Conform celor 347,056 recenzii, clienții îi evaluează pe Android Developers cu 4.9 din 5 stele.I am starting a multi-phase project to build a scalable voice-chat room application for Android, and I want Phase 1 completed first. The core stack is Flutter for the client, Firebase for auth, real-time audio and data, and a clean, modular architecture that can grow into later features such as Coins, VIP, Gifts, Agency, Family and Rankings. Mobile OTP login is my top-priority authentication method, though Google sign-in must also work smoothly. Every build needs to be pushed to a private GitHub repository that sits under my own account; I retain full ownership of all source code, server instances and databases. Phase 1 scope and deliverables • OTP and Google authentication • User profile creation & editing • Create / join voice rooms with room-wide audio &bull...
I need a smartphone-first web application that lets companies actively promote and track motorcycle safety for employees who ride on and off the job. The entire interface should be optimised for mobile browsers or packaged as a PWA, so every feature must feel native on a phone screen. Core workflow • Employees sign up or sign in with a simple email-and-password flow; all subsequent sessions remain authenticated until they log out. • Once logged in, the app starts real-time tracking of each trip (distance, speed, route), storing data in the back-end so managers can later view aggregated safety statistics. • In-app safety tips and short training modules appear contextually—either after a ride or when a risky pattern is detected—to reinforce safe habits. &b...

My Android app is sitting at a stable beta stage and now I need hard numbers on how it really performs in the wild. The focus is strictly on performance testing—specifically, I want clear insights into load-time behaviour and network efficiency across a range of devices and connection types. Battery usage can stay on the bench for this round. You’ll install the current beta (APK + ProGuard mapping provided), design meaningful test scenarios, then capture and interpret metrics with tools such as Android Profiler, Firebase Performance, or any other stack you’re comfortable with. Raw data is only half the job; I also need concise, prioritised recommendations that my dev team can act on quickly. Once we’ve implemented the agreed fixes, I would value your help preparin...
I want to create a modern property marketplace that gives Sri Lankans the slick, intuitive feel of realestate while being tailored to our own market realities. The most critical audience for launch will be local buyers and Sri Lankans living abroad, so every interaction has to feel fast, trustworthy and easy to use wherever they are in the world. For local buyers, the platform must open with rock-solid property search and filtering—location radius, budget sliders, bedrooms, new-build status, the works—delivered instantly and ranking results intelligently. I’d like clean map views, saved searches and push notifications baked in from day one. The project itself breaks down into four concrete deliverables: • Responsive public website • Full-featured iOS app &...
I’m in the final stretch before launch and need a seasoned QA engineer to put fresh eyes on the full product suite—native iOS, native Android, and the accompanying web application. Your mission is to uncover anything that could spoil a first-time user’s experience or threaten stability once we scale. Here’s what I expect to be covered: • Test suites: Functional, usability, performance, and unit tests that exercise all critical paths and edge cases. • Focus areas: User-facing interface polish, security loopholes (authentication, data in transit and at rest), and end-to-end data-integrity checks across devices and the cloud back-end. • Reporting: Clear, reproducible defect logs with screenshots, video or stack traces where relevant, severity taggi...
I am expanding the mobile team at Mux Digitals and need a passionate Flutter engineer to work with me in our Multan office on a full-time, onsite basis. The day-to-day focus will be building and maintaining cross-platform applications with Flutter and Dart, writing clean, testable code, and collaborating closely with designers and backend developers to ship new features on a steady cadence. Your primary strengths should be: - State management - API integration - UI/UX design Provider is our state-management approach of choice, so solid, real-world experience with it is important. Familiarity with Firebase services as well as the app-store and Google Play submission process will earn extra credit. The work involves iterating on existing apps and spinning up green-field modules, rev...
I’m creating an end-to-end digital presence for a friend’s transport business and need a partner who can deliver both a customer-facing website and twin native apps. The core flow is simple: a user enters pick-up and drop-off points, instantly sees the price for either local deliveries or intercity transport, and confirms the booking in a few taps or clicks. Once that foundation is solid, I’ll share additional requirements and copy, but right now I want to lock in the team that can build a clean, scalable version-one. Scope at a glance • Two native mobile apps — one for iOS, one for Android — backed by a shared codebase or separate projects if that suits your workflow better. • A responsive website that mirrors the app experience so customers ca...
My Android app is fully built, tested and already aligned with Google Play guidelines. What I now need is a smooth, end-to-end submission to the Play Store. You’ll log into the Play Console, set up a compelling store listing and push the first production release live. I answered “Yes” to needing help with the listing, so please handle every public-facing detail—app name, long and short descriptions, graphics, screenshots, content rating and policy declarations. I can supply raw assets (AAB/APK, icon, artwork) and any text you need; you refine, format and upload them so they pass review the first time. Deliverables • Complete Play Store listing created and populated • App bundle uploaded with correct signing and versioning • All compliance form...
