I’d like to acquire a complete, production-ready Android voice chat application. My priority is group voice chat, and the build must already include admin controls (e.g., the ability to mute, remove, or otherwise manage participants within a room).

I need a cross-platform mobile app for iOS and Android that pulls in live service-request calls and gives my field employees everything they need to handle those jobs from their phones and if possible the service requests are linked from the call center where the actual requests are registered. The core workflow is simple: a request comes in, the assigned technician is notified, the task is managed through to completion, and a clear record is stored for future reference. Deliverables • Service request notifications – real-time push alerts the moment a new call is logged. • Employee task management – accept, start, pause, update status, add notes or photos, and mark complete. • Service history log – searchable timeline showing past calls, dates, actions...
I need a complete mobile application that lets someone living abroad type in the groceries their relatives back home need, then share that list instantly and make a purchase and deliver it to their family. The build has to run smoothly on both iOS and Android, using a single code-base if it keeps costs and maintenance in check. Core functions I must see working: sign-up / sign-in for every user, real-time sharing of shopping lists between paired accounts, and a simple chat window so family members can ask questions such as quantity, brand preference, or price confirmation without leaving the app. One language is fine for the first release, but I want the architecture clean enough that translators can be plugged in later. For hand-off, please provide: • Source code for iOS and ...

I need a fully functional mobile application released on both Android and iOS stores. Although the exact vertical is still being finalised, a few must-have features are already clear: • Secure user authentication (email, social, or phone-based—whichever you recommend) • Real-time push notifications delivered reliably on both platforms • Seamless integration with a third-party analytics tool so I can track events, funnels, and retention from day one You will handle everything from setting up the codebase and configuring the analytics SDK to preparing production-ready builds for Google Play and the App Store.

I’m planning to roll out a lightweight, Connecteam-style application whose sole focus is clear, reliable task management. The core build has to cover three essentials from day one: • Assignment tracking – every task must be linked to an owner, with status changes logged in real time. • Progress reporting – I need an at-a-glance dashboard that aggregates task status and completion percentages. • Due-date reminders – push, email, or in-app notifications when deadlines approach or slip. Clean UX is key; the fewer taps it takes to create, assign, and update a task, the better. I’m open to your preferred stack—whether you lean React Native, Flutter, or a straightforward web PWA—so long as the final product is responsive and easy...

I’m planning a straightforward but polished utility app that runs natively on both iOS and Android. The core idea is simple: give users a handy tool they can open, complete a single task quickly, and move on. Think of a flashlight or unit-converter level of simplicity, yet executed with modern design, smooth performance, and zero clutter. Here’s what I need from you: • Build a single codebase that compiles cleanly for iOS and Android. I’m open to Swift UI + Kotlin, Flutter, React Native, or another framework you’re comfortable with—provided the final packages meet each store’s requirements. • Craft a minimal UI that looks at home on current-generation devices, respects dark mode, and scales from small phones to large screens. • Integ...
I want to enrich my existing mobile app with a dedicated beauty and makeup section. The core requirement is that everything lives natively inside the app—no webview shortcuts—so users enjoy the same polished experience they already know. At this stage I’m flexible on the exact format of the feature. A real-time virtual try-on powered by AR, swipe-through step-by-step tutorials, or AI-driven product recommendations could all work; what matters is that the final solution feels intuitive, visually impressive, and quick to load on both iOS and Android devices. I’ll lean on your expertise to help identify which approach best matches user expectations and technical feasibility. Key deliverables • Discovery session and short proposal outlining the chosen concept, ...
I have a clear concept for a new app and need a developer who can take it from idea to launch on both iOS and Android. The core of the first release will include: • Secure user profiles with photo, bio, and basic settings • Real-time AI chat • A scrolling news feed that supports text, image, and link posts I’m open to the framework you prefer—whether that’s React Native, Flutter, or native stacks—as long as the final build is stable, well-documented, and ready for App Store and Google Play submission. Here’s how I picture our workflow: 1. Map out an MVP feature list and milestones. 2. Build and test each module in weekly sprints, sharing progress on GitHub. 3. Iterate on UI/UX and performance until both apps meet release criteri...
I need a developer who can take my idea for a flashcard-based productivity tool and turn it into a polished application that runs smoothly on Windows laptops, Android phones/tablets, and iOS devices. The app’s learning engine must rely on active recall and spaced-repetition algorithms to help users retain information efficiently. Core experience I’m after • Create, edit, and organise decks and individual cards (text first; images and audio later as a plus). • Automated scheduling of reviews driven by spaced-repetition logic. • Quick-review mode for on-the-go study sessions. • Real-time progress tracking with simple statistics. Cross-platform requirements The same account and data should sync seamlessly between Windows, Android, and iOS without the us...

