I need a reliable developer to turn my idea into a functional Android application. At this stage I only require a simple, well-structured MVP that can later scale as new features are defined. Key needs: • Build a clean codebase for Android (latest SDK, Kotlin or Java—whichever you prefer). • Implement a straightforward UI with basic navigation and placeholder screens; final visuals can wait until the next phase. • Set up fundamental app architecture (MVVM or similar), user input forms, and local data storage so I can see real interaction on a device. • Provide clear instructions for running the project in Android Studio and generating an APK. I have not locked the app’s exact purpose yet, so I’m looking for someone who can advise on best practi...

TECHNICAL SCOPE DOCUMENT: "Super App - Driver's Virtual Assistant" 1. Introduction & General Objective The project consists of developing a mobile application focused on financial management, safety, and automation for ride-hailing drivers (Uber, Lyft, InDrive, etc.). The app will run in the background as a "co-pilot", reading screen data to calculate ride profitability in real-time, manage operational costs, and ensure driver safety through intelligent audio recording and emergency alerts. 2.

Recommended Tech Stack: Kotlin (Native) or Flutter (with a strict requirement for native Method Channels to handle background services and permissions). Data S...

I need the TikTok SDK added to both the Android and iOS versions of my mobile app so I can pull accurate in-app analytics from TikTok’s dashboard. The focus is strictly on analytics events (no login or video-sharing features). Alongside the SDK setup, I also want Appsflyer integrated and configured so the attribution data and TikTok event data line up for clear cohort reporting. Both projects already compile and ship; you will be dropping in the SDKs, wiring the events, and confirming everything reports correctly in the respective dashboards. Key deliverables: • Add the latest TikTok analytics SDK to the existing Android (Kotlin/Gradle) and iOS (Swift/Objective-C with CocoaPods) codebases. • Map and fire the agreed-upon event list (installs, opens, purchase funnel, and ...

I need a straightforward Android application that lets users collect virtual coins by watching ads served through AdMob and Facebook Audience Network. Once enough coins are earned, the user chooses whether to spend them on Instagram likes, views, or followers. The moment an order is placed, the quantity selected must travel automatically to my SMM-panel account through its API so that fulfilment is completely hands-free on my side. I already have the panel; the app only has to send the right call and display real-time order status back to the user. Key flow • Show rewarded video or interstitial ad → credit coins. • Keep a running coin balance on device and server. • Let the user pick “Likes”, “Views”, or “Followers”, enter t...

Tecnologías sugeridas Kotlin o Java, Android Studio, Firebase (si se requiere backend ligero). Entregables mínimos 1. Código fuente bien c...

I need a lightweight Android application that can reliably record both-party audio on voice calls. The main goal is personal archiving, so clarity of the captured sound on each side matters more to me than fancy UI touches. Target devices My day-to-day phones are Oppo, Vivo, Redmi and OnePlus models running recent Android builds (I can ship a test handset if that helps). The finished APK should install cleanly and work without root on those brands; if a minimal permissions tweak or foreground service is unavoidable, let me know early so I can approve it. Required feature set • Two-way call recording that survives the manufacturer’s call-recording blocks and new Android privacy changes. • An in-app call history log showing date, contact/number and recording length, w...

I want to create a brand-new productivity app for Android, starting completely from scratch. I have no existing codebase, designs, or technical documents, so I will rely on your guidance to shape the project from concept to a working APK. Here is what I need: • An initial discovery call to refine the core idea, target users, and feature list. • Wireframes or rough screen sketches so we can agree on the user flow before coding begins. • Android app development (Java or Kotlin) focusing on clean architecture, responsive layouts, and smooth performance on current OS versions. • Basic productivity features such as task creation, editing, and simple reminders—enough to demonstrate real utility without overcomplicating the first release. • Simple local d...

