I need a cross-platform mobile app, built once and deployed to both iOS and Android, that lets my field team audit airport kiosks and instantly turns their answers and photos into a clean, ready-to-share proposal. Here is how the workflow should feel: • The auditor opens the app, selects the specific kiosk or location, and walks through a survey that mixes multiple-choice, open-ended, and rating-scale questions. • Skip-logic must guide them automatically so they only see questions that apply to that kiosk. • At any point they can snap pictures that are stored alongside the corresponding question and time-stamped. • When the survey is submitted, the app generates an output—preferably a PDF and an Excel/CSV—organised by kiosk with all answers, images, and a summary section I can drop straight into a proposal deck. Core functions I expect you to cover: survey creation UI, offline data capture (airports don’t always have reliable service), secure cloud sync when a connection returns, a simple dashboard to review or export completed audits, and polished layouts that work neatly on typical iPhone and Android phone screen sizes. Deliverables 1. Production-ready iOS & Android builds (TestFlight / APK + Play Console ready). 2. Source code with clear instructions to compile. 3. Admin or dashboard panel to edit surveys, download results, and manage users. 4. Auto-generated proposal/output template in PDF and Excel/CSV. 5. Short hand-off guide so my team can add new survey questions and tweak skip logic without touching code. Acceptance criteria • All question types (multiple-choice, open-ended, rating scale, photo) function smoothly with skip logic. • Exports mirror the on-screen data, including embedded images. • A single change in the admin panel reflects instantly in both iOS and Android surveys after next sync. • App passes App Store and Google Play review guidelines. If you have experience with React Native or Flutter, offline-first sync patterns, and generating dynamic PDFs, you’ll probably find this project straightforward. Let me know your preferred stack and any similar work you can show.
