Nga 232,901 vlerësimet, klientët vlerësojnë iPhone Developers 4.9 nga 5 yje.I need an automated chatbot that can handle customer support queries directly inside our existing mobile app. The bot should greet users, understand common questions about our services, and deliver accurate, friendly responses without human intervention. Where answers fall outside its knowledge base, it must smoothly escalate to our live support queue so no conversation is ever dropped. Key deliverables: • Dialog flow design covering all current FAQs, account issues, and order-status checks • Natural-language understanding setup (Dialogflow, IBM Watson, or similar) with intent and entity training • Seamless SDK integration for both iOS and Android versions of the app • Simple admin panel or JSON file for my team to update responses without code changes • H...
I need a mobile application that spotlights the nightlife scene across ten different urban cities. The app’s single, crucial focus is a polished venue-profile section: each profile must display a concise venue description alongside accurate opening hours. Everything else—from navigation flow to visual style—should revolve around making these profiles quick to discover and pleasant to read. You are free to recommend the tech stack and architecture, but I do expect clean, well-documented code, straightforward deployment instructions, and a user-ready build for both major mobile platforms once development is complete. If this first release hits the mark, I will consider adding extra modules later (for instance, event listings or user reviews), so structuring the projec...
I’m extending our engineering team on a long-term software development project that targets both iOS and Android. The job is hands-on coding: committing well-structured, tested features to our Git repo, reviewing pull requests, and gradually tackling more complex tickets as you grow with us. I’m specifically seeking a beginner to mid-level developer who (1) currently resides in the United States and (2) identifies as female. I want to invest time in mentoring someone reliable, curious, and ready to stick with the project for the long haul. The current stack is Swift and Kotlin with a RESTful back end. Familiarity with React Native, Flutter, or similar cross-platform tools is welcome but not mandatory—what matters most is clean code, steady communication, and a learning ...
I'm looking for an experienced mobile app developer to create a social networking app for Android. Key Requirements: - Design and develop an intuitive, user-friendly interface - Implement real-time messaging and notification features - Build secure user authentication and profile management - Integrate multimedia sharing capabilities (photos, videos) - Ensure app performance and scalability Ideal Skills and Experience: - Proven experience in Android app development - Strong knowledge of Java/Kotlin and Android SDK - Experience with real-time data and backend integration - Familiarity with UX/UI design principles - Ability to conduct thorough testing and debugging
I’m putting together a fast-paced, first-person shooter for smartphones and I’m looking for a developer (or small team) who can take the project from prototype to store-ready release on both iOS and Android. The core experience revolves around three fully-playable online modes—Deathmatch, Capture the Flag, and a lightweight Battle Royale—so solid, low-latency networking is essential. You’re free to work in Unity, Unreal Engine, or another proven mobile-friendly stack, as long as the end result hits 60 FPS on current mid-range devices and offers seamless cross-platform play. Voice chat, simple lobbies, and quick matchmaking are must-haves; cosmetics, progression, and monetisation hooks can be stubbed in for now as placeholders. Deliverables • A playa...
I’m ready to translate a fresh concept into a polished, production-ready Android application. The single most important piece of this build is a seamless, secure in-app purchase experience powered by Google Play Billing, allowing users to buy and restore premium features or content inside the app. No account system or push notifications are needed for the first release; the emphasis is on clean UI, solid Kotlin/Jetpack architecture, and bullet-proof purchase handling for consumables, non-consumables, and—if practical—subscriptions. I will share wireframes, artwork, and detailed user flows as soon as we kick off. If you have suggestions on payment flow optimisations, crash-free implementation patterns, or store listing compliance, feel free to bring them forward. Deliver...

I would like to build an application that has a very similar interface as whats app to allow customers to place orders based on real time stock available. Currently customers place orders via whats app and have made it clear they do not want to switch to a website but may be open to trying an app for orders if it is very simple. We want to move away from whats app as we manually log orders from whats app chats and due to the volume and difference in the orders, we tend to have human error while logging orders. The app is for fresh produce (vegetables, fruit, mushrooms, herbs etc). Currently we have 20sku's but want to add more (wont be more than 40 total sku's). The idea is to have as much simplicity as possible as the customers tend to be older persons who are not as tech savy...

