From 234,260 reviews, clients rate our iPhone Developers 4.9 out of 5 stars.I’m building a mobile application that guides users through their personal health-recovery journey. The vision is a clean, motivating space where people can set goals, log daily progress, and see their improvements over time. I’m still refining the final feature list, so I want a developer who can both advise on best practices and then turn the agreed scope into a reliable, cross-platform product. What the project needs • A polished iOS and Android build (React Native, Flutter, or native—open to your recommendation) with secure user accounts, cloud data storage, and push notifications. • An intuitive onboarding flow plus a dashboard that lets users record activities and track milestones with ease. • Clear, well-commented code and brief documentation ...

We are seeking an experienced mobile app developer to update and enhance our existing mobile application, available on Android (Java) and iOS (Swift/Xcode). The app is already live, and we are looking for a skilled developer to implement updates, fix bugs, and ensure smooth cross-platform functionality.
I want to bring a fresh social-networking experience to life and need a complete mobile app that runs smoothly on both iOS and Android. The core of the product is a robust User-profile system—think clean onboarding, editable bios, avatars, privacy controls, and a profile-to-profile follow mechanism. From sign-up to profile customization, everything should feel fast, modern, and secure. Cross-platform delivery is essential. If you prefer Flutter, React Native, or another proven framework that keeps one code-base in sync across the two stores, let me know your reasoning; I’m open as long as the final apps meet Apple and Google submission standards. Key requirements • Native-level performance and polished UI/UX that aligns with current iOS Human Interface and Android Mate...
I need an experienced mobile developer to take my business-focused app from concept to a live roll-out across the entire state. The product must launch on both iOS and Android at the same time so I can monitor adoption and performance region by region. Core scope • Build robust native or cross-platform code that meets current App Store and Google Play guidelines. • Implement a clean, secure user-profile system; no other social features are required at this stage, but the architecture should leave room for future additions such as messaging or a news feed. • Handle end-to-end deployment, including test flight / beta tracks, analytics hooks, and store submissions. • Provide clear documentation and a short hand-off session so my team can track progress and gather ...
We are looking for an experienced Flutter Developer to build a marketplace mobile application for buying and selling second-hand vehicles and spare parts. Project Overview: The app will allow users to: List and sell second-hand vehicles Sell and purchase vehicle spare parts Browse listings with filters Contact sellers Manage their listings Subscribe to premium plans for better visibility Technical Requirements: Frontend: Flutter (Android & iOS) Backend: Firebase (Firestore, Authentication, Cloud Functions if needed) Push Notifications (Firebase Cloud Messaging) Clean architecture and scalable code API integration if required Payment gateway integration for subscription model Subscription Model: Free basic listing option Paid subscription plans (monthly/yearly) Featured listings fo...
I’m building a new mobile app that helps users organise and complete remote tasks, and I need a cohesive set of realistic illustrations that will give the interface a polished, trustworthy feel. Each illustration should align with common in-app moments—onboarding screens, empty states, success messages, and quick tutorials—so users intuitively understand what to do next. Here’s what I have in mind: • Consistent style: clean, realistic visuals (no cartoon exaggeration) with a balanced, modern colour palette that translates well on both light and dark themes. • Mobile-first sizing: SVG or high-resolution PNGs optimised for scaling across multiple screen densities. • Seamless hand-off: layered source files in Adobe Illustrator or Figma so my deve...
I need a simple but fully-functioning booking app for home and office cleaning, built in Bubble, FlutterFlow, or any similar no-/low-code tool that lets us move fast with AI-assisted workflows. The cap for this first build is $100, so the scope must stay lean and focused on the core journey: • New users sign up with OTP verification • They pick a date, time, and address; GPS auto-fills their location and shows distance to the nearest cleaner • In-app chat opens instantly and includes a secure payment request the moment the job is confirmed • When the work is done, the client rates and reviews the cleaner On the back end I need a lightweight admin panel where I can approve cleaners, track every booking, release or refund payments, and moderate reviews. Acceptanc...
