Estoy atascado con la validación de las transacciones de las compras in-app de mi aplicación iOS. Los productos ya aparecen en App Store Connect y la interfaz de usuario de compra se muestra sin problema, pero al procesar la operación me devuelve errores de validación y la transacción no queda registrada correctamente. Necesito que revises conmigo la configuración actual en App Store Connect y el código que uso con StoreKit / Swift. El objetivo es: • Detectar y corregir la causa de los errores de validación. • Ajustar la lógica para registrar y finalizar las transacciones de forma segura. • Probar las compras (incluida la restauración) en el entorno sandbox hasta que queden completamente funcionales....

Necesito una aplicación OTT/IPTV totalmente personalizada para Smart TV LG (webOS) y Samsung (Tizen). Lo esencial es que reproduzca contenido en vivo y ofrezca una sección de series VOD, con un manejo fluido mediante el control remoto y una interfaz que siga las guías de UX de ambas plataformas. Además: • Quiero dejar abierta la posibilidad de añadir modelos de suscripción o pago dentro de la app; prefiero discutir las opciones contigo para elegir la mejor ruta técnica y comercial. • Por ahora no requiero integraciones externas (redes sociales, sistemas de pago ni analítica); la prioridad es un reproductor sólido y estable. • Aprecio propuestas que incluyan empaquetado listo para tienda (archivos .ipk y .wgt...

I want a lightweight iOS-only application that guides users through a 30-day “break the habit” challenge. A user can enter up to four habits at the start; from there, each calendar day presents a single confirmation screen. When the user logs success for all chosen habits that day, an illustrated tree grows—advancing to a new stage every seven consecutive successful days and unlocking a small achievement badge. Core flow • Welcome screen → add (or edit) up to four habits • Daily check-in screen with a single, clear “Done for today” interaction • Animated tree that visually grows at days 7, 14, 21, 30 • Simple history view summarising which days were completed or missed The interface should stay clean, friendly and motivat...

I’m kicking off a brand-new social networking mobile app and want to start with one rock-solid cornerstone: user profiles. Your task is to design and code this core module so we have a clean, extensible foundation for all future features. Here’s what I need from you: • A fully functional profile screen where users can view and edit their photo, bio, and basic details. • Secure account creation and authentication (email, Google, or Apple—whichever you’re most comfortable implementing first). • Simple back-end or cloud setup to store and fetch profile data reliably. • Clear documentation and commented code so any developer joining later can pick up where you leave off. • A short walk-through video or call at hand-off showing how eve...

I have a live SwiftUI-based social app that already ships chat, video feeds, stories, live scenes, an in-app currency (stars) and subscription flow. The code follows MVVM, talks to a set of REST back-ends and is in the store today. What I need now is an experienced iOS engineer who can drop into the existing project, diagnose issues quickly and raise the overall quality bar. The immediate focus is three-fold: • First, do a thorough walkthrough of the current codebase so you understand our MVVM layers, networking helpers and IAP logic. • Next, remove bugs that are spiking our crash reports and tighten up general stability. • Finally, tune performance in the chat and media areas, then layer in a handful of small feature requests we already have queued for those modules....

I want to swap the live camera feed on an older, jail-broken device (iOS 13–14 running Dopamine or a similar rootless setup) with a predefined asset so I can study how iOS handles media input. The tweak should let me point the system camera APIs to either: • a single static image (JPEG or PNG) • a looping video file (MP4) Ideally I can drop the asset into a folder or set its path in a simple prefs bundle, then toggle between “live”, “image”, and “video” without rebooting. No need for App Store integration, entitlement trickery, or third-party service hooks—this stays strictly on-device for personal, non-commercial testing. Deliverable • Rootless .deb that installs cleanly on Dopamine • Preference pane (or command-li...

I’m ready to move from concept to code on a brand-new productivity app and need a developer who can deliver a polished experience on both iOS and Android from day one. At its core, the app must let users create and track tasks, view and sync those tasks with their calendar, and collaborate seamlessly with teammates in real time. The flow should feel effortless: • quick task capture with priorities and due dates, • automatic calendar updates so schedules stay in sync, • shared workspaces where team members can comment, attach files, and see progress instantly. A clean, distraction-free interface is vital; think intuitive gestures, subtle animations, and fast load times even on older devices. Whether you prefer Swift + Kotlin, Flutter, or React Native, I’m o...

