React Native Jobs

I’m building an app that showcases 30 different swimming-pool models and I need a fast, reliable quote form inside it. Users must be able to enter their precise pool dimensions and pick the pool type, then receive an instant price on screen—no waiting, no extra clicks. The interface has to feel modern and sleek so it blends with the rest of the app’s UI. I’d like smooth transitions, clear typography, and responsive design that looks good on both phones and tablets. Core deliverable: a fully coded, plug-and-play form module that I can drop straight into the current project. If you prefer React Native, Flutter, or another mobile-friendly framework, let me know; I’m flexible as long as the final component is lightweight and easy for me to edit later (prices, ...

I need an end-to-end digital platform for my rental business that includes: • A responsive website • A native-quality mobile app for iOS • A native-quality mobile app for Android • A single back-office dashboard so I can add listings, update prices, and see key metrics in real time I’m aiming to keep the total build under the 60 K mark, so I value clean, reusable code and a clear milestone plan. If a cross-platform framework such as Flutter or React Native lets us ship faster without compromising quality, I’m open to it—just outline the trade-offs. Likewise, you can choose the server stack (Laravel, Node, or similar) as long as it stays lightweight, secure, and easy for me to maintain. Core acceptance criteria • Website and both apps pass...

I need a clean, fast mobile application that runs natively on both iOS and Android. The core of the build is a modern UI/UX that looks sleek, loads quickly, and feels intuitive from the very first screen. Login & Registration • Email + password flow only (social or 2-factor can come later) Beyond that, the app must: – handle data securely on device and server side, – fire push notifications or in-app alerts reliably, – remain easy to extend so new features slot in without a full rewrite. Performance is non-negotiable: smooth navigation, minimal load times, zero stutter. If you can architect a scalable codebase, design the interface, and then deliver polished builds to both stores, we’ll be a great fit. When you reply, please point me to ...

I’m setting up a brand-new online store and need both a responsive web application and a native-feeling mobile app to launch side by side. The visual direction is classic and elegant—think timeless typography, refined color palettes, and a layout that feels premium rather than trend-driven. To make sure the platform is ready for real-world transactions from day one, I need these essentials implemented and fully tested: • Shopping cart flow that can handle variants, discount codes, and guest checkout • Payment gateway integration (Stripe or a comparable PCI-compliant option) with support for major cards and digital wallets Beyond those must-haves, I expect clean, maintainable code, an intuitive admin dashboard, and deployment to both the App Store/Google Pla...

I need a cross-platform reminder application that runs smoothly on both iOS and Android. The core feature is hands-free use: I want to press one button, speak naturally—“remind me to drink water at 3 p.m.”—and have the app parse the command, schedule it, and confirm out loud or with a brief on-screen prompt. Think of the voice flow you experience with Alexa or Google Assistant; I’m after that same friction-free feel, but inside a dedicated app. Scope of the first release • Voice capture and speech-to-text using any reliable low-code or no-code tools you’re comfortable with (Flutterflow, Adalo, React Native with Expo Voice, etc.). • Time-based reminders only, with options for one-off or recurring schedules (daily, weekly, custom interval). ...

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 ready to move Catalyst from concept to a working MVP and need an experienced full-stack partner to make it happen. Catalyst will serve insurance brokers as an all-in-one operating system, replacing today’s patchwork of spreadsheets, email quote requests, and individual insurer portals. Scope of this first build The MVP must let a broker log in, create or import a client, request quotes from the major national insurers we’ll support at launch, display side-by-side comparisons, track compliance evidence automatically, and communicate outcomes back to the client—all through a single, responsive web interface that works smoothly on desktop and mobile. Core modules to deliver • Automated quoting: trigger and retrieve quotes via the insurers’ AP...

I’m ready to turn a simple idea—a clear, distraction-free task-management utility—into a polished app that lives in both Google Play and the Apple App Store. To make that happen, I need someone who can handle the full journey: coding a stable, modern tool app around core task-tracking features and then guiding it through each store’s review process until it’s publicly available. You’ll be free to choose the most sensible tech stack for a shared code-base (Flutter, React Native or another cross-platform solution are all fine with me) so long as the final result feels native on Android and iOS, meets current store guidelines, and is easy for me to maintain. Key deliverables • Production-ready Android (AAB) and iOS (IPA) builds • All required ...

