Guide Overview ​

This guide explains the key concepts and terminology used in the Zuno Engineer App. Whether you're new to the team or need a refresher, this section covers what you need to know about how the app works from a business perspective.

What is the Engineer App? ​

The Engineer App is a mobile application used by self-employed field engineers (plumbers, gas engineers, electricians) to manage their work. Think of it as their daily companion for:

  • Receiving and accepting job offers
  • Viewing job details and customer information
  • Completing required paperwork digitally
  • Uploading photos and certificates
  • Tracking their schedule

How does it connect to the customer app? ​

The Zuno Engineer App is one half of a two-app ecosystem. While self-employed engineers use this app in the field, customers use a separate Customer App to manage their bookings and track progress.

How they work together:

  • Real-time updates: For boiler installations and services, engineers can send ETAs that appear in the customer app
  • Information sharing: Photos and specs uploaded by customers are accessible to engineers during jobs
  • Shared backend: Both apps connect to the same backend services, ensuring consistent booking details, installation progress, and customer information
  • Quality assurance: Engineer documentation submissions are reviewed by support staff before jobs are marked complete

It's a coordinated ecosystem where both apps serve their specific audience (engineers vs customers) while maintaining data consistency.

Built with Expo ​

The Engineer App is built with Expo, a framework for building React Native apps. Expo provides a managed development environment that simplifies building, testing, and deploying mobile apps to both iOS and Android from a single codebase.

Key benefits of Expo:

  • Single codebase - One TypeScript codebase for both iOS and Android
  • OTA Updates - Push bug fixes directly to devices without app store review
  • EAS Build - Cloud-based build service for creating app binaries

For information about the different types of builds available, see the Builds documentation.

  • Repair - Repairing broken equipment
  • Service - Routine maintenance
  • Callout - Emergency visits
  • Remedial - Miscellaneous work such as scaffolding, or anything that doesnt fit in the above categories
