Necesito desarrollar una aplicación móvil disponible tanto en iOS como en Android. El corazón del proyecto es la integración con redes sociales: los usuarios deberán poder iniciar sesión con sus cuentas existentes, compartir contenido dentro de las principales plataformas (por ejemplo Facebook, Instagram o Twitter) y ver sus propios feeds o perfiles enlazados desde la app. Cuento con la idea general y algunos bocetos iniciales; requiero que conviertas esos conceptos en una aplicación funcional y estable.

Quiero trasladar mi página de inventario a una app Android nativa que trabaje exactamente con la misma base de datos: ni copias, ni sincronizaciones externas, sino conexión directa para que todo cambio se refleje al instante entre web y móvil. El usuario ya ingresa en la web con su correo y contraseña, así que el flujo de autenticación debe mantenerse idéntico en la aplicación. Necesito que la app reproduzca las funciones que hoy ofrece el sitio —gestión de productos, movimientos de stock, reportes y cualquier otra vista crítica— con la misma lógica de negocio y sin perder velocidad. Si en el proceso puedes añadir notificaciones en tiempo real o mejoras de usabilidad, serán bien recibi...

Hello , I already own the WebViewGold iOS template () and have every asset ready—logos, HEX colours, icons, splash screens, , plus all URLs and metadata. Your mission is to drop in that branding, keep every WebView and push-notification feature intact, and guide the build all the way to the App Store. Here’s the flow I have in mind: • Apply the new colour scheme, icons, fonts and splash screens across the template without disturbing the existing functionality. • Update bundle ID, provisioning profiles, entitlements and any other plist settings the template needs. • Produce a TestFlight build so we can validate everything on real devices. • Once approved, use my App Store Connect account (I’ll grant access) to submit the release, handle any required ...

If they don't give written, ask them that you want to record them saying their reason and take their details like name designation contact etc. If both isn't possible, just take their details like name of person whom you met, their designation, contact, or t...
I already run a fully-functional e-commerce website and now want the same shopping experience packaged as native apps on both iOS and Android. The goal is a smooth, branded mobile experience that mirrors my current site’s catalogue and checkout flow while adding the engagement tools mobile users expect. Core functionality I need implemented: • User login & registration tied to my existing customer database • Product search with fast filtering and sorting • A secure payment gateway (the one used on the website, plus Apple Pay / Google Pay where possible) To boost retention and sales I also want: • Push notifications for promotions and order updates • Wishlist / favourites so shoppers can save items • Real-time order tracking inside the a...
I want to launch an Android-only mobile application whose core purpose is blogging so I can share lessons and insights from my online classes with students. The must-have capabilities for this first release are a smooth post-publishing workflow (text, images, short videos) and built-in shareability that lets readers pass any article straight to their social-media apps with a single tap. You are free to choose the tech stack—Kotlin, Flutter, React Native, or any modern Android-friendly framework—as long as the final APK is stable on current versions of Android and the codebase is clean and well-documented. A lightweight backend or Firebase setup for storing posts is fine; I simply need to create, edit, and delete articles from an admin side and have them display instantly for...
我计划启动一款跨平台移动应用,希望从软件架构设计到首个可运行原型都由同一位开发者完成。 核心需求 • 应用类型:移动应用,需一次开发同时覆盖 iOS 与 Android。 • 开发框架:对 React Native、Flutter 或 Ionic 都持开放态度,只要能充分体现性能与可维护性,可由你提出技术选型方案。 我需要的交付物 1. 总体架构设计文档——包含目录结构、状态管理方案、第三方服务集成思路与未来扩展的考虑。 2. 核心功能原型——能够在 iOS 与 Android 真机运行,展示主要页面跳转及数据流。 3. 简洁的技术交接说明——说明构建步骤、依赖版本与后续继续开发的注意事项。 理想的你熟悉跨平台框架优势与局限,对移动端性能优化、包体大小控制及商店上架流程有实际经验。如果可以在沟通中分享你之前的类似作品,将有助于我快速决策。
I’m launching an online evangelic radio show and need the full technical and production framework put in place. The station will broadcast twice a day—one slot in the morning and another in the evening—so the system must make daily scheduling effortless and reliable. Broadcasts must be live, not simply pre-recorded, because listener call-ins are central to the program’s ministry style. I therefore need an integrated call-in workflow: a phone or VoIP bridge that lets listeners join the conversation on air, with basic screening and mute controls to keep everything smooth and secure. While live interaction is the priority, I would also like each show automatically recorded for later editing and archive purposes. You may choose the streaming stack—, Icecast, S...
I’m turning a concept into a working mobile application that runs natively on both iOS and Android. The very first milestone is to set up a clean, maintainable codebase and wire in secure email-and-password authentication. I’m flexible on the tech stack—whether you prefer Flutter, React Native, Kotlin Multiplatform, or another cross-platform framework—so long as the result feels native, performs smoothly, and can be extended easily. Deliverables • Single codebase compiling for iOS and Android • Onboarding flow: sign-up, sign-in, password reset, session persistence • Placeholder home/dashboard screen ready for future features • Well-commented code pushed to my private Git repo with clear build/run instructions I’ll consider the ...