I’m planning a fully fledged Battle-Royale game for both iOS and Android and need an experienced mobile developer or team to turn the concept into a polished, scalable app. The core loop is classic last-player-standing, but I want it to feel modern, visually striking and ready for live-ops from day one.

I’m planning to build a mobile productivity tool focused solely on task management and to release it simultaneously on iOS and Android. The first milestone is a clean, intuitive interface that lets users create, prioritise, and track tasks, with push-notification reminders and offline access that syncs when a connection returns. Calendar integration and broader collaboration tools can wait for later versions; right now I want a rock-solid core experience. End-to-end delivery is essential. That means UX research, wireframes, polished UI that follows each platform’s design language, the complete codebase (Swift/Kotlin or a high-quality framework such as Flutter or React Native), an API layer if you decide server sync is best, and fully tested release builds ready for the App Sto...
I’m building a modern, Spare-Room–style marketplace where landlords and tenants can connect effortlessly on iOS, Android, and the web. Before a single line of code ships, I need a polished, modern-and-trendy UI/UX that feels instantly familiar to everyday renters yet powerful enough for professional hosts. Core features to be designed and built: • User profiles for both landlords and tenants • Robust search and filtering for available properties, including city or specific-quarter targeting • In-app messaging so parties negotiate without leaving the platform • Transparent pricing display plus optional “Top Listing” adverts to boost visibility • Landlord verification workflow to maintain trust and safety • Comprehensive admi...
I’m building an online “rental boyfriend” platform and need both a full-featured website and companion mobile apps (iOS and Android). The core of the product is simple: visitors browse verified profiles, check availability, and place a booking—nothing more elaborate for now. Here is what I expect as the first release: • Website: responsive front end, secure login, profile pages with photos and bio, a calendar-style availability checker, and a straightforward booking flow that captures the chosen date, time, and basic contact details. • Mobile apps: native or cross-platform (React Native, Flutter, or similar) mirroring the same user-profile and booking experience found on the web. • Shared back end: one database and API powering both channels s...
I need a top-tier engineer to build a private mobile-API sniper able to claim 2- and 3-letter Instagram usernames faster than anyone else. The solution has to run against both Android and iOS endpoints and must never touch browser automation. Here is the performance bar I expect: the service should comfortably sustain more than 1,000 requests per second while keeping end-to-end latency below 50 ms. To achieve that you may architect a multi-threaded runner, spin up geographically distributed workers, or use any other creative optimisation—so long as the target numbers are met in real-world tests. Signature encryption, device fingerprinting, and the dreaded 429 rate limits all need to be bypassed with a custom-built approach rather than off-the-shelf libraries. Once a username is sec...
I’m commissioning a FlutterFlow application for simultaneous release on the Play Store and the App Store. The product centres on streaming and downloading audio content, backed by Firebase services, and needs to be ready within 4–5 weeks. Scope of work • Configure Firebase Auth and Firestore so user data and content lists stay in sync across platforms. • Build an in-app audio player with background playback, seek, and offline caching. • Embed a PDF viewer and video playback screen for supplementary material. • Create a secure, server-side access-code mechanism that unlocks premium sections after validation. • Prepare, test, and hand over production-ready Android (.aab) and iOS (.ipa) builds plus the full FlutterFlow project. Please send a fi...

I’m looking for a developer who can build a straightforward social-media style Android application. The idea is “bagus dan mudah”—clean, intuitive, and quick to ship. Core requirements • Native Android build (Kotlin or Java). • Basic social features: user sign-up/login, profile page, post creation with text + image, like/comment. • Cloud-based back end (Firebase is fine) for authentication, real-time database, and image storage. • Lightweight, modern UI that keeps navigation down to two or three main screens. • Deliverables: working APK, full source code, brief setup/read-me so I can run it locally or hand it to another team later. Nice-to-have (let me know if you can include) • Push notifications for new likes or comments...

I have already built and fully tested my m application using Google’s Studio AI tools and now I’m ready to push it live. My developer accounts are active and verified; what I need is an experienced hand to take the project across the finish line—compiling the release build, signing it properly, completing the store listing, and submitting it for review.

The entire codebase is stable and feature-complete; no new functionality or UI changes are required. I have an active Apple Developer account and will supply the necessary certificates, provisioning profiles, and Store listing assets as soon as we start.