I need a complete mobile application that showcases our property listings, manages client interactions, and offers immersive virtual tours—all in one place. The goal is to give buyers and renters the ability to browse, filter, and bookmark homes while allowing my sales team to track inquiries, schedule showings, and follow up, directly from their phones. Key points you should know: • Platform coverage: I want a single code-base deployment for both iOS and Android. • Core features: searchable listings with photo galleries, in-app chat or lead capture for client management, and 360° or video-based virtual tours embedded per property. • Admin control: a web or in-app dashboard where we can add/edit properties, upload media, and view client analytics. • S...

Type: Fixed-price project (with option to extend into ongoing QA) Category: Mobile QA / Manual Testing Duration estimate: 1–2 weeks Overview We have a Flutter mobile app (Android + iOS) for a sports-coaching marketplace — athletes book sessions with coaches and academies, three user roles (Athlete, Coach, Academy) plus an Admin panel, real backend and real data. Basic QA is already done in-house — core happy-path flows (signup, browse, book, cancel, basic profile edits) have already been tested and are working. We do not need someone to click through the obvious flows again. We need an experienced QA tester who can find the bugs that basic testing misses: edge cases, race conditions, concurrent-user scenarios, partial/malformed input, boundary conditions, and the kind ...
I have already laid down the core of OpsFlow—a Flutter / Dart front-end, Go REST back-end, PostgreSQL database, and a Docker-based deployment stack complete with MinIO object storage, role-based auth, notifications, audit logs, and automated health checks. For the very first public release I want to polish and ship a solid work-order workflow. The scope for this milestone is focused and clear: enable streamlined “work-order creation and assignment” from end to end. What you will find waiting for you • A clean Flutter UI skeleton and shared component library • Fully documented Go micro-services with CRUD scaffolding in place • Auth, user, asset, and inventory tables already seeded in PostgreSQL • Docker-compose scripts for local orchestratio...
I want to launch a real-time chat application that feels as familiar as WhatsApp but removes the paywall entirely and runs everywhere—iOS, Android, and in the browser. The core experience must cover one-to-one and group messaging with the same speed and reliability users expect from a modern messenger. No authentication is required; users should be able to open the app and start chatting instantly. If a lightweight, automatic identifier is needed under the hood (for encryption or routing), build it in transparently so the end-user never sees a sign-up screen. Because this project targets three platforms at once, I am open to React Native, Flutter, or any other cross-platform toolkit that can compile cleanly to mobile and web while sharing a single codebase. Real-time transport and ...
Hello Sir, lets continue the project. place bid to discuss more in chat
I’m ready to commission a full-featured education app and admin panel built in either Flutter or React Native. The student-facing side must present a simple, clean interface while packing in everything today’s learners expect: • Student sign-up / login • Recorded-video courses with smooth streaming • Live-class rooms (integrated scheduling & reminders) • PDF notes, downloadable or in-app view • Mock tests and quizzes with scoring • Course purchase flow tied to Razorpay / UPI for secure checkout • Push notifications for new lessons, live-class alerts and offers • Student profile with progress tracking On the admin side I need the tools to run the entire academy: • Upload and manage recorded videos & PDF...
I want to build a full-featured parcel-delivery application that offers the same seamless experience Porter gives its users, but tailored to individual packages rather than full-truck moves. The core of the project is a single code-base that ships to iOS, Android, and a responsive web portal, so customers can create consignments wherever they are. Key user flows are straightforward: a sender opens the app, enters pickup & drop-off details, sees live price estimates, pays on the spot, and then follows the courier in real time on an in-app map until delivery is confirmed. For this to feel truly “Porter-like”, the real-time tracking must be granular, the payment gateway must settle instantly, and every customer—new or returning—needs their own secure account with ...