I already have every screen, interaction and data flow laid out in Figma Make. The prototype runs on a React frontend with a Supabase backend, and Figma recommends using Capacitor to wrap this stack for true-native deployment. What I now need is the full conversion, polishing and submission of that working prototype as production-ready apps on both the Apple App Store and Google Play. Scope of work • Rebuild the existing React + Supabase codebase inside a Capacitor shell so it compiles cleanly for iOS and Android. • Preserve every feature present in the current design—camera-gear cataloguing, frame-by-frame exposure logging, and one-tap export to CSV or PDF—exactly as it behaves in Figma Make. • Add secure email-and-password authentication via Supabase Aut...
I need a complete mobile solution that lets everyday users stay on top of their money every month. The core flow is simple: they enter income and expenses, assign each item to a spending category, and then review their progress through clear summaries and two key visuals—pie charts for category distribution and line charts for month-to-month trends. If you feel a bar chart could add value I am open to that, but it is not essential. The app must launch natively on both iOS and Android from a single codebase, so a framework such as Flutter or React Native makes the most sense. Clean, responsive UI, smooth onboarding, and secure local storage (or a lightweight cloud sync you propose) are critical. I will provide color guidelines and sample data; you handle architecture, implementation,...
I need a full-featured sports-betting application built natively for both Android and iOS. The app must let users place wagers on Football/Soccer, Tennis, Cricket and Baseball, with the flexibility to plug in additional sports later. Core experience Real-time match feeds should drive live odds that update instantly on screen, and users must be able to register, verify their identity, fund their wallet and withdraw winnings without leaving the app. Smooth navigation, push notifications for goals or set points, and rigorous security are non-negotiable. Payments Deposits and withdrawals have to work through Crypto, Visa/Mastercard as well as Google Pay and Apple Pay. I will supply the acquiring accounts and any necessary API keys; you will wire them into a single wallet system that auto...
UI/UX Designer Needed – Mobile Quiz App for Competitive Exam Preparation Project Overview I’m building a mobile quiz application focused on competitive exam preparation (for example exams conducted by Staff Selection Commission and medical entrance exams like National Eligibility cum Entrance Test). The app allows students to: Play quizzes with friends Create their own quizzes based on exam + syllabus Track performance, rankings, and learning insights Earn reputation and rewards Browse exams, syllabus, articles, and posts This is a dynamic app — all exams, syllabus, questions, and content are managed via a CMS. The UI must be flexible and data-driven. Target users: students preparing for competitive exams who want a social + analytical learning experience. Core ...
I need an AI chat agent built from the ground up to take over real-time customer service across a dedicated WhatsApp line. The bot must greet visitors instantly, understand their questions in multiple languages, and return clear, relevant answers without sounding scripted. When the query falls outside its scope, it should hand the conversation to a live agent smoothly while keeping full context. Key expectations • Seamless installation on my existing site (JavaScript snippet or widget) and connection to my verified WhatsApp Business account through the official Cloud API. • Natural, conversational responses in at least English and Spanish to start, with the framework ready to add more languages easily later. • A simple dashboard where I can upload FAQs, product manua...
Project Title Mobile-First Web App for Fuel Inventory & Blending (Multi-User) Project Description I am looking for a developer to build a mobile-first web application for fuel trading and blending operations. The application will be used daily by drivers, supervisors, and the management team, so it must be simple, fast, and practical to use on mobile phones as well as desktops. The core functionality includes product setup (diesel, furnace oil, used oil, etc.), tank-wise inventory tracking with multiple tanks per product, inward and outward stock entries, automatic stock balance updates, and a blending module that calculates total blended quantity and average cost per liter based on input quantities. Drivers should be able to enter delivery quantities and basic details, supervisors ...

I am ready to turn a clear productivity concept into a fully-functional mobile application built entirely in FlutterFlow. The goal is to launch one unified codebase that compiles cleanly for both iOS and Android, takes advantage of FlutterFlow’s visual builder, and keepshand-off to native code to an absolute minimum. Key scope The core screens are sketched out in Figma, and I will supply brand colours, fonts, and a simple user-journey map. You will translate these assets into FlutterFlow components, wire up state management, and integrate any third-party packages available inside the FlutterFlow marketplace (for example Firebase Auth, Firestore, or local storage) where they fit our workflow. While the main purpose is productivity rather than e-commerce or social networking, the a...