I need a mobile application that lets me watch my CCTV system in real time and review recorded footage from anywhere. The app has to run smoothly on both iOS and Android and should connect to my existing NVR/DVR or IP cameras over a secure, encrypted channel. Location Preference: Developers based in Bangalore, Karnataka are preferred. Core scope • Live View: a low-latency stream that opens quickly every time. I am open to your advice on extras such as multi-camera grids, PTZ control, or motion-triggered push notifications if you have proven approaches. • Playback: scrubbing through the timeline, pausing, and jumping to specific times must feel instant and intuitive. Fast-forward, rewind, bookmarking, and clip export are features I would consider once the basics are in place. T...

I’m creating an Android-only application and need a developer who is equally comfortable in native Android (Java/Kotlin) and Python. The main objective is to connect a set of existing Python scripts to a clean, responsive Android front-end so the logic runs directly on the device. Here’s the current state: • All Python functionality is already written and tested on desktop. • No Android code exists yet; you will design the UI and wire it to the Python layer. • The bridge can be Chaquopy, Kivy, BeeWare, or any approach you prefer, provided performance on recent Android versions stays smooth. Scope of work 1. Set up the project structure and integrate the Python modules so they compile into the APK. 2. Build a minimal Android interface: a sin...

I’m building a mobile application that lets two users connect over a live video call on Android. The goal is a smooth, low-latency experience that feels as immediate as a phone call, only with video. Here’s the flow I have in mind: a user logs in, selects a contact, hits “Call,” and the peer instantly receives an incoming-call screen. Once connected, both parties can mute audio, switch cameras, or end the session. The call must automatically adapt to changing network conditions and recover gracefully from brief drops. WebRTC is my preferred technology stack, but if you can justify another approach with equal or better quality and device support, I’m open to it. Please leverage native Android (Kotlin/Java) rather than a cross-platform wrapper; I want full...

I need a complete mod-menu APK for the Android version of Pixel Worlds. The menu must load in-game, overlay cleanly on every screen, and give me a framework where I can switch individual hacks on or off without recompiling. Interface & usability I want the UI to be fully customizable: colours, button order, and even the option to swap in my own theme files on the fly. A collapsible floating icon that can be dragged anywhere would be ideal, but I’m open to alternative overlay behaviours as long as the user can restyle every element. Stealth & safety Anti-ban protection is essential. Obfuscate critical hooks, randomise signatures, and include bypasses for the game’s integrity checks so the account can survive online play. If additional encryption layers or signature...

I’m ready to commission a complete Android-only utility application whose core purpose is secure, real-time messaging. I already have the concept and basic workflow sketched out; what I need now is an experienced mobile developer who can turn those ideas into a polished, production-ready APK and guide it through Play Store submission. Here’s the scope in plain terms: • Build a native Android app that opens quickly, registers users by phone or email, and lets them exchange text, images, and voice notes in one-to-one or small-group chats. • Implement end-to-end encryption with a well-maintained library (for example, Signal protocol or similar) so all conversations stay private by default. • Design a clean Material-you inspired UI; I have colour references and a s...

I’m ready to move my idea from notes and wireframes into a working mobile product that lives in both the Google Play and Apple App Store. Because the concept is still being refined, I’m looking for someone who can guide the entire process—from choosing the right tech stack (native Kotlin/Swift, Flutter, React Native, or another option you recommend) through to final store submission. Here’s what I already know I’ll need: • Two fully functioning apps that share a single codebase where practical, yet still feel perfectly at home on their respective platforms. • A clean, modern interface and smooth onboarding flow; whether you build the UI from scratch or adapt an off-the-shelf kit is up for discussion as long as it looks polished and performs well. ...

I need a complete social networking experience built exclusively for Android. The project starts with user registration (email, phone, or Google sign-in) and moves through profile creation, a scrolling feed for posts, reactions and comments, and one-to-one chat with push notifications. I’d like a modern, Material-designed interface that remains fast on devices running Android 8.0 and up, and the finished package must be Play Store–ready. Kotlin and Jetpack libraries are my first choice, with Firebase (Auth, Firestore, Storage, Cloud Messaging) powering the back end, although I’m open to comparable solutions if you can explain the benefits. Deliverables at hand-off: • Clean, well-commented Android Studio project • Release-signed AAB/APK suitable for Play Cons...