I need a small utility that sits on my Android phone and repeatedly performs a simple swipe gesture in the game I’m playing. The motion never changes, so a loop that keeps firing until I manually stop it is enough— no timers, no condition checks. You’re free to implement it as an APK with Accessibility Service permissions, an ADB script, or any other lightweight approach that keeps the device un-rooted and lag-free. All I really care about is: • I enter or edit the start- and end-coordinates (or drag to record them), • I press Start and the swipe repeats smoothly, • I press Stop and it halts instantly. Hand me the finished build or script with a brief note on setup and I’ll test it right away.
I need an end-to-end ordering and last-mile delivery solution built from scratch. The scope covers three tightly-integrated products, each delivered with production-ready source code, clean UI and full documentation. • Native consumer apps (Android & iOS) – Product catalogue with offers and promotions – Cart, secure checkout and payments via credit/debit cards, mobile wallets, Apple Pay and Google Pay – Real-time order tracking and rich push notifications • Web-based admin panel – Catalogue, inventory and pricing control – Live order management, refunds and analytics dashboards – Campaign manager to send targeted push notifications for offers or promotions • Driver Android app – Update delivery stat...
I need a clean, intuitive mobile app that lets my café customers order and pay before they even arrive. The core of the project is online ordering, and I want three specific features working flawlessly from day one: • Menu browsing that syncs with our daily specials and lets users customise items • Real-time order tracking so customers can see exactly when their drink will be ready • Secure payment processing with the usual card and wallet options, plus the ability to add promo codes My priority is a smooth, bug-free user experience that looks on-brand and loads fast on both iOS and Android. You are free to choose the tech stack you’re most comfortable with—as long as it supports future loyalty add-ons and integrates cleanly with our existing POS...
I need a developer who can replicate Meta’s system-level “floating overlay” on HorizonOS by creating an independent app that shows a WebView on top of any screen. This WebView will act as a HUD: it must load any URL I specify at runtime and display it without back, forward, or refresh controls. What makes the job tricky is that the original overlay relies on Meta’s private APIs. I already have the device rooted and running USERDEBUG, so full adb, shell, and file-system access are available. Your job is to: • Analyse the stock overlay APK (it is unencrypted and easy to decompile) to discover the required libraries, services, and signature checks. • Re-implement the floating interface using those same libraries so the new APK is accepted by the system....
I am looking to develop a private, single-seller B2B pharmaceutical ordering and delivery application for my business, with an Web + Android-first approach. This is not a multi-vendor marketplace; only our company’s products will be sold through the platform, and deliveries will be handled exclusively by our in-house drivers. The key modules required for the project are as follows: 1. Retailer Android App * Trusted chemists/retailers can log in securely. * View our inventory uploaded through Excel/CSV files. * Place orders directly through the app. * Access pricing and available stock information. 2. Delivery Driver Android App * Daily delivery routes and orders assigned to drivers. * Order status updates and tracking. * Digital Proof of Delivery (OTP and/or Signature capture). 3....
I need an experienced developer to turn my concept into a fully functional mobile application. The focus is strictly development-related—the UI designs will either be supplied later or refined together once the core build is stable, but my immediate priority is getting the app itself working smoothly on both iOS and Android. Here’s what I’m aiming for: • A clean, well-structured codebase (Swift / Kotlin or a cross-platform framework such as Flutter or React Native—open to your recommendation). • Core features implemented exactly as documented in the user-flow I’ll share after kickoff. • Secure user authentication, basic in-app data storage, and API integration with my existing back-end. • Source code pushed to a private Git repo with...

You will build a 100% offline Android demo app (no server/API needed) that implements: GPS location collection 2.Real-time route/trail drawing on a map Only candidates whose demo passes our background location stability test will receive the full detailed requirements. Demo must include source code, build instructions, and a short video demonstrating the background tracking working on locked-screen, background running and battery-saving modes of major Chinese Android devices (Huawei, Xiaomi, OPPO...
I need a straightforward utility app built from the ground up for both iOS and Android. The single must-have feature is seamless data synchronization, so users can start a task on one device and pick it up instantly on another without friction. I’m open to the framework you prefer—Flutter, React Native, or Kotlin Multiplatform—so long as the final binaries meet current App Store and Google Play requirements and performance feels fully native. Clean, well-commented source code and basic UI/UX that follows each platform’s guidelines are essential. Deliverables I expect: • Wireframes or mock-ups for approval • Source code in a private repository • Test builds for both platforms • Final release builds ready for store submission •...