I’m commissioning a complete iOS application that mirrors an iPhone screen over AirPlay in crisp Full HD (1080p) with minimal latency. The build must respect Apple’s latest guidelines, use proven frameworks such as ReplayKit, AVFoundation, and Swift / SwiftUI, and remain efficient enough to keep CPU, GPU, and battery impact low on current iPhone models. AirPlay is the only protocol required and the app does not need to accommodate iPads. I expect the typical tap-to-connect flow, a clear indication of connection status, and graceful handling of interruptions (incoming calls, Control Center swipes, etc.). Animations should stay butter-smooth and audio, if routed, must stay in sync. Please send at least one example of a previous screen-broadcasting or similar real-time media app...
I’m building a cross-platform mobile app in Flutter and need help wiring up the NFC layer on each platform. On iOS the job is straightforward: when the user taps an NFC tag, the app should silently read the NDEF text record and present the payload on screen—nothing more, no writing required. Android demands a bit more. Besides reading tags in the same way, the app must also broadcast (beam) an NDEF text message so the IOS phone above or another Android phone can pick it up. A simple UI toggle to switch between “Read” and “Broadcast” modes is enough; the broadcast text can be hard-coded for now so I can change it later in code. Key points • Single Flutter codebase with platform-specific channels only where necessary • Use any well-maintai...
I’m ready to turn a real-world space into a fully interactive virtual tour and need a VR-savvy team that can own the entire build. The end product must feel natural inside a headset (Meta Quest, HTC Vive) yet remain just as smooth through WebXR in a standard browser. I will supply floor plans, 360° photos or reference imagery plus all copy; you take it from there—3-D modelling, scene assembly, interaction coding, light-baking, performance optimisation and final export. Unity, Unreal, Blender, RealityCapture or similar pipelines are all fine as long as the tour is stable, lightweight and easy for me to update later. Smooth navigation, subtle ambient audio, clickable info hotspots and a simple jump-to-scene menu are non-negotiable. Deliverables • Prototype build ...
I’m gearing up to launch a brand-new e-commerce application that will go live on both iOS and Android at the same time. The core goal is to give shoppers a smooth, secure experience from browsing to checkout, so code quality and UI polish matter just as much as feature completeness. Here’s what the first release needs to cover: • User accounts – email/phone sign-up, social log-in options, profile editing, order history • Product search – fast, keyword-driven querying with filters and sorting for hundreds of SKU entries • Payment gateway – fully PCI-compliant integration (Stripe, PayPal, or a comparable solution) supporting test and live modes A single, shared codebase with Flutter or React Native is perfectly acceptable, though I’m ...
I need to extract SMS messages from an iPhone. Requirements: - Experience with data extraction from iPhones. - Ability to securely handle and transfer sensitive information. Ideal Skills: - Familiarity with iOS and iPhone data extraction tools. - Attention to detail and reliability.
My logistics portal (Supabase + Vercel) used to feed a React Native app that drivers open through Expo Go, the two have stopped talking. Drivers see delayed, missing, and sometimes incorrect data; manifests, routes, and status updates never reach the device. I need you to jump into the private GitHub repo, trace exactly where the request/response chain breaks, and re-establish a dependable real-time flow between the portal and the mobile client. Once the fix is in place, please upgrade the project to the latest Expo SDK, verify that everything still works inside Expo Go, and then generate fresh production builds: • Android APK/AAB • iOS archive ready for TestFlight and App Store submission A brief smoke test should accompany those builds so I can confirm portal updates a...
I need a complete mobile application—Android and iOS—that lets private sellers list property either at a fixed price or in an auction format, much like eBay but strictly for real estate. Core flow • New users sign up with phone number verification only or social logins . • A seller chooses a package (Bronze, Silver, Gold or Platinum) before every listing, then uploads photos, videos, documents and a written description. • Buyers browse listings through search filters for price range, location and property type, switch between fixed-price and auction tabs, and place bids or make direct offers. • In-app chat and one-tap call buttons connect buyers and sellers instantly. I want a clean, modern UI, real-time bid updates, push notifications and a lightw...

