Professional training tools for hazmat technicians, firefighters, and first responders. Built to work where it matters — in the field, in the classroom, and on the incident scene.
Every product is built from field experience — designed for the operator, not the classroom. No subscriptions required to train. No internet needed in the field.
A faithful recreation of a real multi-gas instrument with PID — sensor responses, cross-sensitivities, alarm behaviors, fresh-air calibration, and vapor-density stratification. Train solo with Guided Scenarios or run instructor-led Controller and Sampler sessions.
Multi-profile peptide protocol and health metrics tracker. 171-compound library, body composition snapshots, vial inventory with reconstitution tracking, and a full body map with trend indicators. Built for serious self-optimization.
An AI-powered prep command center for physique athletes — AI coach chat, an adaptive workout generator, full contest-prep tracking, HealthKit, and an Apple Watch app. Private and on-device. Coming soon to the App Store.
Free web-based training covering every sensor in a multi-gas instrument — technical background, operational considerations, and knowledge checks. No login, no app required.
Praxis Training LLC is the work of John Tramell — a career firefighter and HazMat technician, health and fitness enthusiast and triathlete, and independent developer who builds the tools he wishes he'd had. What began with high-fidelity HazMat training simulators has grown into something broader: apps for the disciplines he actually lives — emergency response, training and competition, and long-term health.
The throughline is the name. Praxis means putting knowledge into action — on the incident scene, under the bar, on the course, and in everyday life. Grounded in faith and family, John builds for the person who has to perform when it counts, and won't ship anything he wouldn't use himself. Every app is written independently in Swift, built to work offline and keep your data on your device.
Every app comes from a discipline John actually practices — the fireground, the gym, the long game of health. Built by a user, not a focus group.
Praxis means knowledge in action: tools for people who have to perform under pressure — whether the meter alarms or the clock starts.
Your training and health data stays yours. Core features run offline, on your device, with no account required to get to work.
Grounded in faith, family, and consistency — made to make you better over years, not to chase a trend.
