I need a single application that runs natively on iOS and Android while also loading seamlessly in any modern web browser. The heart of the build is a secure user login / authentication flow (email, social sign-in, password reset) and a real-time messaging & chat module for both one-to-one and group conversations. Choose the stack you’re strongest with—Flutter, React Native, Ionic, or a well-structured PWA—as long as it delivers a consistent cross-platform UI and near-native performance. I’m happy to work with Firebase, Supabase, AWS Amplify or a comparable backend for auth and live chat as long as it stays scalable and clean. Key expectations • Clean, well-commented code committed regularly to Git • Responsive, accessible design that adapts sm...
Hi, I’m looking to build a mobile app (MVP version) focused on short video content. This is an early-stage startup project, so the goal is to build a simple, scalable MVP first, and then expand. Core Features (MVP only): User login/signup Upload short videos (15–30 seconds) Scrollable video feed (smooth performance is critical) Like button Basic user profile Tech Preference: Flutter (for Android + iOS) Firebase (backend, storage, auth) Key Expectations: Experience building video-based or social media apps Ability to ensure smooth video loading and scrolling performance Clean, scalable code (this will be expanded later) Scope: MVP only (no advanced features like chat, filters, or live streaming for now) Timeline: 2–5 weeks (depending on approach) Please share: L...
I already host a complete online course that teaches people how to communicate with loved ones who have passed on. Every lesson, meditation, and set of instructions is live on the web; now I want to package that material as a revenue-generating mobile app for both Android and iOS. Core functionality • Training modules are the heart of the product, presented as sequential lessons so users unlock each topic in order. • The content mix is audio–first: guided meditation recordings and spoken step-by-step instructions pulled directly from my existing library. • I plan to integrate subscription or one-time purchase options (Google Play Billing / Apple In-App Purchase) so the app quickly becomes self-sustaining. Development approach I’d like the build to move ...
AI Behavioral System Development (Flutter / FlutterFlow + OpenAI + API Integration) Project Overview: We are developing an AI-powered behavioral analysis and prediction application that works like a human decision/navigation system. The system is built around two core API endpoints: Ask Endpoint → Handles user queries and returns AI-generated responses Analyze Endpoint → Processes user data and returns behavioral insights, patterns, and predictions The goal is to first fully stabilize and optimize these endpoints and then use their outputs to build multiple intelligent, user-facing features within the same system. Scope of Work (Complete Project): 1. Core API Integration & Debugging Fix and optimize Ask & Analyze endpoints Resolve OpenAI (GPT) API issues (no response, fai...
I already have more than forty-five developer-ready Figma screens in a minimalistic, clean style and now need them brought to life as a fast, scalable Android reseller e-commerce app. Key flows are mapped for OTP login, product discovery (home, PLP, PDP), cart, checkout and post-purchase tracking. You will wire these screens to the Cashfree payment gateway, an escrow-style seller payout module, ratings & reviews, saved addresses and a simple product-boosting feature. A lightweight web-based admin panel must accompany the app so I can manage catalogue, orders, payouts and user feedback in real time. I am flexible on the tech stack—Flutter, React Native or any modern Android-first approach is fine as long as the codebase remains clean, well-structured and easy to scale. Clear c...
I already have three Flutter apps in development—a Customer app, a Scrapyard app and a Driver app—all sharing one business flow. What I am missing is a robust, well-structured backbone that lets those clients talk to each other in real time and walk every order through its life-cycle without breaking. Here is the flow the system must respect: a customer creates an order, scrapyards bid, the customer accepts an offer and pays, the scrapyard uploads an invoice, I (as admin) approve the transfer, the order moves into execution, delivery is tracked, warranty takes effect and finally everything is archived. Your job is to provide (or fix) the backend so every one of those steps is reflected instantly across all three apps. Tech preferences are firm: Node.js for the server, Postgre...
I'm looking for an experienced FlutterFlow developer to build the front-end of a mobile app — Phase 1 only, fixed price. The backend already exists and is being handled separately, so this is a pure front-end job: 10 pages, clean navigation, reusable components, placeholder data, and a well-organised project ready for a second contractor to continue into Phase 2. No backend hookup, no API calls, no payment setup — that's all out of scope for now. What I need built: Ten pages in total: Splash, Onboarding, Pricing, Login/Sign Up, Upgrade/What You Get, Home, History, Detail, Progress, and Account. The layout should be mobile-first, with sensible tablet and web adjustments throughout. All pages should be linked and navigable, with reusable components built cleanly so t...