I am planning a brand-new mobile application and need a developer who can take it from concept to a polished release on both iOS and Android. The idea is still flexible, so I value someone comfortable shaping requirements with me, suggesting the right architecture, and turning early sketches into an intuitive, stable product. Because there is no hard deadline, quality and thoughtful iteration matter more than speed. We can explore native Swift/Kotlin, Flutter, React Native—or whichever stack you feel will give us the best balance of performance, maintainability, and cost effectiveness. I would like source code hosted in a shared repository, regular builds I can test on each platform, and guidance on getting the final binaries into the App Store and Google Play. If you have a track ...
I have two intertwined features that must be polished and packaged for a smooth App Store submission within the next four weeks. First, the app streams both live and on-demand video; the video module is built around HLS and AVFoundation, so it has to pass Apple’s performance and network-usage checks. Second, the same build must offer live tracking that combines GPS location updates with background activity tracking; think CoreLocation plus Motion/HealthKit working together without draining the battery. The work covers final code adjustments, entitlement configuration, provisioning-profile setup, TestFlight distribution and a clean App Store build that is ready for review. Feel free to optimise UI details, but the core requirement is a release-candidate IPA that Apple will accept. D...
I’m ready to take my service-based business online and I need everything built from the ground up—the web platform and companion mobile apps. The scope covers both the backend and frontend of the website, any essential plug-ins, plus fully fledged iOS and Android applications that mirror the web experience. The core of the project is an online booking system. Clients must be able to see real-time availability, reserve a slot, and pay securely on the spot. Calendar integration, automated reminders, and payment processing are must-haves, not nice-to-haves. Here’s how I picture the rollout: • Responsive service website (frontend + backend) • Integrated booking engine with calendar sync, instant payments, and reminder automation • Native or cross-platfor...
Hi — we need urgent help with an existing mobile app project. We have a live Android and iOS app but lost access to the original source code. We only have APK builds and backend/admin access. We need an experienced developer who can recover from apk's etc and stabilize the project. We have a live Android and iOS app where the previous developer became unreachable. The client has full access to Firebase backend and Google Play/App Store accounts, but we don’t have the original frontend source code. We do have APK/build files and admin access. There is a critical login issue affecting users that needs immediate stabilization. After that, we want to rebuild a proper development pipeline and recover the project long-term. We’re looking for someone experienced in app ...
I have an existing mobile application that runs on both iOS and Android, and I now need a seamless integration with a third-party API. Your job is to wire the app to the new endpoints, handle authentication, parse the responses, and make sure everything is production-ready across the two platforms. The core tasks include: • Plugging the API into the existing codebase (both iOS and Android versions) • Implementing secure token or key management in a way that satisfies App Store / Google Play guidelines • Creating clean, reusable service classes or modules so future endpoints can be added easily • Adding thorough error handling, retries, and graceful fallbacks for poor connectivity • Writing concise in-code comments plus a short integration guide so my team ...
Users first visit a simple one-page website that directs them to download the Android or iOS website provides basic platform information, onboarding guidance, and community rules before redirecting users to the app download. After installation, they log in using their mobile number through OTP verification with automatic reading and auto-fill, next slide users complete a biodata form including name, groom/bride is profile for email, age, height, education, education, occupation, salary, city, contact details, family details and the system automatically creates their matrimonial profile with a unique Biodata ID. Users upload 2–4 photos, which are automatically watermarked with the community name and Biodata ID for secure identification, while images are securely streamed within the ...
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. Once we clear this immediate milestone together, you’ll roll straight into our regular sprint cycle, building new screens, integrating REST/GraphQL APIs, writing unit tests, and taking part in code reviews on GitHub. To get a quick read on your fit, please link to ...
1. Executive Summary & Project Vision We are looking for an expert Full-Stack Mobile Developer (or a specialized agency) to build a revolutionary Home Rental Application that fundamentally changes how users discover properties. The Concept: Traditional real estate apps rely on static grids and list views that cause decision fatigue. Our vision is to adapt the "Instagram Reels" or "TikTok" vertical scrolling model for property hunting. We want to create an immersive, full-screen browsing experience where users can "swipe" through high-quality property videos and images, making discovery rapid, engaging, and intuitive. 2. Detailed Scope of Work Your role will be to translate our Design Phase Guide into a production-ready mobile application (iOS & Andro...