Acceptance will be complete when: • The archive passes Xcode validation with no critical warnings. • A TestFlight build is available for internal...
I’m launching an online shoe store and need a seamless shopping experience that lives both on the web and inside native iOS / Android apps. The site and the apps should share one product database so inventory, pricing and order history stay perfectly in sync. Core requirements • Customer reviews must be built-in and easy to moderate. Each product page should display ratings, written feedback and reviewer photos. • Apple Pay and Google Pay have to be available at checkout from day one; the flow should feel native inside the mobile apps and equally friction-free in the browser.

I’m looking to have a brand-new Android mobile application developed. At this stage, my priority is to clarify and capture the app’s main objective in a way that guides the entire build. Once we have that objective defined, I’d like you to handle the full development cycle for a first operational version on Android devices. Key goals • Work with me to refine and document the core purpose of the app. • Translate that purpose into a lean set of features for an initial release. • Design, code, and test the Android application so it runs smoothly on current OS versions. What I’ll provide • My high-level idea and desired outcomes. • Timely feedback on wireframes, feature lists, and builds. What I need from you • Experience building ...
All screens, flows, and assets for my medical-health app are already laid out in Figma; what I need now is the full build—iOS, Android, and the backend that ties them together. The scope covers everything from setting up user authentication through to submitting the binaries to the App Store and Google Play. Along the way the app must hook into three key integrations I’ve planned: • Payment gateways for subscription and one-off charges • Health data APIs so users can sync with Apple HealthKit / Google Fit out of the box • A real-time messaging system that supports secure in-app chat and push notifications I’ll share the complete Figma file plus a short functional spec the moment we kick off. Pixel-perfect implementation is important, but so is soli...
I need a straightforward yet reliable solution that lets me run several clinics from a single platform. Core workflow starts with a patient entry form that captures demographics and immediately opens a running history for each record. The history must log their medical conditions, previous appointments and current or past medications without fail; every new visit simply appends to that timeline so nothing is lost. Bookings will be handled through a list-view appointment module—speed is more important than a visual calendar—so staff can scan, add or modify slots quickly. Because the group owns more than one location, the system should recognise which clinic a booking belongs to and allow easy reassignment if a patient switches branches. On the mobile side I want companion apps...
I need a seasoned iOS engineer to wire full Stripe support into my Swift-based app. Your task covers both sides of the fence: • In the app: build clean, production-ready flows for payment processing and payouts using Stripe’s latest iOS SDK. The UI is already in place; hooks for card entry, Apple Pay and instant payout status simply need reliable Stripe logic behind them. • On the server: stand up a small, well-structured Node.js backend (Express is fine) that handles customer creation, payment intents, webhook handling, and payout scheduling. The mobile client should talk to it through lightweight, documented endpoints and all secrets must remain server-side. I’m interested in developers who have shipped several Stripe-to-iOS integrations before and can point me t...
AI Powered image heavy app for the service industry. The app needs to be available on both iOS and Android platforms.