I have an e-commerce concept and want it transformed into a polished Android mobile app that feels both stylish and intuitive. Core objectives • Build a native Android application focused on product browsing, secure checkout, and order tracking. • Craft an interface that looks clean, modern, and unmistakably premium—smooth animations, thoughtful spacing, and consistent typography are essential. • Integrate fundamental e-commerce features: searchable catalog, product variations, shopping cart, wish-list, multiple payment gateways, and push notifications for promotions and shipping updates. Technical expectations • Develop in Kotlin (preferred) or Java, following current Android best practices. • Use a scalable architecture (MVVM or similar), wi...

I need an experienced Android developer to turn my concept into a polished, production-ready app built natively for the latest Android SDK. I’ll provide the overall functionality goals during kickoff, but the visual direction must come entirely from a custom design created from scratch—no templates or off-the-shelf themes. Your process should cover UX wireframes, high-fidelity UI mock-ups, and the full Kotlin/Java codebase, all aligned with current Material Design guidelines while still feeling unique. Smooth performance, clean architecture, and well-commented code are essential because I plan to scale and maintain the app long-term. Deliverables: • Interactive Figma (or similar) design files • Compilable Android Studio project with source code • Signed re...

I want to turn my cab-booking idea into a polished mobile product that runs smoothly on both iOS and Android. The core requirement is straightforward: riders must be able to book a cab from their phone, watch the driver approach in real time, and handle payment without ever leaving the app. Because the project targets both major platforms, I am open to native builds (Swift + Kotlin/Java) or a proven cross-platform stack such as Flutter or React Native—whichever delivers the best blend of performance and maintainability. Whichever route you recommend, I expect feature parity across devices. Key functions I need from day one include: • Secure user authentication • Real-time ride requests and status updates (push notifications) • Live location tracking on an in-app ...

I'm a full stack developer looking for a commission-based sales partner. You bring clients, I handle all delivery. I build: Web Apps, Android (Kotlin), iOS (Swift), Desktop (macOS/Windows/Linux/Steam), AI Automation, Stable Diffusion pipelines, E-commerce, SaaS, CRM integrations, REST APIs. Your role: - Find clients from Upwork, Fiverr, Freelancer, LinkedIn - Handle initial client communication - Pass project details to me Your earnings: - 20% commission per project - Paid immediately after client payment received - No cap, no upfront investment needed - 100% remote and flexible

I want a complete Android-only social networking app built from the ground up and, just as important, I want to understand every step that goes into creating it. Your role will be two-fold: first, deliver a fully functional APK (plus clean, well-commented source code); second, walk me through your architecture, toolchain, and deployment process so I can replicate or extend the project later. Core expectations • Native Android build (Kotlin or Java with Android Studio). • Standard social features—user registration/login, profile editing, posts with images/video, likes/comments, and real-time notifications. • Secure back-end (Firebase, Supabase, or a lightweight REST API with SQL) and cloud storage for media. • Clear documentation: project setup, key code s...

I want to launch a dedicated Android social media app and need it developed from the ground up. The platform is Android only, so please focus on the latest Android SDK while keeping compatibility back to at least Android 8. I already have wireframes that outline a familiar social feed: users create profiles, follow one another, post photos or short videos, like, comment, and receive push notifications. Your role is to refine the UI to Material Design standards, build the front-end in Kotlin or Java, and connect everything to a scalable cloud back-end—Firebase is my first thought, but I’m open to an alternative you can justify. Robust authentication, real-time data sync, and basic content moderation hooks are essential. Performance, security, and clean, well-commented code will...

I'm looking for an experienced mobile app developer to create a social networking app for Android.

