About Changeover Master — SMED & Production Changeover Command
Changeover Master is a purpose-built digital command terminal for machine operators and production teams executing SMED (Single-Minute Exchange of Die) changeovers. It transforms the chaotic, paper-based changeover process into a structured, real-time workflow that reduces downtime, eliminates errors, and boosts OEE. The app provides a live runbook with step-by-step instructions, reference photos, tooling and material lists, and built-in timers to track every phase. Operators can mark steps complete, record actual times, and compare performance across shifts to drive continuous improvement.
Designed for the factory floor, Changeover Master works fully offline using IndexedDB for local data persistence — no internet, no sign-up, no mock data. It's a production-ready tool that respects the reality of industrial environments: connectivity is unreliable, gloves are on, and time is money. The premium, responsive interface is optimized for tablets and rugged handhelds, with large touch targets and high-contrast visuals for readability in low-light conditions.
The app includes a comprehensive first-piece inspection module, allowing operators to document quality checks with photos and pass/fail criteria, ensuring that the first part off the line meets spec before full production ramps up. Deviations from standard work are logged with mandatory approvals, creating a secure audit trail. The shift comparison feature analyzes changeover times across shifts, highlighting best practices and bottlenecks, while reports and KPIs give supervisors actionable insights.
Changeover Master is not just a timer — it's a complete changeover management system. It digitizes tribal knowledge into reusable runbooks, standardizes work across all lines, and empowers operators with the information they need at the point of action. Whether you're in automotive, packaging, food & beverage, or any discrete manufacturing environment, Changeover Master helps you achieve world-class changeover performance.

FAQ
Is Changeover Master an AI tool?
No, Changeover Master is a fully functional offline app that does not rely on AI. It uses deterministic logic to manage checklists, timers, and data storage, ensuring reliability in industrial environments.
Does Changeover Master require an internet connection?
No, the app works entirely offline. All data is stored locally in your browser's IndexedDB, so you can use it anywhere, even without Wi-Fi or cellular coverage.
Do I need to create an account or sign up?
No sign-up is required. You can start using Changeover Master immediately after opening the app. All data stays on your device.
Can I customize the runbooks for my specific machines?
Absolutely. The Runbook Library allows you to create, edit, and manage runbooks for any machine or product changeover. You can add steps, photos, tools, and estimated times.
How does the first-piece inspection feature work?
After the changeover, you can navigate to the First-Piece Inspection section, where you can define inspection criteria (dimensions, visual checks, etc.). During the inspection, you can take photos and mark each criterion as pass or fail. If any fail, a deviation is logged and requires approval.
Can I compare performance between different shifts?
Yes, the Shift Comparison feature aggregates changeover times and other metrics by shift, allowing you to identify best practices and areas for improvement.
Is Changeover Master free to use?
Yes, the app is completely free and will remain so. It's designed to be a practical tool for production teams without any cost barriers.
