I need a skilled frontend developer to craft the UI layer of a brand-new mobile app that must run smoothly on both iOS and Android. The visual language should strictly follow Material Design so the screens feel clean, familiar, and consistent across devices. The first functional milestone is solid user authentication: email/-password sign-up, secure login, password reset, and graceful error handling. Once the authentication flow is in place, I’ll expand the scope to other features such as push notifications and in-app purchases, so clean, modular code is important. Deliverables • Complete set of Material-styled screens and reusable components. • Fully wired authentication flow calling my existing backend API. • Build files or instructions so I can compile the app...
Je souhaite développer une première version d’une application mobile exclusivement pour Android. L’objectif est simple : mettre en place une interface basique permettant aux utilisateurs de créer un compte, se connecter et se déconnecter de façon sécurisée. Portée du projet • Architecture épurée, codée en Java ou Kotlin (ou un framework hybride si la performance Android reste optimale). • Écrans essentiels : page d’inscription, page de connexion, tableau de bord vide (placeholder) pour confirmer que l’authentification fonctionne. • Stockage et gestion des comptes via une base de données locale ou un backend léger (Firebase, Supabase ou équival...
I have a Flutter app running on both Android and iOS and I need two things tidied up before I push the next release to the stores. First, the push-notification redirect is broken. A user can receive the notification, but tapping it no longer takes them to the intended screen. I need that deep-link behaviour restored and tested in cold-start, background-resume, and foreground states on both platforms. Second, I’d like a small facelift inside the app: the menu layout needs re-ordering and spacing tweaks. Colours, icons, and the rest of the UI stay as they are; this is purely a navigation-drawer update. The full Flutter source code, keystore, provisioning profile, and current store listings are ready for you. Once fixes are complete, I’ll need new signed builds uploaded through...
We are looking for an experienced South Africa–based React Native developer with strong knowledge of mobile app deployment and store management for both the Apple App Store (iOS) and Google Play Store (Android). Our mobile application is already developed and functional. We are seeking a reliable long-term technical partner who can assist with publishing, maintaining, and improving the app over time. Scope of work includes: I. Deploying new versions of the app to the Apple App Store and Google Play Store II. Managing store listings, version updates, and compliance requirements III. Troubleshooting build, deployment, and store submission issues IV. Assisting with app updates and minor React Native improvements when required V. Ensuring apps remain compatible with the latest iOS...
I’m moving quickly on a new application that must run flawlessly on Android and iOS, and—if it doesn’t stretch scope—on the Web as well. My framework of choice is Flutter, so your command of Dart, platform-specific widgets, and responsive layouts will be essential. What I expect The app should feel fast and intuitive, with a minimalist, clean interface that looks consistent across devices. Core features include secure user authentication and reliable push notifications; future modules (such as in-app purchases) can stay modular, but the initial build has to be rock-solid. Under the hood, I’m looking for well-structured, readable code, meaningful comments, and clear separation of UI, logic, and data layers so the project is easy to extend. Timeline & work...
I’m building a new social-networking experience and need someone who can own both the native Android code and the complete mobile UI/UX. The app will run only on Android and must be developed natively, so Kotlin or Java inside Android Studio is expected. Here’s what I’m looking for: • Translate my rough sketches and feature list into a full UI/UX flow—from user journeys and wireframes to high-fidelity, Material-You-ready prototypes. Figma, Sketch or Adobe XD is fine as long as the hand-off is clean. • Code the core social features natively: onboarding, live feed, profile, in-app chat, push-notification settings and a lightweight post editor. Modern architecture (MVVM with Jetpack components, or your preferred clean pattern) and performance optimisation...
I have a finished Framer website and now want it rebuilt as a full-stack codebase that can be wrapped into a mobile application for iOS and Android. I’m planning to use Strapi for the CMS layer, but if you know a faster or more scalable headless option, I’m happy to hear your reasoning and switch. The current Framer layout can be adjusted; design fidelity is less important than clean, maintainable React/ code and smooth performance on mobile. The product will act as a personal portfolio with an integrated blog, so dynamic routing, SEO-friendly metadata, and simple content editing from the CMS are essential. For the portfolio section I need: • Image gallery • Video showcase • Client testimonials Please structure the project so that these components&m...
I’m building a social-networking experience exclusively for Android and need an end-to-end developer (or team) who can take the idea from wireframes all the way to a polished release on Google Play. Here is what I expect: • Design and implement a clean, modern UI that feels native to current Android versions (Kotlin or Java is fine, Jetpack Compose welcome). • Set up the complete back-end, authentication, real-time data exchange, push notifications and analytics using tools you are most comfortable with (Firebase, AWS Amplify, custom REST—open to recommendations). • Deliver a thoroughly tested APK / AAB plus full source code and clear build instructions so I can compile future versions myself. Acceptance criteria: 1. App installs and runs on A...