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 need a native-quality Android application that mirrors the core experience of my existing video-streaming website while adding mobile-first polish. The app must let viewers sign up, log in, and manage their own profiles, and it also has to give approved creators the ability to upload and share videos directly from the phone. Access to the catalog will be subscription-based, so the flow for choosing a plan, paying, and renewing has to feel seamless. We are onboarding a new Indian payment gateway (full REST API documentation is ready on my side) and I want that integration handled end-to-end—plan creation, recurring charges, webhook handling, and graceful failure states included. I am aiming for the standard streaming comforts: smooth adaptive playback, background audio, and se...

I want to create a brand-new programming language, purpose-built for full-stack web development. Think of the expressive ease of Python blended with the modern, modular feel of Kotlin—yet tailored from the ground up for today’s browser and server demands. Here is what I need from you: • A clear language specification that covers syntax, type system, standard library scope, and concurrency model. • A working reference implementation (compiler or interpreter) able to run real code on both client and server. If you choose to compile to JavaScript for the browser and target, say, a lightweight VM or Node.js on the back end, that works for me as long as the developer experience stays seamless. • Core tooling: lexer/parser, REPL, package manager basics, and a min...

I need a lean, battery-friendly Android app that can stream a smartphone’s GPS coordinates in real time. Once the user grants permission, the app should run as a foreground service, capture accurate latitude and longitude, and post them every few seconds to the REST endpoint I will provide. A small in-app Google Maps view must mirror the live position so we can confirm everything instantly. Please follow current Android 13 location-permission rules and make sure tracking survives reboots, Doze, and other battery optimisations. I will share the API spec; you may use Retrofit, Volley, or any modern HTTP client you prefer, as long as JSON payloads stay lightweight. Deliverables • Complete Android Studio project (Kotlin or Java) with well-commented code • Signed release A...

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 need a brand-new social networking app built natively for Android. The goal is to give users a smooth place to create profiles, add friends, share text, photos and short videos, and interact through comments and reactions—nothing bloated, just the essentials done really well. Scope of work • Design a clean, modern UI that follows the latest Material Design guidelines. • Develop the full Android application in Kotlin (or Java if you prefer) with responsive layouts for phones and tablets. • Build a lightweight backend (Firebase or another cloud solution you recommend) to handle authentication, real-time feeds, media storage and push notifications. • Implement basic privacy controls: block/report, public vs. private profile toggle. • Connect everyth...

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 ...

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 am launching a dedicated Muslim matrimony platform and need a full-cycle development partner to bring the product to life on both Android and iOS. The core build must cover: • Dual profile setup – users can register either as an Individual searching for a spouse or as a Guardian managing the search on someone’s behalf. • Robust search with age, location and education level filters so members can refine results quickly. • Three-tier match engine combining interest-based logic, profile-similarity scoring and manual “I like this profile” actions. • Real-time chat (text, emoji, attachments) secured with basic reporting/blocking tools. • Optional Guardian approval layer before conversations begin, configurable per profile. • Sub...

I’m looking for an experienced Android developer to step in and refine an existing native app. The core build is stable, but it still lacks a reliable, well-structured push-notification system. Your task is to review the current Kotlin/Java codebase, integrate (or repair) FCM-powered notifications, and be sure they respect the app’s current UX flows—no rogue alerts, no missed messages. Once the notifications are live you’ll help me run a quick round of QA on a small device matrix, package a signed release APK, and supply the updated source in Git so I can keep the repository current. Clean commits, clear comments, and a short README on any new dependencies will be part of the hand-off. If you’ve shipped native Android apps before and can demonstrate tigh...

I have a WordPress website with WooCommerce installed, where I sell both products and services. I want to develop an Android mobile application that works directly with my existing website as the backend. The app should fetch all data (products, services, user accounts, orders, etc.) from my WordPress WooCommerce setup using REST API. Important Requirement: I do NOT want any separate backend or additional hosting. The app must be fully connected to my existing WordPress + WooCommerce system and use it as the only backend. Main Features Needed: App should load data directly from my website Product & Service listing (from WooCommerce) User login / registration (connected to WordPress users) My Account section (orders, profile, etc.) Checkout integration (WooCommerce-based) App should...