I need a compact yet capable duo—one creative UI/UX designer and one iOS developer—to bring a friendly pregnancy-companion app to life. The concept is straightforward: each week the baby’s growth is visualised with a fruit-size comparison and accompanied by an encouraging message to the mother. Your scope covers everything from fleshing out a clean, mother-centric interface in Figma or Sketch through to native Swift development, internal TestFlight testing and final submission to the Apple App Store. I want this handled end-to-end so I’m not juggling multiple freelancers. Deliverables • High-fidelity UI/UX files and clickable prototype • Swift-based iOS app that mirrors the approved designs • App Store–ready build with screenshots, descr...

I’m looking for a Swift-savvy iOS developer who can turn my finished Google AI Studio design (supplied as TSX files) into a production-ready SwiftUI application that downloads video and audio from popular social networks. Here is the full scope of work: • SwiftUI build: translate every screen from the existing TSX design into clean, maintainable SwiftUI code, keeping the original look and feel intact and making sure the layout is 100 % iPhone-compatible, all the way back to the oldest iOS version still accepted by the App Store. • Background downloading: implement reliable, resumable downloads so users can leave the app while large files finish in the background. • No login flow: the app must work without any form of user authentication. • Local storage ...

Our production Android app is stable in the market, but I now need a rapid, one-month push to get the entire platform ready for a broader launch .The existing codebase will be shared the moment we agree on the scope, after which I need you to work end-to-end across web services and mobile. Here is what has to happen during the sprint: • Backend upgrades – Refactor database management for speed and reliability – Tighten user authentication flows and token handling – Clean up and extend API interactions so both mobile clients consume a single, consistent layer – Add real-time notifications (push and in-app), advanced analytics collection, and payment processing • Front-end polish on the current Android build – Refresh the user in...

I need a fully-featured mobile app published on both Google Play and the App Store so my patients can reach me easily and securely. The core experience is a private messaging channel between each patient and myself, backed by phone-number authentication with a one-time password flow (no email or social log-ins). Inside the chat screen patients should be able message and also start voice with a single tap. All conversations, calls, and bot interactions must remain HIPAA-compliant and encrypted in transit and at rest. I am open to the tech stack—React Native, Flutter, or native Swift/Kotlin are all fine—as long as the final build passes App Store and Play Store review guidelines. You will also set up the lightweight backend necessary for OTP verification, real-time messaging, ...

I need a seasoned system-level engineer to build a truly standalone mobile operating system—not just an Android or iOS fork. The goal is to deliver a fully bootable image that ships with: • A visually distinctive, lightweight user interface designed from the ground up for touch • Security enhancements at kernel, system service, and application layers (hardened permissions, secure boot, encrypted storage, etc.) • A native app-store framework so third-party developers can publish, sign, and update apps over-the-air You’ll own everything from low-level board support through to UX polish, so experience with toolchains such as GCC/Clang, device tree configuration, kernel customization, and UI frameworks (Wayland, Qt, or similar) is essential. If you have previ...

I already have a Rork-built mobile app for our radio station. The MP3 stream plays perfectly in the existing player, but the moment I try to send the audio to an external speaker via AirPlay on an iPhone, nothing happens. Here’s exactly what I need: • A clean implementation of AirPlay that works on iOS 14 and newer. • Coverage for every audio event in the app, not just the built-in player, so listeners can seamlessly switch to AirPlay any time music is playing. • No change to the current MP3 streaming flow—just add the AirPlay layer. I’ll hand over the current Xcode project (built with Rork) and point you to the streaming endpoint. Deliverable is a working build plus the modified source, along with brief notes on the changes you made so I can ke...

I run a 24/7 entertainment Spanish channel and I want viewers to be able to watch it directly from a dedicated Samsung Smart TV app built for the current Tizen platform. The stream is already up and running; what I need is a polished, store-ready application that can: • open and play my live HLS/RTMP feed instantly • display a simple, branded interface that looks great at 4 K • respond smoothly to the Samsung remote (directional pad, play/pause, back) • pass Samsung’s certification requirements so it can be published in the Smart Hub I will supply the logo, color palette, and streaming URL. You handle the full Tizen build—coding, UI styling, testing on real sets or the Samsung Emulator, and packaging the submission bundle. Once I can install the .wgt...