I’m ready to commission a full-stack mobile application that lets households in my town find, compare, and book local electricians, plumbers, and general handymen— all from one place on both iOS and Android. Core experience The app must read a user’s location and instantly surface tradespeople who are not just nearby but actually available in real time. From there, users should be able to pick a time-slot, confirm the job, exchange messages, and pay without leaving the interface. Push notifications and automated reminders need to keep both sides on schedule. Messaging & reviews After each job, customers leave a verified review that becomes part of the tradie’s public profile. Those ratings, plus previous chat history, help future users decide quickly and...
I need a detail-oriented tester to focus exclusively on the load-time performance of my new mobile game. Your task is to open every screen, level, and menu on both fresh installs and returning sessions, then capture precise timing data so I can see where players might be kept waiting. Please work with at least two different devices and OS versions (Android and/or iOS), use any standard profiling tools you prefer—Android Studio profiler, iOS Instruments, or even Firebase Performance Monitoring—and record the exact steps that reproduce slowdowns. Screen-recordings or GIFs alongside raw timing logs are essential, as I want to pinpoint what happens before the splash screen, between screens, and during level transitions. Deliverables I’m expecting: • A table of measur...

I’m ready to build an MVP that lets backpackers, locals and every kind of traveller post and browse honest reviews of hostels, hotels, restaurants and must-try dishes. From day one the product has to live on the web plus native iOS and Android apps so the same account follows a user wherever they go. Key functionality I need in this first release: • Robust user reviews and star ratings attached to places and dishes • Easy social-media style posting so travellers can share photos and tips straight from their phone • Real-time messaging between members for meet-ups or quick questions Account creation must feel effortless, so you’ll wire up three entry points: classic email/password, one-click Google or Apple ID, and popular social networks (Facebook, X/Twit...
I’m ready to launch a new social networking platform and need both a responsive website and native apps for iOS and Android developed in parallel. Core experience I’m after: • Secure account creation with rich user profiles (photo, bio, interests, privacy controls). • Real-time one-to-one and group messaging; typing indicators, read receipts, push notifications, the usual emojis and media attachments. The visual style should stay clean and intuitive, with a layout that translates naturally from desktop browser to mobile screen. I’m open to the stack you feel most confident with—React / React-Native, Flutter, Swift + Kotlin, or another proven combo—as long as the final build is performant, easy to maintain, and well-documented. Please fac...
I need a complete system that can turn data written in the ancient Brahmi and Sharda scripts into a scannable, QR-style matrix and then read it back reliably. The work splits into two tightly linked parts: 1) Pattern engine Build an algorithm that takes Brahmi or Sharda text (Unicode strings supplied by me) and outputs a square, high-contrast image resembling a QR code. Include error-correction logic so the pattern survives moderate camera tilt, blur, and 20 % visual noise. A lightweight CLI or library in Python, Java, or C++ is fine as long as I can call it from other projects later. 2) Dual-platform scanner Create an app for both iOS and Android whose main task is to scan and decode these patterns. After scanning, the screen should show an informative read-out: the detected script,...
This project covers the full build of a hyper-casual puzzle game for Android, structured across 20 bite-sized levels. Gameplay should revolve around a single-tap or swipe mechanic that players can understand in seconds but still find progressively challenging. I envision bright, cartoonish visuals—clean lines, lively colors, and playful character or object animations that instantly read well on mid-range devices. Core scope • Design concise puzzle mechanics, then scale them logically so each new level introduces a fresh twist without adding complex rules. • Create all 20 levels, balanced for difficulty and session length (under one minute for early stages, up to two minutes for later ones). • Produce lightweight cartoon-style art assets and UI that match current hyper...
I’m ready to release the first cut of my cross-platform fitness application and need it built in Flutter so it ships simultaneously to iOS and Android. The scope is intentionally lean: just the essentials that prove the core experience works while leaving room to layer on advanced capabilities later. Core flow • Secure email-and-password signup and login wired to Firebase Authentication. • A workout video library screen fed from a simple Firestore collection (no complex categorisation yet). • A personal profile where users can: – set fitness goals, – track workout history, – and update their basic information. • Clean, maintainable Flutter code with state handled predictably (Provider, Riverpod or Bloc – I’m open ...

Necesito desarrollar una aplicación web optimizada para Android cuyo objetivo principal sea la gestión de tareas. Quiero que el usuario pueda crear, editar, marcar como completada o eliminar una tarea desde su teléfono sin instalar nada desde la Play Store; bastará con abrir el navegador o anclar la app a la pantalla de inicio. Busco, por tanto, una solución tipo PWA o similar que: • cargue rápidamente y se adapte bien a distintos tamaños de pantalla Android; • funcione con conexión limitada (caché básica u offline-first); • incluya autenticación de usuarios y sincronización en la nube para mantener la lista actualizada entre dispositivos. Me interesa un diseño limpio, intuitiv...
