I want to turn a standard RC chassis into a smart, self-aware toy that can do far more than just follow joystick commands. The end goal is a prototype car that: • Detects obstacles in real time • Plans an optimal path around them • Switches between full autonomous driving and classic “manual” mode on demand Everything should be directed from a single mobile app that works seamlessly on both iOS and Android. From that app I need to: 1. Watch a live video feed (low-latency) 2. Toggle between autonomous and manual modes 3. See a simple map of the car’s planned path and any detected hazards 4. Push OTA firmware updates when new AI models are trained Hardware is already on hand (Raspberry Pi 4, camera module, ultrasonic sensors, ESC, and an ESP...
I want a complete, production-ready mobile application that runs smoothly on both iOS and Android. The core idea is a multi-resort booking platform wrapped inside a binary MLM structure: every user can reserve rooms across several partner resorts while simultaneously building a two-leg network that earns commissions from each down-line booking. Key elements to build • Resort booking engine – real-time room availability, multi-resort catalog, date/guest selectors, pricing rules and in-app payments. • Multiple bookings per user – one account may hold overlapping or future reservations, each editable or cancellable under policy constraints. • Binary MLM logic – automatic left/right placement, level-based commission calculations, secure wallet, payout re...

I’m launching a location-based augmented-reality game and need a developer who can deliver functional builds for both iOS and Android within the next month. Players will move through the real world to discover digital items and challenges, so precise geolocation and smooth AR rendering are critical. My ideal workflow is Unity (or another cross-platform engine you’re comfortable with) paired with ARKit, ARCore, and a mapping solution such as Mapbox or Google Maps SDK. I’ll supply the game concept, core mechanics, and all 3D assets; you handle coding, integrating the location services, and packaging the apps for TestFlight and Google Play internal testing.

Busco una solución que me permita disponer de varias direcciones IP geolocalizadas en ciudades específicas de México y alternar entre ellas de forma sencilla. Las ubicaciones que necesito cubrir son: Ciudad de México, Guadalajara, Monterrey, Mexicali, Tijuana y Ensenada. El objetivo principal es acceder a contenido local, por lo que la detección de la ciudad debe ser fiable en servicios de streaming, portales de noticias, apps deportivas y plataformas similares.

I want an app that scans the phone’s camera roll, recognises the same person across different shots, and then lets me decide exactly which images to forward. The core flow is simple: • First, the app analyses every photo, clusters faces that it believes belong to the same individual and shows me those groupings. • From there, I can pick pictures one-by-one or bulk-select them in three distinct ways: individually, by date range, or by geolocation. This mirrors the way I already think about my library, so the interface needs to surface those three filters prominently and let me combine them if I wish. • Once I have a final selection, the app should open the standard share sheet so I can send the chosen files through any installed channel (Messages, WhatsApp, AirDrop...
Procuro comprar, à vista, o código-fonte completo de um aplicativo IPTV em Kotlin semelhante ao IBO Player (versão 3.4 ou superior) acompanhado de um painel administrativo em PHP. Meu foco principal é o painel: ele precisa permitir o cadastro e gerenciamento de MACs e o controle de assinaturas mensais. Já possuo um painel funcional e o APK final, porém não tenho acesso ao código Kotlin; estou até desenvolvendo um projeto próprio, mas acelerar o processo comprando uma base pronta seria muito mais interessante. O que preciso receber: • Código-fonte do app em Kotlin, pronto para compilar no Android Studio. • Painel PHP com gerenciamento de MACs e assinaturas plenamente operante. • Instru&cc...
I need a compact multiplayer combat demo built in Unity that lets two five-player teams face off on a single symmetrical map. Think World of Warcraft’s third-person feel, but stripped down to the essentials—no progression, inventory, or persistent accounts. Core play loop • Players pick one of two visually distinct factions; mechanics stay identical. • Each faction offers a Tank (melee + defensive skill) and a Ranged DPS (projectile attack + burst skill). • Health management, ability cooldowns, and a central capture point with a progress bar decide the winner. A match ends when the timer runs out or a team fully claims the objective. Tech & scope • Pure Unity project—host-client architecture is fine. • Online networking can rely on...

