    I’m creating a self-guided, two-hour tour that visitors can enjoy even when they have no signal, so every asset—audio tracks, video clips, map tiles, and imagery—must be packaged inside the app bundle and run 100 % offline once the first download completes.

    I need a pair of polished mobile apps—one for iOS, one for Android—that lets a traveler open the phone, find a human agent, and finish a booking in a few taps. The entire flow should feel like messaging a knowledgeable friend: the user starts a chat, describes the trip, then reviews flight and hotel options surfaced through live API feeds before paying securely inside the app. Core experience • Dual-platform build (iOS + Android) delivered either natively or with a single codebase such as Flutter or React Native—whichever you recommend for long-term stability and speed. • Real-time messaging between traveler and assigned agent, complete with push notifications and image/file share. • Integrated flight and hotel search tied to a major GDS/OTA API so a...

    Subject: Senior Full-Stack Mobile Engineer for Luxury Multi-Language Ride-Hailing Platform (Flutter / React Native) Hi Developers I’m launching a high-end private ride-hailing service tailored for a specific regional market, and I’m looking for an elite mobile developer to bring it to life. I’m not interested in a messy prototype or a generic, clunky template. The vision is to build something that feels genuinely world-class—fluid, visually stunning, and as effortless to use as Uber, but with a sharper, more refined aesthetic. The interface needs to be clean, intuitive for everyday users, and completely frictionless from the moment someone opens the app to when they complete a ride.

    I’m developing a mobile-first social networking platform that will run on both iOS and Android. Core features include profile creation, follower/friend connections, a real-time feed with likes and comments, private messaging, push notifications, and media upload for photos and short videos. A clean, modern UI/UX and smooth onboarding (email, phone, or existing social sign-ins) are priorities, and the codebase should be structured for easy scaling and future feature releases.

    I am looking for a UI/UX designer for ongoing part time work on a mobile app that is already live on Android and iOS. It has real users, so this is design for a product in use, not a concept from scratch. You would design in Figma and hand off to our in-house Flutter developers. You are not writing code, but you will be coordinating closely with them, so designs need to be clear enough that handoff is smooth and questions are rare. This is a long term engagement. I want someone who stays with the product for months and gets to know it, not one quick project. Schedule: this role runs in the evening. I need availability roughly 7 pm to 11 or 12 pm, IST, most working days. Total commitment is 10 to 15 hours a week. What we are looking for: 1. Mandatory: • Strong, conversational Eng...

    I need an app that mirrors Biyajkhata’s customer-management flow while running natively on both iOS and Android. The reference app already covers the core screens and logic, so your main focus will be recreating that experience and adding two important extras: • Key numbers panel – a quick snapshot of each customer’s outstanding balance, paid amount, and upcoming due date. • Universal name search – a fast search bar that lets users find any customer from any screen in real time. A cross-platform framework such as Flutter or React Native is fine, provided the final builds are smooth on modern and older devices alike. I’ll share Figma wireframes at project start; you’ll handle coding, basic UI styling consistent with Biyajkhata, and produce p...

The user flow is simple: type or paste a question such as “show me all orders placed this week,” tap a button, and instantly receive a correctly formatted SQL query. From there the query should be easy to copy, share, or save. Cross-platform consistency is essential, so the build must target iOS and Android from the same codebase. React Native or Flutter are both fine; feel free to suggest an alternative if it still produces App Store- and Google Play-compliant release builds.

    Sure. For Freelancer.com, I would keep it concise but make the **teaching requirement very clear**. ### Looking for a Mobile App Development Mentor – Android & iOS Quiz App I am a beginner and want to **learn how to build a simple MCQ/Quiz app for both Android and iOS**. I am looking for a freelancer who can **teach me step-by-step**, rather than developing the complete app for me. The basic app will have: - One question at a time - 4 answer choices - Correct/incorrect answer indication - Score calculation - Multiple questions/categories - Basic results screen I am open to **Flutter, React Native, or another suitable technology**, and would like your recommendation. I want practical, hands-on classes where I build the app myself while you guide me. I have limited/no programm...

