## What is RelevOne?

RelevOne is a mobile app designed to simplify technical field surveys and the positioning of industrial supports.

On site, create your room or work area, define its dimensions, and position supports accurately using simple X, Y, and Z coordinates.

View your layouts from several perspectives:

• top view;
• side view;
• perspective view;
• positioning on floors, walls, or ceilings;
• dimensions and specifications for each support.

RelevOne stores your surveys directly in the app without requiring an internet connection. You can manage multiple work areas, add supports, edit or duplicate them, and keep everything organized.

The app is intended for technicians, planners, project managers, designers, electricians, pipefitters, mechanics, and professionals working in industrial, nuclear, energy, and maintenance environments.

Built for field use, RelevOne provides a clear, fast, and practical interface to reduce measurement errors and make work preparation easier.

RelevOne is a surveying and preparation aid. Technical checks, engineering calculations, and final approval remain the responsibility of qualified professionals.

Create your own technical report from your surveys, customize the project information, then export and share it with colleagues, clients, or preparation teams. All essential data is organized in a clear PDF document ready to be sent by email or any other sharing method.

Create custom mounting surfaces and supports by defining their dimensions, fixing points, and technical specifications. Save them to your personal or professional library so you can quickly reuse your most common support models when creating a new environment.
