I already have a live Flutter app and an active AdMob account. I now want Google AdMob Native (In-Feed) ads woven into my main listing feed, very similar to the way OLX sprinkles promotions between items. Here’s the flow I’m aiming for: after every five feed items a native ad should appear, matching the app’s current look and feel so users experience it as part of the content rather than a banner. I do not yet have the specific Native ad-unit ID, so I’ll need you to walk me through creating it in the AdMob console and wiring it up in code. The project is straightforward: plug the Google Mobile Ads SDK into my existing Flutter codebase (Dart), build a widget that pulls and renders the Native ad, place it in the list adapter, then verify that test ads show up reli...
I need a developer who can take our existing whole-home scent diffuser hardware and give it a fresh, branded mobile experience on both iOS and Android. The current units already pair over Bluetooth and can switch to Wi-Fi once configured; the new app must replicate that connectivity, then layer in a cleaner interface and a few extra smarts that set us apart from the generic software we use today. Core features we have in mind: • Customizable scent schedules that let users pick days, times, and intensity levels • Real-time usage statistics so homeowners can see oil consumption and filter life at a glance • Full remote control—start, stop, boost, or mute a diffuser from anywhere once Wi-Fi is enabled The firmware and protocol documentation are ready, and I can su...
I need a fully featured casino experience that launches simultaneously on Android and the web. The core catalog should open with two classic options—slot games and card games—plus a cricket-themed title to appeal to our local fan-base. Real-time play is essential, so the architecture must support live multiplayer tables and rooms with low-latency communication. Players must be able to transact seamlessly through in-app purchases, and talk to one another via integrated text chat during matches or spins. A single-codebase approach (e.g., Unity, Flutter, or similar) that compiles cleanly for both targets is preferred, provided the final builds feel fully native on each platform. Back-end services need to handle secure user accounts, RNG-verified game logic, payment processin...
Project Goal Build a mobile-first digital payments app that allows users to send, store, convert, and spend crypto-backed USD with extreme simplicity, comparable to Zelle or Venmo — while crypto remains largely invisible to the user. Core Principle: “It should feel like a normal money app, powered by crypto in the background.” ⸻ Target Platforms • iOS • Android • Backend server • Admin dashboard (web) ⸻ Core MVP Functionality 1. User Authentication Required: • Phone number signup • SMS verification • Optional email backup • PIN or Face ID login • Secure session management System must: • Prevent duplicate accounts • Securely encrypt user credentials ⸻ 2. Automatic Wallet Creation Upon signup, the...
I have two signed Android APKs that share the same brand: a Chinese-language build that already handles user registration smoothly, and an English-language build that currently lacks this flow. My goal is to extract every user-management API call from the Chinese APK—endpoints, headers, payload structures, encryption or signing logic—and transplant that functionality into the English APK so both variants register users in exactly the same way. What I can provide: • The release APKs for both language versions • Valid test accounts and server access for live registration checks • Any additional assets the Chinese build relies on (native libraries, certificates, config files) What I need from you: • Decompile, inspect and document the Chinese APK (jadx, a...
I need our web-based CRM, currently built in React, re-implemented as fully native apps for both iOS and Android. The existing REST and GraphQL endpoints are stable, so the job is mostly about translating interface logic and screens into Swift (or Objective-C) and Kotlin/Java while keeping parity with the browser version. Core functionality to reproduce • Secure user authentication with profile management • Full customer management workflow (create, edit, segment, assign, delete) • Analytics and reporting dashboards identical to the web charts and tables Design requirements The mobile UI must replicate the current design pixel for pixel. All colours, typography, spacing, and animations already exist in Figma; simply mirror them exactly so our users experience no ...
I need an experienced app developer to create a comprehensive online learning app for iOS, catering to 13 million learners. Key Requirements: - Primary function: Online learning - Must be compatible with iOS - Scalable architecture to support millions of users - User-friendly interface Ideal Skills: - Proven experience in developing large-scale educational apps - Strong portfolio showcasing similar past work - Expertise in iOS development and app architecture Please share your past work related to large-scale app development.
I want to ship a lean Android + iOS application that can 1) establish a Bluetooth Low Energy link to my peripheral and move data back and forth, and 2) instantly push out a user-defined BLE packet the moment the phone detects an incoming call. The BLE work is classic data-transfer: discover the device, pair, subscribe to characteristics, then read/write packets on demand. Stability in the background is critical; the link must stay alive (or reconnect quickly) when the screen is off. When a call arrives the app should listen to the system broadcast (Android) or CallKit/VoIP push workaround (iOS), pull the string the user previously defined, and write it over the existing BLE connection without visible delay. Please send a concise, detailed project proposal outlining: • your ...
I’m ready to commission an Android-only audiobook application and need an experienced mobile developer to take it from concept to Google Play release. At its heart, the app must stream and locally cache audiobooks, let listeners drop unlimited bookmarks while they listen, and handle one-tap downloads for fully offline playback. Monetisation is essential: new titles will be sold individually, so please wire the catalogue to Google Play Billing for in-app purchases. Authentication will be straightforward email-and-password login—either a lightweight back-end you spin up or a Firebase Auth integration works for me so long as it’s secure and quick for the user. Core flow I have in mind • Launch ➜ user signs up or logs in • Library screen lists available au...
