Field Snaglist Mobile App

I need a streamlined mobile application that lets on-site technicians capture snags, attach photos, add notes, and have everything compiled automatically into a professional report I can share with clients. Core flow • Technician logs in through Single Sign-On, opens a job, snaps photos, tags each with comments, priority, and location, then saves. • When the job is closed, the app stitches all entries into a branded PDF/Excel report—photos, descriptions, timestamps, —ready to email or download. • Administrators access a web or in-app dashboard to create projects, assign technicians, and review or edit generated reports before release. Key requirements • Native performance on both iOS and Android (I’m open to Flutter, React Native, Kotlin/Swift or similar—whichever lets us keep one codebase without sacrificing camera speed). • SSO integration using OAuth 2.0 (Google Workspace / Microsoft 365). • Offline capture with auto-sync once a signal returns. • Secure cloud storage for images and data, organised by project. • Clean, minimal UI that a field tech can grasp in minutes. Deliverables 1. Source code and build instructions for iOS & Android. 2. Deployed backend (REST or GraphQL) with database schema. 3. Automatic report template (editable branding). 4. Brief user manual and hand-over session. I’ll provide sample report layouts and brand assets once we start. Please outline your proposed tech stack, milestones, and any similar apps you’ve shipped.