I need a focused UI/UX case study that shows how a mobile app can help beginner gardeners succeed in tight urban spaces. The study should revolve around a single core feature—Plant Care Tips—and follow a minimalist, clean design language throughout. Please structure the work so it can be read quickly by stakeholders: • User persona: a concise one-page profile of a first-time, space-limited gardener. • User flow: a simple diagram showing how that user discovers and follows Plant Care Tips. • Low-fidelity wireframes: 4–6 mobile screens in Figma or Sketch that demonstrate the end-to-end flow. Keep visuals uncluttered and intuitive. • Design rationale: up to 500 words explaining key choices—layout, tone, typography, color—plus how each ...
I’m creating GreenThumb, a mobile app that helps city dwellers grow healthier plants with less guess-work. The first release must spotlight comprehensive planting guides—vegetables, herbs, and flowers—delivered in a clean, step-by-step format that adapts to the user’s zone, balcony size, and sunlight profile. Think quick-scan seed-to-harvest timelines, soil and container tips, plus in-app reminders that slot automatically into a personal planting calendar. Beyond the guides, I want basic tracking (photos, notes, growth metrics) and a light social layer where people can form or join gardening groups in their neighbourhoods. Group feeds should make it effortless to post progress shots, swap advice, and arrange informal seed swaps or rooftop meet-ups. Scope • ...

I need an iOS application that reliably mirrors the full iPhone and iPad screen to a television. The connection must work smoothly with Apple TV, Roku, and Chromecast so users can launch the app, pick their device, and see the display appear on the big screen with minimal latency and no cables involved. It should also work on any Android TV. Beyond plain mirroring, I also want to build in a simple remote-control overlay: once the TV feed is active, the phone should become a touchpad/remote for basic playback navigation (volume, play-pause, seek). iOS 16+ compatibility is required and the solution has to pass App Store review, so we’ll rely on native frameworks such as ReplayKit, AVFoundation, and the appropriate discovery protocols (AirPlay, DIAL, Cast SDK) instead of private APIs. ...
Project Description: I am looking for a professional and experienced app developer who can develop my Android app and successfully testing and publish it on Google Play Store by strictly following all Google Play Console policies, terms, and conditions.

I already have a Flutter user app paired with a PHP-Laravel back-end for an online food-delivery service. Two things still block launch: 1. Location on launch The app must grab the customer’s current GPS location every single time the app opens—no taps, no confusion. The latitude/longitude should flow to the Laravel API exactly as it does when the user manually selects their address today. 2. Checkout polish I need a careful pass over the existing Flutter checkout screen. Visual glitches, validation quirks or crashes that appear on either iOS or Android should be traced and fixed so payment and order submission run smoothly. When both items are solid, I want a clean build shipped live to the Apple App Store and Google Play. You’ll handle the store assets, provis...
I’m creating a native iPhone shopping experience and need a developer who can take it from wireframes to TestFlight. The app must let customers browse a full product catalog, add items to a persistent shopping cart, and check out through a payment gateway that supports Apple Pay or Stripe. For sign-in, I only want social media options—Apple, Google, or Facebook—so users can start buying with a single tap. You’ll receive finalized UI designs plus backend REST/GraphQL endpoints; your role is to build the Swift/SwiftUI front end, integrate the APIs and payment SDKs, and make sure everything passes App Store review. Deliverables • Xcode project with clean, well-commented Swift code • Product catalog, cart, and checkout flows fully functional • Soc...

I need a fresh set of eyes to run through the current TestFlight build of my iPhone app and make sure the on-device text and the storefront screenshots read naturally in every language we support. The job is intentionally small—about 20 minutes of focused work—so I’m expecting concise, high-impact feedback rather than a full linguistic audit. What to do • Install the build I’ll provide and switch your device language as directed. • Open the main screens covered by the App Store description and screenshots. • Spot anything that looks off: awkward phrasing, truncated strings, mismatched terminology, or screenshots showing the wrong language. • Jot down the exact string or screenshot name, a brief note on what feels wrong, and your suggeste...

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...