Necesito una web view para mi sitio web para iPhone y Android. La app debe abrir exactamente la versión web, manteniendo su aspecto y todas sus funciones, pero con un extra clave: enviar una notificación push cada vez que un usuario reciba un mensaje de texto dentro de la plataforma. Necesito: • Compilaciones nativas para iOS y Android listas para publicar en App Store y Google Play. • Integración de notificaciones push que funcione cuando la app está en primer o segundo plano y, de ser posible, también en segundo plano restringido. • Icono badge/contador actualizado al llegar nuevos mensajes. • Código fuente bien comentado y un breve manual de instalación o recompilación. Valoro una solución que ut...
I need to move funds directly from my local bank account to a recipient’s bank in Cambodia. The goal is a one-off, hassle-free transfer—no payment gateways or third-party wallets—strictly bank-to-bank. Here is where I need your help: • Collecting and formatting the recipient’s Cambodian bank details so they meet SWIFT/IBAN requirements. • Walking me through compliance checks and any paperwork my sending bank might request (KYC, purpose of remittance, etc.). • Preparing the transfer order inside my online banking portal and confirming the routing codes, fee structure, and expected delivery time. • Verifying that the funds land in the Cambodian account and providing a simple receipt or confirmation screenshot once it clears. Acceptance wi...
I want to launch a mobile experience that blends live-stream shopping with seamless, in-app purchasing—think TTS. The build must ship for both iOS and Android from day one, with user accounts that can authenticate either through email/password or the major social platforms. Core functions I need working flawlessly: • Real-time live streaming where hosts can pin products on screen • A browsable product catalog that stays synced with my backend • One-tap, secure checkout inside the stream and in the catalog view Because I do not have a fixed preference on framework, you’re free to recommend React Native, Flutter, or any stack that delivers smooth video, stable commerce flows, and maintainable code. When you reply, please include: • Direct links or s...
Busco a un profesional que pueda crear una solución completa para la venta de materiales de construcción. El proyecto se divide en dos frentes claramente conectados: 1.

The project is a full-scale, cross-platform cricket fantasy gaming application that must run smoothly on both iOS and Android devices. I already have the feature set clearly mapped out, so the focus is on clean execution and rapid delivery within the next month. Core functionality to implement: • Live score updates pulled from a reliable cricket data API in real time • Robust fantasy team management where users draft, trade and track player performance • Dynamic leaderboards and rankings that recalculate instantly after every scoring event A modern, intuitive UI/UX is essential so users can glide from team selection to live match tracking without friction. The back end should be cloud-ready, scalable and secure, handling user authentication, scoring logic, push not...
I want a simple, reliable way for families to see exactly where their school bus is and how long it will take to reach their stop. The core flow is straightforward: • Students or parents open the app on iOS or Android, choose their school, bus number and stop from three drop-downs, and immediately see the bus’s live position on a Google Maps view along with an ETA to their selected stop. • The driver runs a companion screen on the same app; when they tap “Start Trip” the phone begins broadcasting its GPS location. Once the route is finished, they tap “End Trip” and tracking stops. • Only two roles are needed for the first release—Students/Parents (view-only) and Drivers (share location). A future administrator role could be added late...
I already have the complete Android source code and APK; now I need an identical iOS build targeted for iPhone only. Every screen, flow and feature must behave exactly as on Android—no additions, removals or alterations. Your job covers: • Setting up the new Xcode project and coding the app in Swift or Objective-C (your call, as long as performance and Apple guidelines are met). • Re-implementing any REST calls, local storage, push notifications and third-party SDKs present in the Android version. • Thorough testing on real iPhone hardware to make sure the build is stable and visually consistent. • Guiding me through App Store Connect, TestFlight distribution, metadata, screenshots and final submission until Apple approves the app. To move forward, please send m...

Hi, I have a complete, ready-to-implement SwiftUI iOS app (simple private journal/diary style app with local on-device data storage and basic processing features – no backend, no external APIs). The full code is already written and functional as an MVP. It's a small project with ~8 Swift files using SwiftUI and SwiftData.

