The heart of the build is a secure user login / authentication flow (email, social sign-in, password reset) and a real-time messaging & chat module for both one-to-one and group conversations. Choose the stack you’re strongest with—Flutter, React Native, Ionic, or a well-structured PWA—as long as it delivers a consistent cross-platform UI and near-native performance. I’m happy to work with Firebase, Supabase, AWS Amplify or a comparable backend for auth and live chat as long as it stays scalable and clean. Key expectations • Clean, well-commented code committed regularly to Git • Responsive, accessible design that adapts sm...

I need a production-ready, cross-platform book-summary application delivered on a tight schedule. The experience should feel close to Headway: concise text summaries presented in a clean reading view and an instant switch to audio for users who prefer to listen. Core scope • Simultaneous releases for Android, iOS, and a responsive web app. • Secure e-mail/social login feeding a personalised dashboard that tracks reading streaks, saved titles, and listening progress. • Subscription flow with free trial, upgrade, cancel, and server-side receipt validation (Stripe or an equivalent you recommend). • Lightweight admin panel where I can upload books, edit summaries, attach audio files, set free/paid flags, and view basic user and revenue stats.

I’m launching a service-based platform similar in spirit to Urban Company and I need help turning the idea into a fully working product. The scope covers three layers: • A responsive website that mirrors the core functionality of the mobile experience. • A native mobile app released on both iOS and Android. • Ongoing IT support once the product is live. Core workflows include secure user sign-up / log-in, real-time appointment booking, and in-app payments, all tied to a clean service-provider marketplace flow. I’m open to the tech stack you’re most comfortable with—whether that’s Flutter, React Native, Swift/Kotlin with a React or front-end—as long as the final build is stable, well-documented, and easy to maintain.

I need two separate, production-ready Android APKs built from scratch. The first APK is a lightweight video editor focused purely on cutting and trimming. A clean timeline, frame-accurate scrubbing, and export in the common Android-friendly formats are all essential; effects or transitions are not required at this stage, so performance and speed on mid-range devices should be the priority. The second APK is a logo creator that ships with solid graphic design tools: vector shapes, colour picker, layer controls, and high-resolution export (PNG and SVG). I am not looking for premade templates; the power must come from the toolset itself so users can build unique logos from a blank canvas. Please write the projects in Kotlin or Java, respect current Android SDK guidelines, and deliver wel...
I already run an Open edX instance and now need the official mobile codebase compiled and branded for it. The work is straightforward: point the app to my site URL, swap in my logos, colours, and any light UI tweaks I provide, then generate release-ready builds for both Android (APK/AAB) and iOS (IPA). I will supply the design assets and the server details; you handle configuration, package-name changes, build-signing setup and a short README so I can reproduce the builds later. Once the binaries pass a quick smoke test against my staging server, the job is done. Deliverables • Updated source with branding committed • Signed Android APK/AAB + iOS IPA • README covering environment, commands and keystore/provisioning steps Familiarity with the Open edX mobile repo, And...

I need a seasoned Android developer to create a multilingual mobile app built primarily with Kotlin. Dynamic language switching is central to the project, so users must be able to move from one language to another instantly without restarting the app. While performance and scalability matter, the top-line priority is a polished, intuitive UI/UX that feels native in every supported language. The codebase should reflect current Android best practices—proper architecture components, clear separation of concerns, and thoughtful use of coroutines or similar techniques for smooth performance. If Jetpack Compose fits naturally into a Kotlin workflow I’m happy to consider it, but the core requirement is clean, idiomatic Kotlin throughout. To keep the product maintainable, please stru...

I’m bringing a new social-media experience to life and need a React Native expert who can deliver a production-ready cross-platform app for both iOS and Android. The project already has polished Figma screens and a documented REST/GraphQL backend; your task is to turn those assets into a smooth, scalable mobile product. The core scope covers three pillars: • Real-time messaging with push notifications • Rich user profiles (avatar, bio, media gallery) • An infinite-scroll news feed for text, images, and video You’ll work in TypeScript, modern React Native (current stable), and a state manager such as Redux Toolkit or Zustand. Clean navigation (React Navigation 6), offline handling, and basic analytics are expected. I’ll look for well-structured compo...
Build a lightweight Android application that lets users create an account with their email and password, log in securely, and manage a single user-profile record. Only core profile details need to be stored; you may use SQLite/Room or a small cloud option such as Firebase—whichever keeps the setup quick and reliable. The interface must feel modern, clean, and touch-friendly on every common screen size. Material Design components, smooth navigation, and clear typography are expected so the app looks polished without unnecessary visual clutter. Everything should be wrapped up within 2–3 weeks. To make hand-off seamless, I will need: • A signed, release-ready APK and a debug build for testing • The full Android Studio project with well-commented Kotlin or Java code ...
I’m ready to turn my idea into a fully functioning mobile app and need an experienced developer who can deliver native-quality performance on both iOS and Android from a single, consistent code-base. At this stage the core concept is set—I know I want a mobile application, not a web or desktop tool—yet the exact feature set still needs to be refined. Here’s what I can confirm right now: • Target platforms: both iOS and Android, released simultaneously to the App Store and Google Play. • Tech stack: I’m open to your professional recommendation (Flutter, React Native, Kotlin/Swift side-by-side, or another modern approach) as long as it yields a smooth UI, quick iteration cycles, and long-term maintainability. What I need from you: 1. A brie...
For my final-year project I need a fully functional mobile application that runs smoothly on both iOS and Android.

Core scope • Cross-platform build so a single codebase delivers native experiences on the App Store and Google Play. • Secure user sign-up/login and local data encryption. • Intuitive screens where users can log daily vitals, side-effects, and notes tied to specific medications. • Charts or simple analytics that turn those logs into easy-to-read trends. • Lightweight cloud sync so data is not lost when the device changes. I am happy for you to choose the framework you are most efficient with—Flutter, React Native...
I need a secure, centralised payment gateway that plugs straight into my mobile app on both iOS and Android. The goal is simple: let users pay with any major credit or debit card inside the app without being pushed to an external browser, while keeping every transaction PCI-compliant and tokenised for maximum security. You will design, build, and document the full stack of the gateway: backend API, merchant dashboard, and lightweight SDKs (Swift and Kotlin) that my development team can drop into our existing code-base. The service must authorise, capture, refund, and void transactions, return clear error codes, and expose webhooks so we can update order status in real time. Deliverables • RESTful (or GraphQL) API with authentication, sandbox, and production endpoints • iOS ...
I need a straightforward, good-looking mobile application that lets diners browse our restaurant’s menu—nothing more, nothing less. The app’s sole purpose is to present dishes clearly, with photos, prices, and short descriptions. There is no online ordering, no reservation flow, and no custom-order logic; I want guests to tap the app, scroll through the meals, and instantly see what we serve. Clean navigation is key. A single-level or minimally nested structure is fine as long as items load fast and look sharp on both iOS and Android. I am flexible on the underlying tech—React Native, Flutter, Swift, Kotlin, or a lightweight PWA are all acceptable as long as the final build is stable and easy for my staff to update. Deliverables should include: • Full source ...