I want my iPhone hardened so it stops listening to—or broadcasting—every kind of beacon signal and ignores any future provisioning attempts. The focus is on three specific vectors: Wi-Fi beacons, Bluetooth beacons and location-based beacons. Here’s what I need from you: • A step-by-step configuration (or profile) that disables discovery, advertising and scanning for the three beacon types, while still letting me keep everyday services such as calls, basic data and SMS working. • Clear instructions on blocking carrier or remote-management provisioning without jail-breaking the device, or an alternative secure method if a profile alone cannot achieve this. • A short call or screen-share session so I can replicate the changes on any future iOS update...

My TypeScript-based app needs a fresh set of eyes. Two problem zones keep slowing development: the user interface occasionally renders the wrong state, and the data-processing layer throws intermittent logic errors. I’d like you to trace the root causes, patch them, then reorganise the affected modules so the codebase is cleaner and easier to extend. Because the troublesome behaviour reveals details of planned features, I’ll share concrete scenarios and test cases once we have a signed NDA. After that you will have full repo access, current build scripts, and unit test coverage reports. Deliverables • Fixed UI and data-processing bugs, confirmed by our existing automated tests • Refactored, well-commented TypeScript modules that follow our linting rules • A...

I have an idea for a “shnarps” style app that lets groups of friends create small, private tournaments where everyone puts real money into the pot and competes for the top spot. The entire experience will live on iOS only, and I picture a clean, modern-minimal interface that feels as intuitive as Apple Wallet: light backgrounds, clear typography, zero clutter. Here’s the core flow I’m after: a user downloads the paid app, signs up, invites friends to a tournament, each player stakes an agreed amount through an in-app wallet, play proceeds, and the winner (or top three, depending on settings we define) receives automated payout. Because we’re handling peer-funded prize pools, I need advice on the legal framework—what licences or jurisdictional restrictio...

I’m building a fully-featured voice assistant that users can download on both iOS and Android. Think of it as a pocket-sized helper that can listen, understand, and act on spoken commands—setting reminders, fetching quick answers, controlling smart-home services via API, or triggering in-app actions. Here’s what I need from you: • A native or cross-platform mobile app (Swift/SwiftUI + Kotlin, or Flutter / React Native—whichever lets us land on both stores quickly and cleanly). • On-device and cloud speech recognition so the assistant responds within a second or two, even on slow connections. • Natural-language understanding: basic intent detection, entity extraction, and a fallback to a large-language-model endpoint when the user asks something ...

I’m ready to turn a fresh social-networking idea into a polished iOS app focused squarely on entertainment. The first release needs just one mission-critical feature: a real-time messaging system that feels as fluid as Apple’s own Messages. Everything else—profiles, content sharing, and any flashy extras—can wait for later iterations, so your attention can stay on building a rock-solid chat experience. Here’s what I have in mind: • Swift or SwiftUI codebase that compiles cleanly in the latest Xcode • Secure user authentication (Apple ID preferred, but I’m open to Firebase/Auth0 if you have a strong argument) • 1-to-1 and group messaging with push notifications that actually land • A lightweight, modern interface that looks at ...

I’m ready to bring a full-featured, Uber-style taxi service to life and need a developer (or small team) who can take the project from concept to launch on both iOS and Android. The passenger app must include frictionless user registration and secure login, real-time ride booking with live vehicle tracking on a map, plus in-app payment integration that supports major cards and digital wallets. In parallel, I also require a separate driver app. It should mirror the passenger experience where appropriate, receiving ride requests, turn-by-turn navigation, earnings summaries, and status toggles, while keeping the codebase as maintainable as possible. Key expectations • Native or cross-platform code that meets Apple App Store and Google Play guidelines • Clean, well-docume...

I need a single AI application that can see, hear and speak to the user. Using my own OpenAI key (or, if you prefer, a Gemini or Claude endpoint), I want you to wire conversational logic with the device camera so the assistant can recognise whatever the lens captures—faces, emotions, objects, actions, text, you name it—then hold a natural dialogue about what it sees. The build has to run everywhere: a mobile version for iOS & Android, a web app that works in the browser, and a desktop release for Windows and macOS. Users should be able to create an account, log in, and start interacting immediately. Speech-to-text converts their voice to prompts, vision models process the live feed, and text-to-speech delivers the reply in real time. For LLM calls, default to ChatGPT via ...
