Nga 237,796 vlerësimet, klientët vlerësojnë iPhone Developers 4.9 nga 5 yje.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...

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’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 an e-commerce concept ready for development and now need a complete UI/UX package that feels modern, intuitive, and conversion-focused on mobile. The core flows to cover are product search with smart filtering, a smooth shopping-cart and checkout sequence, plus user account areas for order tracking and profile management. The work starts with clarifying user personas and journeys, then moves into low-fidelity wireframes, high-fidelity visual designs, and finally an interactive prototype I can hand straight to developers. Figma is my preferred tool, but Sketch or Adobe XD are fine if you can export assets cleanly. Deliverables • User-flow map covering search, browse, product detail, cart, checkout, login/signup, and account dashboard • Full set of wireframes for e...

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 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. What I want Sintra AI to do: • Manage posting across my social platforms (scheduled posting, content queue, captions, hashtags) • Help create/organize content themes (recruiting POV, training reps, athlete visibility, behind-the-scenes, updates) • Monitor and respond to DMs and comments (basic replies, FAQs, and routing serious inquiries to email/website) • Set up a simple communications workflow: • If someone asks “price / how it works / can we try it” → respond with a clear message + send them to my website/contact • If it’s a schoo...
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. Here’s what I need from you: - Guide me through registering a fresh, company-owned Apple ID (since none exists yet). - Enroll that Apple ID in the Apple Developer Program under the Organization option, ensuring the D-U-N-S data is matched and the account becomes active. - Walk me through initial App Store Connect setup so we’re ready to upload builds for iPhone, iPad, and Mac the moment development is finished. Acceptance Criteria: The new Apple ID is created, verified, and fully enrolled in the ...
I’m building a new marketplace focused exclusively on physical goods and need an end-to-end development partner who can deliver both a responsive web app and companion mobile apps for iOS and Android. The platform must feel seamless no matter how users access it, so shared business logic and a single back-end are important.

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 (...

I’m getting ready to introduce a brand-new software application to the market and need a launch campaign that takes me from pre-release buzz all the way through public rollout. The core objective is simple: turn this digital product into a successful, attention-grabbing release that drives early adoption and sets the stage for long-term growth. Here’s what I’m looking for: • A clear go-to-market roadmap that maps out messaging, channels, and a realistic timeline from soft-launch to full release. • Compelling creative assets—landing page copy, email sequences, and social snippets—that speak to our target users and highlight the app’s key benefits. • Practical guidance on app-store presence and beta-tester engagement so we gather soci...
I’m building the first “AllTrails-style” guide dedicated to obstacle-course racing (OCR) training spots and need a production-ready mobile application that runs smoothly on Both iOS and Android. The core experience hinges on a live map (Google Maps API or comparable) where users can drop pins, attach geo-tagged photos, write descriptions such as “Great for rope climbs—public park with pull-up bars,” rate the spot, and tag it with OCR-specific attributes like grip strength, endurance, or mud terrain. Beyond discovery, the app must feel social. Logged-in athletes should be able to comment, favourite, post challenges (“Beat my time at this spot”), and build simple public profiles. Powerful filters—difficulty, obstacle type, proximity, use...
I need a full-stack developer who can build an AI-driven application that lets me do two things in one place: first, generate complete music videos, and second, train and manage my own AI models. For the music-video side, the user should be able to pick a visual style and drop in a custom voice track that the system blends seamlessly with the chosen look. Adding extra video effects is something I may explore later, so please keep the architecture flexible enough to plug that in without a rewrite. On the modelling side, I want a workflow that lets me start a new model from scratch, feed in data, train, save, and then reuse that model inside the video generator. Ideally this is handled behind a clean dashboard rather than command-line steps. Core expectations • Intuitive UI/U...
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 ...
I’m building a mobile application that lets field executives—loaders, helpers, delivery riders and other gig workers—locate nearby jobs simply by entering their pincode. The same app will handle a ₹100 monthly subscription, display each company’s salary plus incentive structure, and refresh a personal dashboard so users see their earning potential day-to-day. I need the complete solution for both Android and iOS. Core modules include: • Pincode-based job search that pulls openings from our partner companies in real time • In-app subscription flow (₹100/month) with secure payments and automatic renewal handling • Salary & incentive dashboard that visualises confirmed shifts, projected payouts and daily totals AI will sit at the centre of the ...
I need a polished e-commerce application that works seamlessly on both iOS and Android. The storefront should showcase my full product catalog, allow quick, intuitive search, and let customers create accounts or sign in with the usual social or email options. Once users are ready to purchase, the checkout flow must connect to a secure, widely used payment gateway so transactions clear without friction. I value a clean UI, fast load times, and code that scales—preferably built with a single code-base framework such as Flutter or React Native, though I’m open to native development if you can explain the long-term advantages. Deliverables • Fully functional iOS and Android builds • Admin-side access to add, edit, or remove products and view orders • Integr...
Project: Next-Generation Mobile Racing Game (Ultra-Modern, 2026+) I am looking for an experienced mobile game developer or game studio to build a next-generation car racing game inspired by fast-paced arcade racers like Asphalt, but significantly more modern, more refined, and more visually impressive.

I need both the Android and iOS builds of my app brought up to the latest 6am Mart release so that all existing features continue working after the core upgrade. There is no redesign involved—the task is strictly functional. Primary areas to tackle • User authentication – the current login and token flow occasionally fails after the recent server-side updates. I need seamless sign-in on first try, consistent session persistence, and full parity between the two platforms. • Payment systems – Stripe and Razorpay SDKs must be bumped to their current stable versions and retested so every purchase, refund, and webhook callback runs without error on Android 13+ and iOS 17. • 6am Mart core update – integrate the official latest release, resolve any br...

I have built an app using lovable and want it now turned into an app on ios and android. It doesn't need to go in the app store, it can be published via test flight for iOS packaged as an apk for android as it only needs to be used by about 100 users. Ideally we will be able to update code in github and the apps will update on the devices, but i understand if this is not possible.

I’m adding a dedicated Bill of Lading module to my React Native application and I want every shipment’s status to be visible the moment it changes. The core of the job is wiring the app to the provider’s API so that users on both iOS and Android can: • see real-time status updates the second they are posted • receive in-app and push notifications for each status change • review a full historical timeline for every Bill of Lading You’ll design the data flow, connect the REST/WebSocket endpoints, build the UI screens, and make sure the new code plays nicely with the existing Redux store and TypeScript setup. Proper error handling, offline caching, and unit tests are expected so I can ship to TestFlight and Google Play without surprises. **Relevan...

I am about to unveil a new iOS and Android app that connects users with a Personal Stylist, Personal Shopper, and Wardrobe Stylist in one place. Before we open the doors to the public, I need a set of polished, professional-looking visuals that will help me attract new users and convey the value of the platform with a clear, formal tone.

English: I am planning to build a mobile non-custodial platform for digital token transactions on iOS and Android, including a backend.

I need to confirm whether my wife's iPhone placed a voice call immediately before a video I shot in Hawaii just after midnight on September 7, 2025. The most likely destination is, but I want definitive proof—exact dialed number, start-to-end timestamps, and total duration. You may work with the raw data in whichever way is easiest: I can grant temporary, read-only access to my T-Mobile account, or pull the usage log myself and send you the file. Because I’m unsure of the precise moment the video begins, I’ll also need help extracting or confirming the video’s internal timestamp so we can align it with the carrier records. (A forensic review of the video itself was done by Md Nazmul H. in October 2025; that report is available if it helps.) Deliverables: &bu...