I have an interactive web prototype for SafeZen—my startup that boosts cognitive performance through quick reaction-time tests and guided focus sessions—and I’m ready to turn it into a polished mobile MVP for both Android and iOS. The feel I’m after is unmistakably minimalist: clean screens, friction-free navigation and zero visual clutter. Core user flow is already validated on the web; your job is to recreate that experience natively (or with a robust cross-platform stack) while keeping the door open for future feature growth. Key functions that must ship: • Reaction-time focus test that runs smoothly on a touchscreen • Pre-recorded guided audio focus session (no user uploads in this phase) • Automatic before/after measurement and focus-scor...

The concept is similar to platforms like Airbnb or Fat Llama, but focused on renting physical items between users. The application is already built and functional. The current priority is stabilizing and refining the existing system, improving reliability and UI consistency before expanding into additional features. This project is NOT about building an app from scratch. The core product already exists. The main goal now is to strengthen the existing architecture, improve stability, and polish the user experience so the platfor...

I’m putting together a production-ready Expo starter that lets any future mobile app work completely offline first, then sync seamlessly when a connection is available.

I’m building a logistics-focused utility app in React Native and need someone who can take it from wireframes to store-ready releases. The heart of the project is two core features: real-time tracking of vehicles or parcels and smart route optimization to cut both miles and delivery times. The front end will be React Native (TypeScript preferred) so we can hit iOS and Android with one codebase. On the back end I’m open to Firebase, AWS Amplify, or a lightweight Node/Express API—whichever you can integrate quickly while keeping real-time location data flowing smoothly. Google Maps SDK or Mapbox for mapping and WebSocket or Firebase Realtime Database for live updates are likely fits, but if you have a better stack in mind I’m happy to hear it. Key points you sho...

I want to enhance my existing mobile app by adding a simple countdown timer that rewards users with in-app coins once it hits zero. When the timer finishes, I need the app to trigger a flow that prompts the user to complete a small task (for example, watching a video or website) before the coins are actually credited. Here’s how I picture it working: • When User clicks the given link timer starts and When the timer reaches zero and the task completes, the user completes that task, the correct number of coins is added to their account and reflected immediately in the FRONT-END and backend database. Key points I need you to handle: • Clean, reusable timer component using the framework already in the project. • A secure coin-crediting method that can’t be...

I need a full-featured, small-scale multi-vendor marketplace built natively for both Android and iOS. The app has to let any store—regardless of product type—open a shop front, list items, and receive orders, so the catalog structure must be flexible enough to cover clothing, electronics, home goods, or anything else vendors decide to sell. User roles the system must recognise: - Buyers - Sellers/Vendors - Admin Core flows include simple account creation, product upload with images and variants, cart and checkout, order tracking, and in-app messaging between buyer and vendor. I will also need an admin console (web or app-based) where I can approve vendors, moderate listings, manage commissions, and view analytics. Payment methods to integrate: - Credit/Debit Cards - Bank Tra...

I’m kicking off a brand-new social networking mobile app and want to start with one rock-solid cornerstone: user profiles. Your task is to design and code this core module so we have a clean, extensible foundation for all future features. Here’s what I need from you: • A fully functional profile screen where users can view and edit their photo, bio, and basic details. • Secure account creation and authentication (email, Google, or Apple—whichever you’re most comfortable implementing first). • Simple back-end or cloud setup to store and fetch profile data reliably. • Clear documentation and commented code so any developer joining later can pick up where you leave off. • A short walk-through video or call at hand-off showing how eve...

I’m putting together an all-terrain rover that pairs a Raspberry Pi 5 with an Arduino. The Arduino will sit close to the hardware, polling and driving everything from temperature-humidity probes and distance sensors to an IMU (pitch/yaw/roll, altitude, compass), ESC-PWM motor controllers, speed-over-ground tracking and battery-management read-outs. All of that raw data needs to flow up to the Pi, where it is bundled, logged and pushed over a 4 G link. The Pi also runs the user interface on an onboard touchscreen. I want that interface to launch straight into a clean dashboard with drag-and-drop style widgets so I can rearrange or resize gauges, graphs and buttons while in the field. On the software side I need: • Firmware for the Arduino that publishes every sensor value pl...

I’m building a consumer-facing mobile app whose first release will let users search, compare, and pay for flight tickets directly from their phone. The long-term vision is a single marketplace that will also handle hotel reservations, streaming subscriptions, virtual-currency top-ups, and similar services, but today’s milestone is all about flights. Scope of this phase • Cross-platform mobile app (iOS and Android) built with React Native, Flutter, or a comparable framework you are comfortable with. • Real-time flight search fed by an established API such as Amadeus, Skyscanner, or Sabre (open to suggestions). • Secure checkout that supports major cards plus Apple Pay / Google Pay. • Booking confirmation screens, e-tickets saved to the user’s pro...