Add basic app icon (I can provide or you create simple one). 4. Test on simulator and device. 5. Take App Store scr...
I’m expanding our mobile team and want an experienced developer who is equally comfortable in Flutter (Dart) and React Native (JavaScript/TypeScript). Our live products run on both iOS and Android, so every feature you tackle must compile cleanly and perform smoothly on each platform from the first build. THIS JOB IS IN THE US TIME ZONE ONLY + NEED WEEKEND AVAILABILITY The initial assignment is urgent—bug squashes and a small new module need to ship ASAP—yet the larger goal is an ongoing collaboration.

I want to launch a single mobile app that lets drivers handle every routine task around their vehicle without ever leaving their phone. The build has to be truly cross-platform—one code-base deployed to both iOS and Android—so users on either store get the exact same experience. Core modules I need right now are: • Check car details pulled live from the Vahan API • Pay traffic challans seamlessly inside the app • Recharge FASTag in just a few taps • Full buy-and-sell marketplace for used cars For the Vahan integration you’ll work with the official APIs to fetch RC details securely. Challan and FASTag flows will require payment-gateway integration (UPI & cards) and receipts stored in the user’s history. The marketplace should let any...

I need a production-ready chatbot I can license or resell to different clients. Its core role is real-time customer support, but it also has to handle FAQs, simple bookings, and any other routine queries that typically swamp a help desk. Integration scope The same bot must plug seamlessly into websites, native mobile apps (iOS and Android), and major social media channels (Facebook/Instagram, WhatsApp, etc.). I’m open to middleware such as Dialogflow CX, Microsoft Bot Framework, or a custom Node/Python stack—whichever you can prove will scale cleanly across all three environments. Key capabilities • Multilingual support: automatic language detection and translation so end-users get replies in their own language without manual routing. • Analytics & reporti...

Contact me if you have knowledge about PHP Laravel Back-End and Flutter Front-End My food-ordering app is already live on both the Apple App Store and Google Play. I will provide the complete Flutter front-end and Laravel back-end source, along with current store credentials. What I need now is a hands-on developer who can streamline the online payment flow—specifically, cut down the transaction time from the moment a customer taps “Pay” until confirmation appears—then produce fresh production builds and submit them to both stores. Scope of work • Review the existing Flutter checkout screens, Dart services, and the Laravel payment API. • Pinpoint and refactor any latency bottlenecks (network calls, serialization, DB look-ups, third-party SDK latency, ...

Users begin via a dedicated single-page website that redirects them to download the Android/iOS app, where they log in securely using OTP-based mobile authentication with auto-read access. They complete a structured biodata form covering personal, educational, professional, family, and contact details, after which the system automatically generates a digital profile with a unique Biodata ID; uploaded photos (2–4) are auto-watermarked with the community name and ID for secure identification. Profile activation occurs only after payment through UPI, card, or netbanking, and paid profiles are instantly routed to admin review, where admins can approve (auto-assigning users into groups via sequencing logic) or reject with automated Razorpay refunds and notifications, while retaining the a...

I have a fully-functional mobile app available on both the App Store and Google Play. It is stable, but it needs a face-lift and a handful of new capabilities to keep users engaged. What I need right now • A complete redesign of the user interface. I already have clear ideas, sketches, and references; you will translate them into polished mock-ups and then implement them natively on iOS and Android. • Development of several additional features that build on the current codebase. These are specific to my product and I will share detailed requirements once we start, but they go beyond simple social-media hooks or push messaging. Typical workflow I envision 1. You transform my UI ideas into design comps (Figma, Sketch, or similar). 2. We iterate quickly until the look and ...

