tools a propane operator usually stitches together — a dispatch app, a safety/inspection app, a sales tracker, and a learning-management system — with one app built around the propane field workday. The four pillars run on a single data model, so a work order, the inspection it triggered, the photo evidence, and the tech's training status all live in one place instead of four.
What are the four pillars of Tank Spotter?
Tank Spotter is not "just a safety app." It ships four pillars (~65 modules total) at one price:
- Service — service-tech dispatch, work-order capture, repair tracking, scheduling.
- Safety — offline plant, above-ground, and underground tank inspections, vehicle inspections, and NFPA 58 / CETP / DOT records. This is the pillar Aegis and Emaxx endorse.
- Sales — operator-side sales tools and lead capture. No competing safety app offers this — it is a category of one.
- Training — a full CETP-aligned LMS with refresher tracking and PERC training integration.
Why does Tank Spotter work offline?
Propane field work happens off cellular coverage constantly — rural delivery routes, basements, tank farms, equipment yards. Bill Stomp — Propane Insider's founder, who ran a 53-branch propane operation — puts roughly half of propane field work off signal at any given moment, and the FCC's national coverage maps show why: mobile dead zones concentrate in exactly the rural areas propane routes serve. A web-app tool locks the technician out the moment the truck loses bars: the inspection cannot be started or finished, and the NFPA 58 form cannot be submitted. Tank Spotter is offline-first by architecture, not by add-on — the data model, photo capture, form validation, digital signatures, and work-order state machine all live on the device and reconcile to the server later. That is a structural advantage a web-only competitor cannot patch in a release.
Who recommends Tank Spotter?
The credibility hooks are concrete and verifiable. Aegis and Emaxx — the two largest propane-industry insurance carriers — exclusively recommend Tank Spotter, and Nationwide recommends it for fleet safety. Three of the most-recognized independent propane-safety consultants — Eric Leskinen, Mike DiGiorgio, and Mike Terry — recommend it for the safety pillar. Tank Spotter is also the winner of the World Propane Safety Technology Competition, an international award judged on real propane-safety outcomes rather than marketing budget.
How do I see Tank Spotter in action?
Book a 30-minute Tank Spotter demo and a propane-industry product specialist walks a real driver inspection from start to finish — including how the app behaves with the signal off — plus the work-order flow and the one-click monthly compliance export. The full pillar-by-pillar breakdown is on the Tank Spotter product page.