I’m Pania Rameka, creator of InvestHER, and I’m ready to turn my vision of a supportive, education-rich trading space for women into a fully functional mobile app. Core purpose The app’s heartbeat is community engagement. I need a set of discussion forums where members can openly share ideas and experiences around: • Investment strategies • Market trends • Personal finance management The forums must feel intuitive, safe, and inspiring. Think clear thread hierarchy, quick search and tagging, the ability to follow conversations, gentle gamification for participation, plus robust moderation and reporting tools so the tone always stays constructive. Surrounding experience Alongside the forums I want embedded financial-education content—arti...

At SKYCA DIGITAL PRIVATE LIMITED I manage a constant flow of AI-centred SaaS, web, and mobile builds and want to expand our bench with developers and designers who can take full ownership of features, sprints, and occasionally entire products. Current pipeline highlights • AI-powered modules that blend OpenAI, TensorFlow and Hugging Face models with existing business logic. • Green-field and refactor projects across the full stack—React or on the frontend, Node.js, Python or PHP services on the backend, all containerised with Docker and deployed to AWS or GCP. • Flutter-based mobile apps that share code with React Native components when practical. • Robust data layers on MySQL and MongoDB, exposed through well-documented REST APIs. How we’ll work ...
Category: Mobile Phone / Web / Software Architecture Skills: iOS Development, Android Development, React Native, Flutter, SEO, Mobile App Development, Full Stack Development Project Overview We are looking for a senior, experienced developer to take an existing social media platform, PRYLINK, from its current build on Lovable and turn it into a fully native mobile experience for both iOS and Android. This is not a one-off job — we have multiple projects in the pipeline and are looking to build an ongoing working relationship with the right person or team. PRYLINK is a social media platform. The current version was built using Lovable, and we now need a native mobile app (iOS + Android) with the same core functionality, plus strong Google SEO and marketing support to help it grow....
Hola, bendiciones. Estoy buscando un desarrollador senior en Flutter + Firebase para crear una aplicación cristiana completa con videollamadas, comunidad, cursos, chat y contenido espiritual. Quiero un diseño profesional y una arquitectura sólida. ¿Puedes enviarme tu portafolio y un precio fijo para este proyecto? Gracias.
I need a brand-new mobile application built for both iOS and Android, delivered as a single, cohesive code-base that feels completely native on each platform. All core features and user flows are already mapped out on my side; I will pass along wireframes, a detailed functional specification, and brand assets as soon as we kick off. The job covers the full life-cycle: refining the technical architecture, crafting a polished UI, coding the front-end and any required back-end services, thorough QA on real devices, and finally shepherding the builds through App Store and Google Play submission. A modern cross-platform stack such as Flutter, React Native, or another comparable solution is perfectly acceptable—feel free to advocate for the approach you believe will give the smoothest per...
Hola, requiero contratar a un profesional o equipo que pueda proveer 20 probadores (testers) con dispositivos Android para cumplir con el requisito de prueba cerrada de Google Play Console para mi aplicación en Flutter ("Acarreos y Servicios"). Requisitos: 20 Testers Únicos: Deben ser 20 dispositivos Android y cuentas de Google reales distintas (no emuladores). 15 Días Consecutivos: Los 20 testers deben unirse a la prueba cerrada a través de nuestro enlace, descargar la aplicación y mantenerla instalada en su teléfono móvil durante 15 días seguidos.

I want a clean, intuitive mobile application that lets people record or choose professional-grade videos on their phone and upload them straight to the cloud. The build must run smoothly on both Android and iOS, with a single code-base preferred for easier maintenance. Key flow • The user pays Rs. 10 to download the app from Google Play (I’ll set the same price on the App Store). • After a quick sign-up, each user gets a personal profile page that lists their uploaded clips. • Viewers can watch a video, tap Like, or leave a comment. • All uploads should stream reliably on common mobile data speeds; feel free to suggest a cost-efficient storage/CDN combo such as AWS S3 + CloudFront or Firebase. Under the hood – Modern cross-platform stack such a...
I need a Flutter release engineer who can take our two existing apps all the way to production using the runbook in RELEASING.md. My immediate focus is getting clean, reproducible builds into TestFlight and the Play Console, then approved in both stores. All signing files, store listings, and Codemagic workflows already exist, so you’ll be working with ready-to-use assets while strictly respecting App Store and Play Console regulations. Once the stores are squared away, I want the subscription flow fully stable on both platforms. In production the Razorpay and Apple IAP renewals aren’t granting entitlements, subscriptions sometimes flip to past_due, and the cancel / re-enable path is unreliable. I expect an end-to-end test matrix that proves billing, server receipt validation,...
I’m building a subscription-based, white-label SaaS where every retailer receives a fully branded Android and iOS app plus its own cloud workspace. From a single super-admin dashboard I want the power to spin up unlimited tenant apps, set their plans, and monitor usage, while each retailer manages day-to-day operations in a private admin panel. Core scope • Multi-tenant architecture that isolates data yet runs on one codebase. • Role-based access control: Super Admin → Retailer Admin → Customer. • Flutter front-end for customer-facing mobile apps and retailer web panel. • Backend in either Laravel or Node.js with REST/GraphQL APIs, real-time notifications, and secure multitenant DB design. • Features per tenant: customer login, inventory,...
I’m building a cross-platform mobile app that pairs a clean chat interface with an AI-powered assistant. The goal is to release on both iOS and Android from a single code-base (React Native, Flutter, or any modern alternative you’re comfortable with). Core scope The chatbot must reliably answer our FAQ set and deliver smart, context-aware recommendations to users. I don’t need booking or reservation handling right now, but the architecture should be flexible enough to bolt that on later. I’m still deciding whether we’ll launch in multiple languages, so please set up the project with localisation hooks (string files, language switch logic, etc.) to keep that door open. Tech expectations OpenAI or a comparable LLM is the likely engine; retrieval-augmented ...