I need a clean, production-ready mobile app that lets users create marriage bio-data profiles using both free and premium templates. A traditional and elegant visual style is essential—think subtle colours, classic typography, and a layout that feels refined rather than flashy. Core features I expect: 1. 3-Step Smart Wizard: A simplified form layout divided into categories (Personal, Family, and Career/Education) to keep the user flow clean and easy. 2. Automatic Draft System: Uses an offline Room Database to save all entered data automatically, allowing users to exit and resume later. 3. Dynamic Custom Fields: An "Add Custom Field" button in every section, allowing users to define their own labels (e.g., Gotra, Hobbies, or Social Media) and values. 4. 1 free and 10 Prem...

My Android app is already built and functionally complete, but it still needs a final round of refinement before I can release it. The focus is on two areas: tightening up the user interface so everything looks consistent and professional, and squashing the remaining bugs that occasionally surface during normal use. No major performance overhauls are required at this stage—just solid, reliable cleanup work. Alongside that polish, I also need a straightforward web-based admin portal. The portal’s primary purpose will be to let me view and manage core data from the app (think user records, content updates, simple analytics, and basic configuration toggles). A clean dashboard with standard authentication is enough; nothing overly complex for now, but it should be built with an ey...

All math problems, scoring logic, and screen-by-screen mock-ups are ready; the remaining step is transforming them into a smooth Android game and pushing it live on Google Play. The build can be in Java, Kotlin, Flutter, unity—whichever stack lets gameplay feel most responsive while keeping future updates straightforward. The visuals only need to replicate my mock-ups faithfully; you are free to optimise under the hood for performance and reduced APK size. Core functionality to implement: • Google Play Games Services leaderboard so students can compare scores. • Secure, device-synced progress tracking that survives reinstalls. • Simple multiplayer (turn-based or real-time) for puzzle races. Additional needs: • Automatic language switch based on t...

KnappIT is building a full-featured Multi-lingual AI conversational Legal assistant (Lity). I need someone who can take the idea from concept to a polished product that works seamlessly on iOS, Android, and the web. The assistant must handle both voice and text interactions fluidly: think high-quality speech recognition, natural-sounding TTS, and a chat interface that keeps context across devices. You’ll architect the back-end intelligence and then wire it to native mobile front-ends plus a responsive web app. Key deliverables • A scalable back-end (Python, Node, or comparable) exposing clean APIs for voice/text queries • Mobile clients for iOS (Swift/SwiftUI or React Native) and Android (Kotlin or React Native) plus a browser-based interface • On-device wake-wor...

I want to release a lightweight companion app for eFootball fans that runs natively on Android and focuses exclusively on rich player profiles and performance stats. The goal is a smooth, modern experience where users can browse, search, and favourite players, then dive into up-to-date attributes, season numbers, and historical records. You will handle the complete Android app development cycle: coding the UI in Kotlin or Java through Android Studio, wiring it to the data source I provide (JSON/CSV or a simple REST API), and packaging a signed APK ready for the Play Store. Clean architecture, material-style design, and efficient local caching are important so lists feel instant even on mid-range devices. Deliverables • Fully functional Android APK • Complete, well-commented s...

I want to make a website like parimatch where people can use and bet on their team

My Android application is already live, but a lingering bug keeps mis-displaying the user’s Name and Referral No. I need an experienced Android developer who can dive into the existing codebase, trace the root cause, and push a clean, well-documented fix to Git (or your preferred VCS). Scope of work • Review the current Kotlin/Java code (the project uses standard Android Studio tooling). • Identify why the Name and Referral No. are not updating or showing correctly. • Implement a solid fix, test it across the latest Android OS versions, and supply an APK or bundle for verification. • Leave concise inline comments so future maintenance is straightforward. Deliverables 1. Updated source code with the bug resolved. 2. A brief change-log summarising what was altered...