I’m building a full-featured Property Management System that runs smoothly on both iOS and Android. The core of the app is simple: owners or managers should be able to list a unit, open the calendar, accept a booking, take payment, and chat with the guest or tenant—all from one place and in real time. Key functions I must see working: • Property listing and live availability/booking calendar • Secure in-app payments with receipts • Built-in messaging and push notifications for guest or tenant communication A clean, modern UI is essential and the code needs to be future-proof (I’m open to Swift/Kotlin or a robust cross-platform stack such as Flutter or React Native, so pitch what you do best). You’ll connect the mobile front-end to a scalable...
I’m looking for an experienced FlutterFlow developer (or low-code mobile app builder) to help build an MVP for a location-based mobile application. The app is focused on **structured, localised user interaction within defined geographic segments** (e.g. city → sub-area), with a strong emphasis on simplicity, usability, and clean architecture. Scope (MVP): * User authentication (Firebase) * Location selection flow (multi-level: e.g. city → sub-area) * Personalised content feed based on user’s selected location * Ability for users to create posts (text-based, categorised) * Commenting system * Basic user roles (user / admin) * Push notifications (basic) Tech Requirements: * FlutterFlow (preferred) or similar low-code platform * Firebase (Auth + Firestore) * Clean d...
I need a production-ready, cross-platform book-summary application delivered on a tight schedule. The experience should feel close to Headway: concise text summaries presented in a clean reading view and an instant switch to audio for users who prefer to listen.

I’m launching a service-based platform similar in spirit to Urban Company and I need help turning the idea into a fully working product. The scope covers three layers: • A responsive website that mirrors the core functionality of the mobile experience. • A native mobile app released on both iOS and Android. • Ongoing IT support once the product is live. Core workflows include secure user sign-up / log-in, real-time appointment booking, and in-app payments, all tied to a clean service-provider marketplace flow. I’m open to the tech stack you’re most comfortable with—whether that’s Flutter, React Native, Swift/Kotlin with a React or front-end—as long as the final build is stable, well-documented, and easy to maintain. Deliverables ...

My Flutter project refuses to build on my Windows machine even though both VS Code and Android Studio already have the Flutter and Dart plugins installed. The problem seems to sit somewhere in the dependency chain—pub get throws errors and nothing will compile—but I can’t tell if it’s one troublesome package or the whole lot. What I need from you: • Connect remotely (TeamViewer, AnyDesk, or your preferred secure tool) and walk me through fixing the dependency errors. • Make sure the project opens, fetches packages, and runs successfully from both VS Code and Android Studio. • Verify that flutter doctor finishes cleanly and that the emulator or a connected device can launch the app. • Leave me with a brief summary of what was changed so I c...
I’m building a new social platform that lets users share photos and short videos while chatting in real time. The scope covers complete development for both iOS and Android, including design, backend, and production deployment.

Please submit a detailed project proposal outlining your planned archi...
I’m building a single mobile app that brings all of our college’s day-to-day operations into one place and, wherever useful, enriches them with AI. The app must launch on both iOS and Android from the same codebase. Core modules I need: • Attendance – real-time, AI-assisted face or voice recognition that records presence automatically and flags anomalies. • Management tools – timetables, notices, leave requests, fee tracking, and anything else staff already handle on paper or separate portals. • Analytics – an AI Analyzer that turns raw attendance and grade data into visual trends and early-warning insights. • Conversational support – an in-app AI Chatbot that answers questions for students, teachers, and administrators, pull...
I’m creating a cross-platform productivity tool and need a seasoned Flutter full-stack developer to carry it from blank repo to store-ready release. The app will run natively on both iOS and Android from a single Flutter codebase, so experience with platform-specific tweaks, Cupertino/Material widgets, and responsive layouts is essential. Beyond the front-end, you’ll wire the app to a lightweight yet scalable backend—Firebase is my default choice, but I’m open to another stack if you can justify the fit. Expect to implement secure authentication, real-time data sync, offline persistence, and push notifications while keeping performance tight. For clarity, here’s what I’ll use to sign off the project: • Clean, well-documented Flutter code followi...

I need a lightweight Android and iOS companion app whose only job is to capture non-identifiable analytics while the user interacts with any other apps on the device. My research focuses on “Digital Lethargy,” so the dataset must centre on two dimensions: • Precise app-usage time for every foreground session • Detailed event tracking on each screen the user visits (tap, scroll, pause length, exit) No personal identifiers, login credentials, or content payloads may be stored—just the timing, screen tags, and event metadata necessary for behavioural analysis.
