About

Built by a
First Responder

Praxis Training LLC develops training tools built from real field experience — not theory. Every product is designed for the operator who needs to perform under pressure, with equipment they may rarely touch between emergencies.

Based in the United States. All apps built independently in Swift for iOS.

01

Field-First Design

Every feature exists because it solves a real training problem. No bloat, no gamification — just the skills that matter when the meter alarms.

02

No Equipment Required

High-fidelity simulation means departments can train more frequently without instrument wear, calibration gas consumption, or scheduling constraints.

03

Works Offline

All core training features function without an internet connection — in the field, at remote sites, or in facilities with restricted network access.