Its a unique app with no competitors on the market, and solves a very common problem in the industry
I’m moving an existing Unity project up to the latest LTS release and the console is now lighting up with compilation errors tied to an outdated SDK. The culprit is a “fragment” SDK that our user-interface elements rely on; anything that touches those UI fragments refuses to compile. Here’s what I need from you: get the project running in the newest Unity version, bring that fragment SDK (and any other hidden dependencies) up to date, and hand the game back completely error-free. Deliverables • Project opened in the current Unity LTS with zero compilation errors • Updated or replaced fragment SDK plus any secondary outdated packages • Clean builds: Android (AAB/APK) and iOS (IPA or Xcode workspace) Acceptance criteria • No red or yel...
I need a straightforward mobile app that runs smoothly on both iOS and Android. Its core job is to let me record every ice sale in seconds: • I select (or add) a customer and their pre-saved price per 1 kg, 3 kg, and 5 kg bag auto-fills. • I type the quantities sold and the app instantly shows the line total and the grand total. • At any moment I can open a dashboard that sums all sales: one view groups them by day, another rolls them up by calendar month. A small back-office screen must let me: – create, edit, or deactivate customers and their individual price lists; – correct any mistaken sale; – back up or export the raw table (CSV or similar). I’m open to your suggestion on the underlying data store—MySQL, SQLite, Firebase, or a...
Gamut Apps is building a women focused ride-sharing MVP. Our product is already about 60% complete. Our small team is looking for some additional help to complete the final 40% of the MVP. Our budget is $3000, and the project is entirely in Swift code. Our team consists of two developers, and a UX Designer, so a freelancer would have to be willing to work with the existing team to work towards the companies goals. 1. GPS tracking – priority one Real-time location updates must flow smoothly between driver and rider screens, updating the map every few seconds without hammering battery life. 2. Transactions Hook up Stripe (or a similarly robust payment gateway that you recommend) for payments, refunds, and fare calculation. 3. Driver’s-licence pass/fail gate A ...
I want a simple, reliable mobile application that lets me capture, organise and complete my daily tasks wherever I am. The app must run smoothly on both iOS and Android, so a cross-platform framework such as Flutter or React Native makes sense, but I am open to your preferred stack as long as the final binaries install cleanly on recent devices. Core workflow • Add, edit, reorder and delete tasks in as few taps as possible. • Optional due date and reminder notifications so I don’t miss deadlines. • Visual status cues (e.g. colour or strike-through) for completed items. • Local data storage with an easy export or backup option; no server back-end is required at this stage. Deliverables • Source code and project files. • Test builds (.ipa for...

I plan to launch a native Android shop application and need the complete build, from UI to final Play Store–ready package. The core scope is clear: • User login and registration • Shopping cart • Payment gateway integration All three features must work together seamlessly, with clean navigation and a modern material-design look. Code should be written in Kotlin or modern Java and structured for easy maintenance, using Android Studio and standard Android SDK components. The finished work should include: – Source code in a Git repository – An installable APK for testing – Step-by-step build and deployment instructions If third-party libraries are used for the cart or payments, they must be well-documented and licensed for commercia...

I have a finished mobile game ready to reach players and I’d like an experienced hand to make sure everything is done correctly. . The goal is to get my game approved and visible in the store. That involves: • Verifying the APK/AAB, signing key, version codes, and target SDK so they meet Google’s latest requirements. • Uploading the store-listing assets I provide (icon, screenshots, feature graphic) or letting me know precisely what is missing. • Completing every Play Console form—content rating, privacy policy, target-audience declaration, pricing and distribution territories, testing tracks if needed. • Submitting the build and staying on board until Google flags the release as published with no policy warnings. The job is done when the gam...
The design files are final; now the UI must look just as flawless on devices as it does in Figma. I need every pixel, font weight, and micro-interaction implemented in Flutter so the mobile app behaves identically on both iOS and Android. Responsiveness across screen sizes, smooth 60 fps animations, dark-mode readiness, and adherence to Material / Cupertino conventions where appropriate are all part of “perfect” for me. Because this project is a UI build only, clean, well-commented Dart code and a clear folder structure are essential—I want to be able to hand the repo straight to the backend team without a refactor. Continuous delivery through Git (one small merge request per screen) will help keep review cycles short, and I’m ready to begin those reviews immediate...
I want to bring a new business-focused mobile application to life and release it simultaneously on both iOS and Android. The core of the project is straightforward: secure user login and authentication, a clean in-app purchase flow, and timely push notifications that keep customers engaged. You are free to work in native Swift/Kotlin, React Native, Flutter, or another proven cross-platform stack—what matters most is a smooth, bug-free experience that feels fully native on each platform. Strong attention to data privacy and store-compliant purchase handling is essential, and I value clear communication while we iterate on UI/UX details. Deliverables (all discrete): • Fully functional iOS and Android builds ready for App Store & Google Play submission • Source code wi...
I’m building a mobile learning app for school students in Odisha, so every screen and string must be available in Odia from day one. I’m open to either React Native or Flutter—whichever you feel lets you move fastest and stay maintainable—provided you have already launched at least one functioning app with it. Core scope The first release has to cover the essentials: secure user login / authentication, smooth in-app video playback that hooks to a simple backend or streaming service, and timely push notifications. Beyond that, I’d like an assignment-submission feature where learners can upload a file or photo for review. Deliverables • Cross-platform mobile app (Android primary) • Full Odia localisation (UI text and basic RTL/LTR consideratio...
