The core objective is to take the UI/UX I already have in mind and translate it into efficient, well-structured React Native code, integrating any necessary native modules along the way. You’ll be responsible for: • Creating the complete React Native project structure, wiring up navigation, state management, and theming. • Implementing screens and reusable components from my designs. • Connecting REST/GraphQL APIs and handling data caching, offline support, and error states. • Testing on real devices and emulators to ensure consistent performance across iOS and Android. • Preparing builds for TestFlight ...
I’m expanding our in-house team on a new mobile application that will be released simultaneously on iOS and Android and built entirely with Flutter. The core codebase, initial architecture, and design system are already in place; what I need now is dependable developers who can take full ownership of individual features, work against clearly defined milestones, and keep the codebase clean, well-documented, and test-covered. How we work • Weekly review calls and a shared Kanban board keep progress transparent. • Every task ships with unit / widget tests and concise in-line documentation. • Pull requests are peer-reviewed; merge only after CI passes. • We iterate in small increments so ownership of a story is obvious and measurable. Typical responsibilitie...
I have a concept ready for a brand-new mobile application and need it built natively for both iOS and Android—or via a robust cross-platform stack such as Flutter or React Native if that proves more efficient. The core of this job is the complete development cycle: polishing the UX/UI from my wireframes, writing clean and well-documented code, integrating required APIs, and preparing the builds for App Store and Google Play submission. When you respond, the single most important thing I need to see is past work that demonstrates you have taken an app from idea through launch. Links to live apps, GitHub repositories, or short videos of features in action will help me understand your style and code quality. Once we agree on the scope, I’ll share the full feature list and any br...
I already run a fully-functional website and now want it packaged into polished native apps for both iOS and Android. The look, navigation flow, and existing back-end logic should carry over seamlessly, but with the responsiveness and smooth interactions users expect on mobile. The single must-have feature is a secure, fully tested payment gateway. Whichever stack you prefer—Swift + Kotlin, React Native, Flutter, or another proven toolset—is fine as long as the end result is accepted by the App Store and Google Play without red-flags and the payment flow passes their review guidelines. Deliverables: • iOS and Android builds ready for store submission • Payment gateway integrated and sandbox-tested end-to-end • Source code and concise setup/build instructi...
I’m building a cross-platform food ordering experience and need a React Native developer who can take it from idea to store-ready builds for both iOS and Android. The essentials are straightforward: • Secure user registration and login • Smooth food‐selection workflow with a cart, checkout, and integrated payment gateway • Real-time order tracking so customers can watch their meal move from kitchen to doorstep Clean, modern UI components, well-structured state management, and clear commit history are must-haves. I’d like the final hand-off to include the full React Native source, build instructions, and testflight / apk release candidates so I can run final QA on my devices. If you’ve shipped similar apps and can demonstrate reliable live-tracking imp...
I have a single React-Native app with a built-in calling feature. Right now, when a notification arrives and the app is in the foreground everything works, but if the app is in the background—or worse, killed—tapping the notification no longer routes the user to the correct “calling” screen on either iOS or Android. What I need • One seamless navigation flow that works automatically from every app state: foreground, background, and fully killed. • Support for both remote push notifications (FCM/APNS) and local in-app notifications that the calling module might raise. • Automatic deep-link style routing straight to the relevant screen the moment the user taps the notification—no interim prompts or previews. Current stack highlights re...

I am building FLUX, a unified mobile marketplace aimed at French-speaking West Africa, with initial roll-out in Burkina Faso (+226). The goal is to let users open the app, browse a hierarchical catalogue—starting with Business & Finance services—configure what they need, see dynamic pricing update in real time, open a service ticket, follow its progress through push notifications, and complete payment through automatically executed USSD codes. The app must run smoothly on both iOS and Android. Whether you work natively or use a cross-platform framework is up to you, as long as the final experience feels identical on each platform and is store-ready. Key deliverables • Fully functional iOS and Android builds that pass store submission checks • Clean, well-doc...
I want to bring a new social experience to both iOS and Android through a single hybrid build. The core of the project is a fully-functional user-profile system: people must be able to register, log in, create a rich profile (photo, bio, basic details), edit it later, and browse or search for other members. Because we are targeting a hybrid stack, please pick a framework you are comfortable with—Flutter, React Native, Ionic, or a similar cross-platform tool—so long as the end result feels native on each platform. I will need the full source code, compiled builds for the two stores, and a concise read-me on how to run the project locally, rebuild, and push updates. Acceptance criteria • Smooth onboarding with email or social sign-in • Profile creation/editing persi...