I have the concept and branding for a new delivery service and now need a complete app built in Flutter that runs smoothly on iOS, Android, and the Web from a single codebase. Core features I’m counting on you to implement include real-time order tracking on a map, secure payment integration (cards and popular wallets), and reliable push notifications for every status update. At this stage I do not require any form of user authentication, so you’re free to focus entirely on the purchase-to-doorstep flow without login screens or social sign-ins. My priority is clean, well-structured Dart code, tested on the latest stable Flutter channel, and easily maintainable going forward. If you’re familiar with Firebase, Stripe, or similar back-end services, please mention it, as ...
I’m building a mobile e-commerce application and need an experienced Flutter developer to take it from UI mock-ups to a fully functional release on both iOS and Android. The app must feel lightning-fast and intuitive, with these core capabilities baked in from day one: • Product search and filter that handles large catalogues without lag • A reliable shopping cart flow that remembers the user’s picks across sessions • Secure payment-gateway integration for card, wallet, and any future methods I add I will supply brand assets, product data, and the necessary API endpoints; you wire everything together in clean, null-safe Dart code, follow Flutter’s best practices, and keep the architecture easy to maintain. Deliverables • Complete Flutter sourc...
The project centres on creating a polished mobile application tailored for the hospitality sector—from hotels to boutique guest houses and restaurants. Core objectives are to simplify guest interactions, drive direct bookings and cultivate brand loyalty through a seamless digital experience. Scope of work I want a full-cycle build: concept refinement, UX/UI design, coding, testing and launch support. The exact feature set will be finalised together, but it should comfortably cover everyday guest touch-points such as reservations, real-time availability, personalised offers, push notifications and an easy feedback flow. A lightweight web-based admin panel will also be needed so staff can update inventory, review analytics and respond to guest comments without technical hassle. ...
I want to bring my concept “Sz bersedih” to life with a clean, user-friendly mobile application and a coordinated stream of social media posts that will launch alongside it. Here’s what I need from you: • A fully-functional mobile app, built with modern frameworks that allow smooth performance and an intuitive interface. • A starter package of social media content (captions, visuals or short-form video ideas) that matches the app’s tone and encourages early adoption. The app should be ready for store submission, and the content should be formatted so I can publish immediately on my preferred channels. If you have questions about features or branding, let’s discuss them early so the final hand-off is seamless.
I need an experienced mobile-app QA specialist to run a full, end-to-end test cycle on our live application for both Android and iOS. Functional accuracy is my top priority, yet I still expect you to keep a close eye on UI/UX polish and overall performance. You will work with a very wide device matrix: more than 100 Android handsets across Vivo, Oppo, Samsung and other brands—covering low, mid, and flagship tiers plus the usual range of screen sizes. On iOS, please cover every build from iPhone 11 onward, including the latest release. Critical flows such as login & registration, payment processing, and in-app navigation must be exercised thoroughly along with the rest of the feature set, so treat the assignment as a full regression sweep rather than a spot check. Deliverables ...
Our employee-attendance app on React Native needs a focused round of stabilization. Right now I’m seeing two pain points: location readings are often off the mark and, even worse, background updates stop coming through at unpredictable intervals. Both iOS and Android builds behave the same way, and we’re using a fully custom location module rather than Google Location Services or Mapbox, so you’ll be digging directly into our own codebase. What I need from you: • Diagnose why the coordinates drift and why background updates stall. • Refactor or rewrite the custom tracking module for reliable, high-accuracy fixes on both platforms. • Verify the solution on real devices (not just simulators) and document any OS-level settings or permissions we must keep ...
I’m kicking off a multi-platform compliance audit solution and want to get the first, fully functional Android build in place before we move on to iOS and a web front end. The core workflow is straightforward: field teams open the app, enter audit data into structured forms, snap photos on-site, and sync everything securely to the server. An intuitive UI, offline capability with background sync, and airtight data protection are essential because the information collected is often sensitive. Here’s how I see the first milestone coming together: • A production-ready Android app with clean, modern Material design • Dynamic forms that let users add, edit, and validate audit data on the spot • Integrated camera access so photos attach seamlessly to each record...
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...

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 cod...
I need an end-to-end build of a mobile food ordering and delivery platform that mirrors the smooth user journey of services such as Zomato and Swiggy. The core experience must let customers browse nearby restaurants, place an order in a few taps, pay securely, and watch their courier move in real time on a map.