I need a complete safety-management app built with a no-code platform and delivered as soon as possible. The core piece is an ATS digital form with an integrated hazard matrix, because that module will drive most of my daily operation. My team also issues three kinds of work permits—Altura, Eléctricos and Confinados—so the tool must create, route and store each permit with digital signatures and automatic PDF output. Beyond permits, the same environment should let me: • Run mobile inspections that accept live photo uploads • Host toolbox talks with participant signature capture • Keep certificates, medical exams and ARL documents in order, with expiry alerts • Generate branded PDF reports automatically • Offer an audit-ready dashboard f...
I want to launch a cohesive suite of AI-powered creation tools that runs smoothly in any modern browser and ships as a companion iOS/Android app. The platform will revolve around four core experiences: • Chatbot: A conversational assistant driven by a large language model (OpenAI GPT-4, Claude, or a comparable open-source model) with memory, retrieval-augmented generation, and an admin panel so I can refine prompts and monitor usage. • Image & Video Generator: Text-to-image and text-to-video pipelines using Stable Diffusion / Stable Video Diffusion (or a stronger alternative) with prompt weighting, negative prompts, and upscaling. • 3D Image Generator: Generation of glTF/OBJ assets ready for WebGL display, including basic texture baking. • AI-Assisted Video E...
I’m creating a Swift-based Sudoku app whose primary mission is to teach people how to crack puzzles rather than simply letting them play. I already have the general UI vision; what I need now is a developer who can write the underlying Sudoku engine and weave in an engaging learning layer. Core objectives • Generate valid Sudoku boards on demand, analyse the current grid in real time and expose every classic solving technique (singles, pairs, X-Wing, etc.) through a clean API. • Provide instructional modes—contextual hints & tips —triggered by the user’s choice or by their mistakes. • Cover the whole spectrum of difficulty: beginner, easy, intermediate, tough and devious. Internally I’d like five granular levels, so please make the lo...

