I need an app that handles lockout/tagout (LOTO) energy isolation specifically for machinery. The whole point is to let operators and safety managers follow, verify, and document every step of an isolation procedure directly on their phones or tablets, cutting paperwork and improving compliance. What the app must do • Store approved LOTO procedures for each machine. • Walk the user through every step with clear check-offs. • Capture photos and digital signatures as proof. • Generate a time-stamped log that exports to PDF or CSV. • Work offline and sync once a connection returns. I’m open on the tech stack—Flutter, React Native, or fully native are all fine as long as the result is fast, secure, and deploys to both iOS and Android stores. Data security and an intuitive UI for non-technical users are essential. Timeline is urgent: I need a working MVP ASAP. When you respond, let me know how quickly you can deliver each milestone and what information or assets you will need from me (existing SOPs, logos, color palette, etc.). Acceptance criteria • The app installs and runs on current iOS and Android versions. • At least one complete machinery isolation workflow can be created, followed, saved, and exported without errors. • Basic accessibility guidelines are met and the interface is clear for shop-floor staff. Experience with safety, compliance, or other industrial applications will be a big plus.

Hi there, I got the complete user flow. As I understand it, there will be different user roles including Admin, Supervisor/Safety Manager, and Operator. The Admin will manage machines, users, and approved LOTO procedures, the Supervisor will review, verify, and monitor isolation activities, while Operators will follow the approved isolation steps on-site, capture photos and digital signatures, and complete the workflow. Everything will be logged with timestamps and should continue working even when the device is offline. I can build the complete MVP, including the mobile application, secure backend APIs, admin portal, offline synchronization, PDF/CSV report generation, role-based access, audit logs, photo and signature management, and deployment for both iOS and Android. What I would suggest is using Flutter for the mobile application to maintain a single codebase for both platforms, Node.js (NestJS) for a secure and scalable backend, PostgreSQL for structured data, SQLite on the device for offline storage, and AWS S3 (or equivalent cloud storage) for images and documents. I have a few questions regarding the approval workflow, machine hierarchy, and whether your existing LOTO procedures are already available in digital format. Therefore I would request we connect once so we can discuss the workflow in detail and finalize the MVP scope. Thanks, Rahul A.

Hi when it comes to LOTO, missing even one step can create serious safety risks, so having the full isolation process documented and verified on a phone makes a lot of sense. The important part here will be making the workflow simple for operators — step-by-step check-offs, photo proof, signatures, offline support, and clean export logs. I’ve worked on mobile apps involving workflow-based systems, offline sync, document generation, and user verification flows, so this type of app fits well with my experience. For an urgent MVP, Flutter would be a practical choice to move faster on both iOS and Android. To start, I’d mainly need your existing SOPs, machine isolation steps, branding assets, and any compliance rules you want followed. One thing I’d like to know will each machine have its own fixed LOTO procedure, or should managers be able to create and edit procedures inside the app? Regards, Manish P.