I run Kraple Fresh, a wholesale vegetable supplier, and I need a straightforward mobile solution that lets my B2B customers place orders quickly and track them with zero confusion. The app must run on both Android and iOS, present a clean, minimalistic interface, and allow users to locate produce simply by typing the vegetable name. Core functionality I’m expecting: • Secure mobile-number login and self-registration with profile editing • Product catalogue showing name, price per kg / bunch, and an image for each item • Easy cart and checkout so customers can create orders, view order history, and see real-time status updates (Pending, Processing, Delivered) • Push notifications for order confirmation and every status change • Delivery module where...
Settings Screen Concept (Flutter Mobile/Web) Keep it dead simple and powerful — one scrollable page the owner opens from the main menu. Clean cards or expandable sections so it doesn’t feel overwhelming. Top bar: “Feature Modules” with a search bar + “All On / All Off” quick toggle (with confirmation). Then grouped sections: Core Operations (always on, can’t turn off) • Basic Scheduling & Calendar • Job Tracking & Completion • Customer Management • Simple Invoicing & Payments Toggleable Modules (each with a switch + short description + “Learn more” link) • GPS & Route Intelligence Switch: On/Off Includes real-time tracking, day-progress monitoring, delay prompt we sketched, route optimizatio...
Preciso de um aplicativo de entrega de gás que cubra todo o fluxo de compra, do cadastro ao recebimento do botijão na porta do cliente. O escopo inclui: • Cadastro e login de usuários – autenticação simples e segura. • Sistema de pedidos – seleção de produtos, carrinho e confirmação. • Pagamento integrado via Pix, com retorno de status automático. • Rastreamento em tempo real do pedido no mapa, exibindo posição do entregador. • Painel administrativo na web para gerenciar produtos, preços, estoque, pedidos e entregadores.

I’m ready to move from wireframes to a working MVP for a cross-platform social networking app focused on seamless photo and video sharing. The goal is to launch simultaneously on iOS and Android, so the tech stack should either be truly native (Swift + Kotlin) or a proven cross-platform approach such as Flutter or React Native—whichever lets us iterate quickly without compromising performance on media-heavy feeds. Core scope • Implement secure user sign-up / sign-in and basic profile handling (name, avatar, bio). • Build a scrollable feed where users can upload, view and interact with photos and short videos. • Handle media compression, background uploads and efficient caching so the app feels fast even on slower connections. • Integrate push notifica...
I have a full set of annotated screenshots that outline every screen of a gas-refill ordering and delivery app. I now need those designs turned into a working mobile application that runs smoothly on both iOS and Android devices. The essentials are straightforward: customers must be able to place a refill order, track its status in real-time, and manage their personal profile (address book, past orders, basic settings). Payment integration is not required at this stage, so you can focus on a clean ordering flow and reliable tracking logic. I’m open to either native development or a cross-platform framework such as Flutter or React Native—as long as the finished build passes store review on both platforms and mirrors the UI in my screenshots pixel-for-pixel. Business Pur...
I need a developer who can take my concept for a music-therapy application and turn it into a polished product that runs smoothly on both iOS and Android.