I’m ready to turn my online store idea into a full-featured mobile shopping experience that works flawlessly on both iOS and Android. The app’s single goal is clear: let customers browse products, purchase securely, and track their orders from their phone. Here’s what I need from you: • End-to-end mobile development (code, UI, and basic QA) for the two platforms • A clean product catalogue with search, filters, and a simple checkout flow • Integration with at least one mainstream payment gateway plus order confirmation e-mails/push notifications • Secure user account creation, sign-in, and profile management • Source code, build files, and brief hand-off documentation so I can maintain or extend the project later Feel free to recommend w...
I’m building a fitness-focused mobile app where nutritional guidance is front and center. The first release revolves around an accurate, easy-to-use calorie tracker: users should be able to search foods, add custom items, scan barcodes, and instantly see daily calories and macro breakdowns. Clear, attractive charts that visualise trends over days and weeks are essential so people can spot patterns and stay motivated. My priority is a solid MVP that does the following: • Smooth onboarding and profile setup (age, weight, goals). • Fast, reliable calorie tracking with an up-to-date food database and offline caching. • Dashboard summarising daily intake versus goal, with simple colour coding for “under”, “on target”, or “over”. ...
I’m ready to build a dedicated parcel-only delivery service and need a full mobile solution that runs smoothly on both iOS and Android. Core functionality must include: • Real-time driver and package tracking so users can watch their parcel move on the map • Push and in-app delivery notifications at each status change • Instant chat between customer, driver, and support to resolve issues on the spot A clean customer app, a driver app with route optimisation, and a simple web-based admin panel for order management will round out the system. Code should be written with future scalability in mind (React Native or Flutter are both fine) and integrate with standard mapping and push-notification services. Please outline your preferred tech stack, an estimated time...
I need a senior-level Flutter engineer (5 + years hands-on) to take charge of a peer-to-peer mobile application that must run seamlessly on both iOS and Android from a single codebase. The core job is to own feature development end-to-end: architecting clean Dart code, wiring up real-time data flow, refining UI components for multiple screen sizes, then shipping fully tested builds to the App Store and Google Play. The project already has a high-level product roadmap; you will turn that vision into production-ready widgets, state management (Bloc or Provider is fine), secure API integrations, and smooth animations. Regular collaboration with our designer and back-end team happens in Slack and Jira, with code reviews in Git. I release milestones every two weeks, and each sprint should clos...
I have a fully working Match-3 core in Unity and now need a seasoned developer who can wrap a persistent meta layer around it. Here is what the first release of that layer must do: • Award experience every time a player finishes a level and grant bonus XP when they post a particularly high score. • Track the running total, handle level-ups, and trigger new abilities or power-ups the moment a threshold is crossed. • Keep all data durable (local save plus cloud ready) so the loop survives reinstalls and is easy to tune through live updates. • Leave the underlying swap-and-match gameplay untouched—your work sits beside it, not inside it. • Use placeholder UI where needed; architecture, logic, and scalability matter more than visuals right now. The co...

I’m building a small showcase app for a school contest and need a polished Android solution that makes printed text friendlier for students with dyslexia. The flow is straightforward: the user opens the camera, points it at a page, and the app instantly recognises the words (OCR). As soon as the text is captured, each word is spoken aloud in sequence while that same word is highlighted on-screen in real time. The result should feel like a karaoke-style guide that lets the reader follow along word by word without losing their place. Must-have fundamentals • Android only — Kotlin or Java is fine, as long as it runs smoothly on common mid-range phones. • Real-time OCR (Google ML Kit, Tesseract, or any on-device library you prefer) with no dependency on an active int...
I’m looking for someone who can set up and run Sintra AI to help manage my social media alongside SocialBee. Important: I do NOT need an app built. I need social media management + automation.

I already have a verified D-U-N-S number for my company, but we still lack both an organizational Apple ID and an Apple Developer Program account. I’d like step-by-step help getting these two items in place so my team can finally submit both iOS and macOS apps to the App Store.

I need a full-featured ride-sharing and pooling application built for both iOS and Android. The service is designed around shared trips only, so every screen should guide users toward combining routes rather than booking a private cab. For riders I must see live vehicle locations on an interactive map, smooth in-app payments (card, wallet, Apple Pay/Google Pay, etc.), and the chance to rate and review every completed journey. Drivers, on the other hand, should receive pooled-ride requests in real time, view the optimal pick-up order, navigate turn-by-turn, and track daily earnings from an in-app dashboard. A separate administrator panel will let me onboard drivers, monitor live trips, settle disputes, push notifications, and export ride analytics. Deliverables • One codebase (...