I’m ready to launch a fresh Android-only marketplace where users can trade both physical and digital items from a single, intuitive mobile experience. The core of the first release is solid user profiles that let sellers manage listings and buyers track favourite items, messages, and purchase history. Here’s the flow I have in mind: a new user signs up, creates a profile, and can immediately post an item with photos (or upload a digital file), set a price, and choose basic shipping or direct download. Other users browse, filter by category or keyword, open the seller’s profile for credibility, and then move forward with the transaction. For now, payment handling will be kept minimal; we can discuss whether to start with a simple cash-on-delivery or voucher code approac...
Perdí por completo el código fuente de mi aplicación Android y solo conservo el APK instalado en algunos dispositivos. Necesito recuperar un proyecto íntegro en Android Studio a partir de ese binario, con todo el código legible, los recursos ordenados y la posibilidad de compilarlo sin errores. La app hace un uso intensivo del teléfono (gestión de llamadas y sensores) y precisa acceso al GPS para su funcionamiento principal, por lo que el proyecto resultante debe conservar esas llamadas a la API de Android tal como funcionan hoy. El trabajo consiste en: • Descompilar el APK con herramientas como JADX, apktool o equivalentes. • Reconstruir la estructura del proyecto (módulos, Gradle, recursos, firmas). • Limp...
I need an Android application that lets one phone push and pull content to another phone, and from a phone to an Android-based TV, entirely over Bluetooth so it works even when there is no internet or Wi-Fi. The app must cope with any files I throw at it—photos, videos, documents, APKs, ZIPs—while giving the user a simple, modern interface to pick, send and receive them. App required for Android TV, Mobile, Tablet etc Core flow • Device discovery and pairing happen inside the app, with clear permission prompts that follow Android 9+ requirements. • After pairing, the sender selects one or many files of any type; the receiver confirms; a progress indicator shows speed, remaining time and success or failure for each item. • Transfers should resume gracefully...
I need twelve Android users to help me measure how my app affects battery life during heavy, real-world use over a 14-day window. The sole focus is performance, specifically battery usage when the phone is under high-usage pressure—think continuous video streaming, navigation, gaming, or other power-hungry tasks. What you’ll do • Install the latest build from Google Play (link provided after hire). • Use the app for at least two hours each day while your device is already running another intensive activity. • Capture screen recordings or annotated screenshots that show battery percentage at the start and end of every session. • Export Android battery stats and simple logcat excerpts once daily (I’ll share clear, step-by-step instructions&mdash...

I’m refining an Android/Web strategy management sport game that’s already playable, but its first-time user experience and long-term engagement need a serious lift. Your task is to give me hints abount the UX so players understand the core loop quickly, feel rewarded early, and keep coming back day after day. What I already have • A functional build on Google Play (test APK will be shared) and a web version • Basic flows for tutorial, lobby, battle, and rewards • Analytics showing drop-off after the first 7 minutes and retention dipping below 20 % D1 What I need from you • A concise audit pinpointing friction points during onboarding and mid-session moments • Fresh interaction patterns and screen layouts that make the core mechanics intuitive...
I am building Nova Marketplace, a peer-to-peer classifieds platform that must run smoothly on both iOS and Android. The core idea is simple: let users post items, chat, and arrange cash-on-delivery deals in a clean, trustworthy space. Key screens and flows • Onboarding – sign-up is by phone number only; an SMS code confirms the account and a profile photo is mandatory before anyone can act. • Home – search bar, category carousel, most recent ads, and an always-visible “Publier une annonce” button. • Ad creation – multiple photos, price field, and rich-text description; ads are sorted under categories like Téléphones, Jeux vidéo, Vêtements, Véhicules, Services, etc. • Private messaging – use...
I need a full-featured web application that streamlines every day at my coaching management institute. At its core the platform must let new and existing students register online, let us manage classes and batches with an easy course-scheduling calendar, and process fees securely. Beyond those basics, the app has to feel like an online learning hub: each class session should generate a live recording that students can replay later, and every course needs a repository where we can upload notes, slides or any other study material. Each learner, teacher and admin will sign in to a role-based dashboard—students see their own timetable, recordings, materials and payment history; teachers can manage the courses they handle; administrators get full oversight and reporting. Key delive...
I’m building a single, cohesive inventory management system dedicated to DIGITAL products and I want it available everywhere my team works—browser, iOS/Android, and desktop. The core feature set is already defined: effortless product listing, real-time order tracking, and clear reporting & analytics that highlight stock levels, sales velocity, and low-inventory alerts. Here’s what I picture: a modern, responsive front end (React, Flutter, or similar) talking to a secure REST or GraphQL API, backed by a relational database that can scale. The application should recognise digital-only nuances such as licence keys, download limits, and instant fulfilment, so workflows differ slightly from a physical-goods catalogue. Role-based access is essential, and I’ll need ex...
