The scope is intentionally small—just two or three React Native screens targeted at Android for this first pass—so the work can be wrapped up within a couple of days. Core flow • On first launch the app asks for a mobile number & OTP based login, live location permission, and emergency contacts' details. Deliverables 1. React Native project ready to run on Android (Expo or bare, your call) 2. Clean, well-commented source with instructions to build and test 3. A quick video or screenshots proving push, in-app, and SMS alerts fire as expected Provide UI, Code, Help to publish App in Google Play Store - India market. Finish the build, ...
I’m launching a community-focused ride-sharing service and need a full-featured mobile app built for both iOS and Android. The first release must cover the essentials—real-time driver and rider tracking on a live map, seamless in-app payments, and a two-way rating system—while being architected so new modules can be slotted in later without rewrites. On the analytics side, I want a single dashboard that shows user-engagement trends, revenue reports, and detailed trip histories. Clean data exports are important; I intend to feed this into external BI tools down the line. Here’s how I see the initial milestone: • Passenger & driver apps (native Swift/Kotlin or a cross-platform stack such as Flutter or React Native—open to your recommendation) &bull...
I’m commissioning a fully-functioning mobile application that runs natively on both iOS and Android. You may work in Flutter, or go the native route with Swift for iOS and Kotlin for Android—the choice is yours as long as the final user experience is smooth, secure, and consistent across devices. You also enjoy using AI tools like Claude Code etc to speed up workflows but are capable of reviewing the core codebase, logic, security & vulnerabilties. Scope of work • Architect the app, build out core screens and flows, wire up any required APIs, and implement testing. • Package and prepare the binaries for TestFlight and Google Play Internal Testing, then guide the final store submissions. • Supply clean, well-documented source code plus a short hand-of...
I need a skilled frontend developer to enhance the UI layer of an existing mobile app that must run smoothly on both iOS and Android. While the design language should follow Material Design, there’s room for creative flexibility to improve the app's visual appeal and user experience. The new UI should seamlessly integrate with our current app framework. The first functional milestone is refining user authentication: email/password sign-up, secure login, password reset, and any necessary updates for graceful error handling. Once the authentication flow is updated, we’ll potentially expand the scope to other features like push notifications and in-app purchases, so clean, modular code remains crucial. Deliverables: • Revamped set of Material-styled screens with creati...
I’m building a single mobile and web platform where anyone, anywhere, can buy or rent any kind of property—residential or commercial. The app must feel truly global, handling multiple currencies, languages, and location formats while remaining fast and intuitive. To start, I need a complete, production-ready build that includes: • Property listings with powerful filters (price range, location radius, property type, amenities, etc.) • Secure user profiles and authentication, including social sign-in and two-factor options • An interactive map view that supports geolocation, clustering, and quick tap-to-detail navigation The interface has to be clean and modern, with smooth search and onboarding flows. Responsiveness across iOS, Android, and the web is ess...
I need an Android developer who can take my social-networking concept and turn it into a fully functional mobile app. This is a mobile app creation project aimed specifically at the Android platform. Scope of work: • Design and build intuitive Material-styled screens for user registration, profiles, post feed, and real-time chat. • Implement core social features—follow/friend system, likes, comments, in-app notifications, and basic content moderation tools. • Set up a secure back end (Firebase, Supabase, or your recommended stack) and integrate push notifications that meet the latest Google Play guidelines. • Deliver a tested APK plus full source code, ready for store submission. What I’m looking for: • Proven experience shipping Android apps, i...
I’m ready to turn an idea inspired by the Gottman CardDecks APP to a similar app but in Italian. This is the app I want to inspire to: --> only some Menus of this app, not all of them. ## Numbered list of requirements 1. **App concept and overall structure** The app should be a mobile app for couples, inspired by the general structure and user experience of the Gottman app, but limited to a specific set of features only. The full app content and interface must be in **Italian**. The design should feel warm, clear, intuitive, and clinically appropriate. 2. **Platforms and technical delivery** The app must be fully functional on both **iOS and Android**. A cross-platform solution such as **Flutter** or **React Native** is welcome, though native development is also accep...
I need a fully functional real-time stock-trading application that runs on both iOS and Android. The focus is speed and reliability: users should see market movements the instant they happen and be able to act just as fast. What must be in the first release: • Live stock prices and interactive charts streamed with sub-second latency • Instant buy/sell order execution wired to a reputable brokerage API • Secure user account management for sign-up, KYC, portfolio view, and transaction history You’ll design the UI, build the mobile front-end, integrate real-time data feeds, and set up any supporting back-end needed for authentication, push notifications, and data caching. Clean, well-documented code in a Git repo is required for hand-off to my in-house team. Ex...
I need a seasoned mobile engineer who can take full ownership of a new productivity tool and deliver polished iOS and Android builds on a short-term contract. The stack is fixed— Ionic Framework with React and TypeScript—so you should already be confident wiring up REST endpoints, crafting reusable components, and squeezing maximum performance out of Capacitor plugins. You will translate our Figma screens into pixel-perfect UIs, integrate core device features such as Camera, Geolocation, and Push Notifications, and hook the app into our back-end services. Clean architecture, strong state management (whether you favour Redux, Context API, or even Zustand), and rock-solid TypeScript typing are non-negotiable. I work from Chennai and can host you in-office; Delhi candidates are ...

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 ...
