The UI must be clean, consistent across screen sizes, and lightning-fast, all while following Flutter best practices for structure and readability. Core scope • Implement navigation and three foundational screens: Login/Signup, Dashboard, and Profile Settings. • Wire everything to a secure REST backend, handling authentication tokens and error states gracefully. • Use the Provider package for state management; architecture should remain extensible for future modules. • Optimise performance with responsive layouts, efficient image handling, and smooth animations. • Comment code thoroughly...
My in-house team has brought our React Native mobile app close to the finish line, but we still need an experienced developer to push it over. The remaining work is entirely on the front end: polishing outstanding features, fixing the small bugs that pop up during edge-case testing, and—most importantly—making sure every screen matches the approved Figma design pixel-for-pixel. I will continue handling the backend and API endpoints, so your focus stays on React Native UI logic, component optimisation, and any native module tweaks needed for a smooth release on both iOS and Android. Once you are done, I expect a clean codebase, updated Figma-accurate layouts, and store-ready builds for TestFlight and Play Console. If you have a strong eye for detail, know your way around React...
My mobile app—built around Google’s AI services—is already taking shape, but only on the front-end side. I have functional screens and basic flows coded in a cross-platform framework; what is missing is the server layer that ties everything together. I now need a developer who can complete the backend integration and push the finished product live on both the App Store and Google Play. Here is what’s left to do: • Connect the existing front-end to a robust backend (Firebase, Google Cloud, or another secure stack you are comfortable with). • Implement any required API endpoints so my AI features run smoothly and fast. • Configure build settings, signing, and store assets, then guide the app through the review process on iOS and Android until it ...
I’m ready to move from idea to working product on an app that lets people quickly find and book nearby Doctors and Tutors. The core flow is simple: users open the iOS or Android app, browse professionals in their area, pick an available slot, and confirm the appointment in just a few taps. The must-have features are: • Real-time appointment scheduling with calendar availability management for each practitioner • A clean ratings & written reviews section so users can make informed choices I already have the UX sketched out and can provide wireframes, brand colours, and sample data for a handful of test professionals. What I need from you is a full mobile build—native Swift/Kotlin or a robust cross-platform framework such as Flutter or React Native—alon...
My REST-based backend is live and documented; what I now need is the Android and iOS front-end that brings it to users. The apps are for the employees of a cleaning company. The product is a straight-forward app with four core capabilities • Logged in Users can see their shift plan • Users are get notified when their plan changes. • Shift plan – a simple calendar-style screen that shows upcoming shifts pulled from the backend. Already finished shifts should also be shown. • Time stamp capture – one-tap recording of start/finish times sent to my existing endpoints User authentication is required (username/password). Once authenticated, every call must tunnel through the current API layer; no extra server work is needed from your side. Feel free to build wi...
I’m ready to turn my concept, “Raghunathpur Karari,” into a full-featured Android social networking app. The goal is to create a space where users can connect, share updates, and build community around local interests. I need an experienced Android developer who can take the project from UI/UX planning through coding, testing, and final Play Store submission. Key requirements • Native Android build (Kotlin or Java) with modern Android SDK best practices. • Core social features: secure sign-up/login, personal profiles, post creation (text, photo, short video), likes/comments, and real-time notifications. • Clean, scalable Firebase or comparable backend for user auth, data storage, and push notifications. • Intuitive, lightweight interface opt...
I already have a full Figma design and a clear product flow; what I need now is an experienced Flutter developer who can translate every screen into fast, reliable code and fine-tune the app for release on both Android and iOS. The vision for the product is a simple, intuitive user experience—quick load times, smooth transitions, and no unnecessary clutter—so attention to detail and performance optimisation are critical. Deliverables I’d like to see as we progress: • Pixel-perfect implementation of the provided designs, responsive across common phone and tablet sizes. • Clean integration with our documented REST APIs and local persistence where needed. • Build, test, and release-ready packages for Google Play and the App Store, with guidance on the s...
I want to refresh my Freelancer.com profile with six separate portfolio pieces, each centred on a different mobile-app tech stack. The stacks that must be featured are Java, Kotlin, React-Native, Expo, Cordova and Swift (Flutter may appear as a supporting framework where it makes sense, but the six listed stacks lead the narrative). Every piece must follow a clean, professional look—consistent typography, balanced whitespace and a restrained colour palette—yet still feel unique to the specific technology showcased. Within each portfolio item I need three core sections: • A concise project description that explains what the app does and why that language or framework was chosen. • A short, genuine client testimonial that reinforces the quality of the work. •...
I have developed an android game and I am looking for including ad mobs (banner, interstitial and rewarded). However, ads are not coming including test ads. I need someone to help fix it. Technical expertise required - native android, cordova, javascript, html, XML, ad mob, github
I’m creating “Crois moi c'est possible”, a brand-new social networking experience that will live exclusively on Android. The goal is to give users an intuitive space to connect, share photos and short videos, chat in real time, and receive instant push notifications—everything they expect from a modern community app, wrapped in a clean Material Design interface. You’ll take the lead on end-to-end Android development, so solid Kotlin or Java skills are essential. A cloud back-end (Firebase, Supabase, or a solution you recommend) will handle authentication, media storage, and real-time data. I’m keen on scalable architecture, readable code, and smooth UI/UX transitions; if you excel at Jetpack Compose, even better. Deliverables • Fully functi...
I’m ready to turn my concept for a dedicated social-media Android app into a fully functioning product. The project is strictly mobile app development for the Android platform—no iOS component is planned at this stage—so your experience with Kotlin or Java, Android Studio, Firebase (or an equivalent real-time back end), and clean Material Design guidelines will be critical. Core idea The app should allow users to create profiles, share posts (text, images, short video), follow others, and receive real-time notifications. Think lightweight, fast, and intuitive rather than a bloated “all-in-one” network. A smooth onboarding flow, secure authentication, and an easily scrollable home feed are my immediate priorities; messaging and advanced discovery features can ...
I need an intermediate-level mobile application created from scratch for both iOS and Android. The core objective is to hand me a fully functional, well-structured codebase along with the compiled builds ready to submit to the App Store and Google Play. You are free to choose the most efficient toolchain—whether that is Flutter, React Native, Swift + Kotlin, or another framework—as long as performance and maintainability remain a priority. I will supply the UI wireframes and any required brand assets; you will turn those into a polished, responsive interface, wire up the back-end endpoints I provide, and ensure the finished product passes standard QA checks on real devices for each platform. By project close I expect the complete source code, build instructions, and a brief...
I’m planning a clean, intuitive navigation app that runs natively on both iOS and Android. The core experience should be the familiar 2-D map interface with smooth pinch-zoom and tilt, focused on one key feature: reliable turn-by-turn directions. My priority is accuracy and speed. When a user selects a destination, the route should calculate quickly, announce upcoming turns clearly (voice + on-screen), and recalculate instantly if they deviate. I’m happy to leverage MapKit, Google Maps SDK, Mapbox, or another solid framework—whichever you feel will give the best licensing terms and performance on both platforms. While real-time traffic and fully offline map packs aren’t required for the first release, I’d like the architecture to leave room for those modul...