I need a skilled React / developer to turn our transport control-center concept into a production-ready web dashboard. The heart of the application is live bus tracking and fleet monitoring, so every component must update in real time through WebSockets and reflect instantly on a Mapbox map. Beyond the map, I want concise graphs and charts (Recharts, D3, or similar—your call) to surface key metrics such as on-time performance, vehicle health, and route load. Route management, trip scheduling, passenger analytics, and driver behavior modules will follow the same design language you establish for the core tracking views and pull all data from our existing REST and WebSocket APIs. Essential tasks you will handle: • Build responsive pages and shared components for tracking, fl...
I am rolling out a three-part bus transport platform and need an experienced Flutter developer to own the mobile side. The overall system will eventually include passenger, driver and conductor apps that talk to my existing REST API backend, but the very first milestone is the passenger experience. Passenger app – priority scope The passenger build must ship with: • Real-time bus tracking displayed on Mapbox maps • A smooth digital ticketing flow (QR / NFC hooks already in the API) • Trip planning that pulls live route and schedule data Mapbox is the mapping SDK of choice, so solid experience with its Flutter plugin is essential. You’ll wire up push notifications for bus arrival alerts, cache data aggressively for low-bandwidth corridors, and squeeze ...

It is built with: Frontend: React Native with Expo SDK 54, TypeScript, Expo Router Backend: , Node.js, PostgreSQL Hosted on: Replit What I need: Full end-to-end testing of the app (50+ screens) Bug fixing if any issues found Production AAB build for Google Play Store Help with Play Store listing and submission Ensure app works properly on all Android devices App features: 50+ wellness tools (breathing, brain training, focus timer, eye care, etc.) Premium subscription system Adviser/affiliate dashboard Trilingual support (English, Kannada, Telugu) Gamification (XP, streaks, badges, leaderboard) Admin panel Requirements: Experience with React Native and Expo Experience wit...
I’m building , a HIPAA-compliant iOS and Android application that pulls a patient’s electronic health records in real time, listens to the appointment through the device microphone, transcribes the conversation instantly, and injects safety guidance on the spot. Whenever the dialogue reveals a potential medical collision—be it a medication, an allergy, or an existing diagnosis—the app must flag it immediately. For medication errors the first release only needs drug interaction alerts; dosage verification and duplicate-therapy checks can wait until a later milestone. After each visit the system should generate an English- and Spanish-language consolidation report that summarises the transcript, the interventions triggered, and any outstanding follow-up items. Key...

Safety & moderation (High) — AI‑assisted classifiers, human review queue, report/block UX, verified profiles. Badges & reputation (Medium) — badge rules, reputation score with decay and penalties, tie to search/visibility. Community marketplace & creator monetization (Medium) — country/city ro...
I’m ready to turn my store concept into a polished mobile shopping experience delivered simultaneously on iOS and Android. Because I chose “Both” in the platform question, I’m looking for a single, maintainable code-base—Flutter, React Native or a comparable cross-platform framework would be ideal, but I’m happy to hear your recommendation if you have strong reasoning. The goal is a complete, production-ready e-commerce app: smooth browsing, quick search, secure checkout, and rock-solid order handling. I will supply product data and brand assets; you’ll handle the technical build, clean UI/UX, and connection to a payment gateway of our choice (Stripe, PayPal, or a regional option we can discuss). Deliverables • Source code and project files ...
I need a straightforward mobile app that runs smoothly on both iOS and Android. After a secure email-and-password sign-in, the user should be able to pick from ten job-site locations; each location offers ten pre-set concrete mixes plus a simple lime / no-lime toggle and a few extra fields such as slump, air, or any “etc.” notes we decide to add later. Once the inputs are chosen, the app must automatically compile the relevant data into a clean PDF. Each location gets its own table within that document—no combining—so supervisors can flip straight to the section they need. From inside the app the PDF should be shareable via the device’s native Mail sheet; no third-party accounts required. Deliverables • React Native or Flutter source (your choice...

Estoy llevando adelante una iniciativa tecnológica reservada y necesito reforzar exclusivamente el frente móvil. El backend y la capa web ya están encaminados; tu misión será diseñar y levantar una aplicación híbrida que funcione con el mismo nivel de fluidez tanto en iOS como en Android. Busco a alguien que domine al menos un framework híbrido moderno—React Native, Flutter o Ionic son bienvenidos—y que tenga criterio para integrar APIs REST, pasarela de pago y sistemas de autenticación seguros. Valoro, además, buenas prácticas de versionado (Git), pruebas continuas y atención a la escalabilidad. Antes de compartir la arquitectura y las credenciales firmaremos un NDA. Si te interesa, en...