    I want to create a full-featured JEE preparation app available on iOS, Android, and the web. The heart of the product is a robust Past Year Question (PYQ) engine where students can browse, filter, and take timed or untimed attempts at every previous JEE paper. After each attempt, the app should instantly show correct answers, detailed solutions, and performance analytics such as accuracy by topic, speed per question, and a projected percentile. While PYQ practice is the priority, I also need the architecture to accommodate two added learning modes: 1) custom mock tests that mimic the real JEE pattern and score calculation and 2) live or recorded video classes that can be scheduled, streamed, and replayed inside the same interface. These modules can follow once the core question engine ...

    Multiplayer Blind Wine Tasting App
    2 días left
    Verificado

    I’m building a cross-platform mobile game that turns a friendly blind wine tasting into an interactive experience on both phones and the living-room TV. Players pick an avatar—a bottle, glass, decanter or cork—and travel across two illustrated game boards: the Old World map (Germany, France, Italy, Austria, Portugal, Spain) and the New World map (Argentina, Chile, South Africa, New Zealand, Australia, USA). Core mechanics • Each turn a player answers a wine trivia card drawn from three difficulty decks worth one, two or three steps on the map. • The first to reach the final region wins, with the action mirrored on the TV so everyone can follow the race. Essential features • Wine scanning & database: when someone scans a bottle, the label dat...

    I want a lightweight, ad-free Android application that lets me look up UP Bhulekh land-records from my phone. The scope is deliberately small: the only in-app action is to search records by owner name and show the matching result exactly as it appears on the official site. A minimalist interface—logo, single search field, and a clean results screen—is all I need. You may implement it in Flutter or in native Android (Kotlin/Java). Under the hood you can either wrap the official website in a well-behaved WebView or call the public endpoints directly; whichever route you choose, the experience must stay fast and free of pop-ups or banners. No Play Store deployment is required. Just hand over: • A signed, install-ready APK • The complete, readable source code with basic...

    I need a full-stack solution that covers both the electronics and the software behind a 10 m air-pistol / air-rifle training target. Hardware – Design, program and calibrate an Arduino or ESP32-based PCB that detects each pellet impact, timestamps it and sends the raw x/y coordinates wirelessly. – Supply the firmware, pinout diagram and any Gerber or KiCad files so I can reproduce the board locally. Software The data from the target must appear in real time on an app that runs on iOS, Android and Desktop (Windows & macOS). A single codebase (Flutter, React Native, Qt or a framework of your choice) is fine as long as all four platforms are delivered. Core features • Live shot display with 10-ring scoring for both air pistol and air rifle distances • Ma...

    I need a polished mobile app that lets customers browse our menu, place an order, pay on the spot, and then follow their delivery in real time. The app must launch on both iOS and Android from day one, so I am open to native Swift/Kotlin builds or a cross-platform stack such as Flutter or React Native—use whatever you are fastest and most confident with. Core workflow • Online ordering tied to our existing menu and pricing • Secure in-app payments (card, Apple Pay, Google Pay) • Delivery tracking that updates the customer from kitchen prep through to arrival at their door Admin tools I’ll need an easy way to change menu items, prices, and availability without redeploying the whole app. A simple web dashboard or a Firebase/Firestore console would work fine a...

    I’m ready to turn my wire-framed concept—“Hyperlocal Adaptation vs. Global IP”—into a fully functioning mobile experience that runs on both iOS and Android from a single codebase. The build needs to cover user sign-up/on-boarding, push notifications, and three core screens: Home, Profile, and Settings. I will share the complete feature list and all design assets up front. State management must follow the Provider pattern; navigation should combine tab, drawer, and stack flows in the way that feels most natural to the journey. Clean, well-structured code is a must, so please organise folders, keep components lean, and document anything that isn’t obvious. Flutter (Dart) or React Native (TypeScript) are both acceptable—choose whichever lets you ...

    I have a production Flutter app that needs light but regular attention. The immediate focus is on two areas: polishing the UI/UX and squashing minor bugs that users are reporting. UI/UX work • Refresh the existing buttons and icons to match our updated style guide—assets are ready, you will wire them in and confirm they render crisply on both Android and iOS. • Tidy up the screens so layouts respond gracefully from small phones through to tablets. I’ll provide Figma references; you make the widgets flex accordingly. Bug fixes I will share a short list of reproducible issues (mostly navigation glitches and the occasional state-management hiccup). You trace, patch, and commit tests to prevent regressions. Workflow Code lives in a private Git repo; all work mu...