A streamlined productivity app centered on task management needs to be built from the ground up for both iOS and Android. Core flow is simple: users create a task, set priority and due date, receive timely reminders, then mark the task complete. Fast, intuitive interaction and a clean interface matter more than feature bloat; note-taking and calendar integration are on the roadmap but not in this initial scope. Architecture & tech are flexible as long as end users experience a fully native look and feel—whether you choose Swift / SwiftUI and Kotlin / Jetpack Compose, Flutter, or React Native is up to you, provided performance, offline persistence, and push-notification capability meet modern standards. Acceptance criteria • Tasks can be added, edited, reordered by drag-a...
I’m building a full-featured e-commerce application dedicated to Android and need a developer who can turn the concept into a polished, production-ready app. The core objective is simple: let users browse products, add them to a cart, and check out seamlessly from their phones. Here’s what I have in mind: • A clean, modern UI that feels native to current Android design guidelines. • Product catalogue, search, filtering, and detailed product pages. • Secure account creation and login (email, social, or phone). • Shopping cart, order summary, multiple payment gateways, and order tracking. • Push notifications for promotions, order status, and abandoned carts. • An admin-friendly back-end or API integration so inventory and orders stay in s...
Project will be 15 days installments of 50USD until 4 months and 400USD. But it can get to 750USD and cross the 400USD initial budget. But 15 day installments of 50USD are fixed. I want a full team, even if it's going to use one developer. I need a revolutionary app using React Native for Android, iOS, Web and Desktop (webview but Mac and Windows App). The app is about Instagram, but with new more elements than today's original instagram. You can browser the web. You can play inside it. Why? Because it is a mix and includes banking, Google Chrome, Instagram, and WhatsApp all inside it. It looks exactly the same as Instagram today. But it is more turbo. Like, in the mobile version, it has a bottom bar for AI questions. Like Gemini. Imagine the app like you can use Instagram, Ge...
I need a revolutionary app using React Native for Android, iOS, Web and Desktop (webview but Mac and Windows App). The app is about Instagram, but with new more elements than today's original instagram. You can browser the web. You can play inside it. Why? Because it is a mix and includes banking, Google Chrome, Instagram, and WhatsApp all inside it. It looks exactly the same as Instagram today. But it is more turbo. Like, in the mobile version, it has a bottom bar for AI questions. Like Gemini. Imagine the app like you can use Instagram, Gemini/ChatGPT, Excel, Word, WhatsApp all inside it. So it will need documents and table creation. It will include all worlds main apps inside it. But it looks exactly the same like Instagram because think... the 2 billion people from Instagram will...
I’m building a SaaS platform in Bubble that must work flawlessly on the web and as native apps for both iOS and Android. The system needs three distinct login tiers—Owner, Trainer and Member—with airtight role-based permissions. Besides secure authentication, each role will access its own performance-tracking dashboards, so real-time data updates are a must. I favour a clean, minimalistic look: plenty of white space, a restrained palette and smooth micro-interactions that feel native across all screens. Key deliverables • Bubble project with responsive pages • Wrapped mobile builds ready for App Store and Google Play submission • Clear documentation of the database, role settings and performance-tracking workflows • WhatsApp API connection Ac...
I’m putting together a web-based game hub that is designed exclusively for mobile visitors and supports single-player titles only. The core of the project is a lightweight, touch-friendly site that loads fast on phones and holds at least one fully playable game on launch day. Front-end and UX Everything has to feel native on small screens, so expect responsive layouts, thumb-reachable controls, and smooth orientation changes. I’m fine with traditional HTML5/CSS/JavaScript, React, Vue, or a similar stack—the key is clean, maintainable code that performs well over typical 3G/4G connections. Game build & integration The first game can be created in Phaser, Unity WebGL, or straight Canvas/JS as long as it runs in current iOS Safari and Android Chrome without an extr...
Je souhaite faire développer une application mobile installable sur iOS et Android. La fonctionnalité essentielle est un système de paiement sécurisé afin que les utilisateurs puissent acheter directement depuis l’app. Je fournis déjà le logo, la charte graphique et le parcours utilisateur ; nous pourrons affiner ensemble l’interface si nécessaire. Ce que j’attends : • Développement natif ou cross-platform (React Native, Flutter, ou technologie équivalente) garantissant de bonnes performances. • Intégration d’un module de paiement – Stripe, PayPal ou autre solution conforme aux normes de sécurité actuelles (SSL, tokenisation). • Vérific...
