@gotucat

Hi, I reviewed your request to build an iOS & Android survey app that syncs answers in real time, even with spotty connectivity, while pulling customizable survey templates via API. I’ll architect the mobile front-end with GraphQL-backed data loading, flexible User Interface / IA components for multiple-choice, open-ended text, and rating scales, and secure submission handling that prevents duplicates during offline/online switches. I’ll keep the codebase clean and maintainable, with responsive UI coverage for small and large devices, and I’ll prepare store-ready builds for TestFlight/internal testing. Let’s discuss here now.

@gutibs

Hi! This is something we can definitely handle, and the acceptance criteria you've laid out make it easier to scope this properly. Before I put a firm proposal together, the one thing I need to understand is how your existing API is structured on the authentication side — specifically whether it already exposes everything the mobile client needs (survey structure, question types, submission endpoints) or whether there are gaps we'd need to fill on the backend before the app can function end-to-end. That changes the scope considerably. On how we'd build it: we'd go with React Native, which is our standard choice for projects like this where a single, maintainable codebase needs to feel native on both platforms. For the offline/sync requirement, we'd pair it with a local queue that holds responses until connectivity is confirmed and flushes them in order — no duplicates, no silent drops. The flexible question renderer would be component-driven, so adding a new question type later is a matter of dropping in a new component rather than touching the core survey engine. Store submission, TestFlight setup and the post-approval support window are all included as you described. The rest — API integration, dynamic template rendering, signed builds — is straightforward territory for us. Happy to review the API docs and staging credentials once we've aligned on approach. Gustavo & the DoTheCode team

@Eliteinno

Hello, The difficult part is not rendering survey questions, but guaranteeing reliable synchronization when connectivity repeatedly changes. The mobile client needs local persistence, idempotent submission handling, retry logic, and clear synchronization states so answers cannot be silently duplicated or lost. A cross-platform implementation such as React Native or Flutter would keep the iOS and Android behavior aligned while allowing question types to be rendered from the backend schema rather than hard-coded into individual surveys. Store-ready builds should then be tested against the specified devices and offline/online acceptance scenario. Does the existing API already provide stable survey versioning and a unique submission/answer identifier for idempotent retries? Have a nice day

Yes. Here is a shorter version, safely under 1,500 characters: Hi, Your project is a strong fit for my mobile development experience. I would recommend Flutter to build a high-performance, maintainable app for both iOS and Android from a single codebase. The key challenge is reliable survey synchronization when users switch between offline and online connections. I can build an API-driven survey system with local persistence and a reliable sync queue, ensuring responses are not lost or duplicated. I can handle: * Dynamic survey templates loaded from your REST/GraphQL API * Multiple-choice, text, and rating-scale questions * Real-time sync with offline support and automatic retry * Unique submission handling to prevent duplicates * Secure API integration and error handling * Responsive UI across iPhone and Android screen sizes * iOS TestFlight and Android AAB builds * Clean source code, README, and initial store-support I have 9+ years of mobile development experience, including iOS, Flutter, API integration, local data handling, Firebase, and production app deployment. I’d be happy to review your API documentation and staging environment and discuss the best architecture for the survey and sync flow. Ready to get started.

@shayankhan333

Offline sync is where most survey apps quietly lose data, so I'd build the queue and retry layer before any UI. React Native with a local SQLite queue, dynamic renderer that pulls your template JSON, and signed IPA/AAB ready for TestFlight and Play internal testing. One catch: iOS kills background sync aggressively, so retries need to fire on app resume too. 1) REST or GraphQL for the template endpoint? 2) Any auth on respondents, or open survey links? Cheers Shayan