I own a licensed copy of the Dooo Movie Streaming Android source code and now need it running live on Google Play. The current project refuses to compile because of dependency issues and an outdated SDK. Here’s what I need from you: • Open the project in Android Studio, upgrade it to the latest stable SDK/Gradle versions, and cleanly resolve every dependency conflict so the APK builds without warnings. • Configure package name, signing key, Firebase/Ad-mob (if present in the code), and any other runtime settings the template requires. • Run a full device/emulator test to confirm login, streaming, search, and push-notification flows all work exactly as in the template demo. • Generate release AAB/APK and guide me through—or directly handle—th...
I’m ready to move forward with a project that pairs a full-featured Android app with a matching website. The core requirement both share is secure, reliable user authentication—think sign-up, login, password reset, and the usual account-management flows. Everything else about the product’s purpose, design language, and long-term roadmap is still flexible, so I’d like to refine those details together once you’re on board. I don’t have a fixed technology stack in mind; whether you prefer Kotlin in Android Studio, Flutter, React Native, or another modern framework on the mobile side—and Django, Laravel, Node.js, or something cloud-native on the web side—I’m open to your recommendations. What matters most is clean architecture, maintainabl...
I need a straightforward mobile application that lets my team and I handle property inspections, repairs, and routine maintenance right from our phones on both iOS and Android. Each form should include Yes/No checkboxes, a comment area, and the option to attach photos so we can quickly document issues like a leaky faucet or damaged flooring. Real-time sync is essential: when one of us completes or edits a checklist, everyone else must see the update instantly. I’d like the data stored in the cloud—Firebase, AWS Amplify, or a similarly reliable backend—so nothing sits only on a single device. A second core feature is tenant-initiated work orders. Every unit should have a unique, scannable QR code. When tenants scan it, they’re taken to a simple screen (or a p...
Project Description I am seeking a high-level mobile app designer & developer (or a strong team) to build a multi-livestock management application inspired by the “Mqane” app, but with a much broader scope and stronger foundation. Mqane is limited to sheep only. This project must support multiple livestock types, selectable by the user (one or more). CRITICAL REQUIREMENT – READ BEFORE APPLYING Do NOT submit a proposal unless you have: Downloaded the Mqane app Tested it thoroughly Understood its structure, strengths, and limitations Any proposal that does not clearly confirm this will be ignored without review. Supported Livestock Types The application must support: Sheep Goats Camels Cows Horses Users may: Select one livestock type Or manage multiple types simul...
I already own a full, unmodified copy of the WoWonder PHP script plus the matching Android Timeline App (a release from within the past year). All I need is an expert who has done this exact job before to turn that code into a Play-Store-ready build. Here is what has to happen: 1. Connect the Android source to my live WoWonder PHP site, including any custom server tweaks the API needs. 2. Reskin: swap in the new app name, splash screen, logo (I will supply the artwork) and adjust the primary colours so the interface matches the brand. 3. Change the package name to a unique identifier. 4. Produce a signed APK and an AAB bundle I can upload straight to Google Play. 5. Send brief notes on anything I must replicate if I update the code later. The server runs a customised configurati...

I’m working with the AI-Powered Physiotherapy Recovery Flutter template from CodeCanyon (see link above) and now need a purpose-built backend to handle its scheduling flow. The mobile side is ready; what I’m missing is the server logic that lets therapists create, update, and cancel treatment sessions while automatically sending SMS reminders to patients ahead of each appointment. My priorities are clear: – Robust session scheduling and management endpoints that the existing Flutter code can call seamlessly (REST or GraphQL, your choice as long as it’s well-documented). – A background job or queue that fires SMS reminders at configurable intervals—Twilio, Nexmo, or another SMS gateway works for me provided it’s abstracted cleanly so I can swap p...

I want a single code-base app (React Native or Flutter is fine if it meets Apple and Google policies) that lets my users save any public video or audio they encounter online—Instagram Reels, YouTube clips, Facebook posts and beyond—directly to their device. The app must automatically detect the highest available quality, then offer MP4 for video and MP3 for audio before placing the file in a tidy, built-in library. The admin could see each user link they downloaded in a admin dashboard where he could see all people whom they are using the app. Core flow • Paste or share a link into the app • Choose format (MP4 or MP3) and resolution/bitrate • File downloads in the background, lands inside an in-app folder structure the user can rename, move or delete &bu...
Mobile Fuel Inventory & Blending App (Android + iOS, Multi-User) Project Description I am looking for an app developer to build a mobile-first inventory application for fuel trading and blending operations. The app will be used by drivers, supervisors, and the management team, so it must be simple, fast, and practical for daily use. 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 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 should be able to verify entries and manage site-level...
I’m ready to turn a productivity / utility concept into a polished mobile experience that runs smoothly on both iOS and Android. The end goal is a lean, intuitive app that helps users get things done quickly, whether they’re online or offline. Here’s what I need from you: • Full-cycle development – wireframes, UI design, coding, QA and deployment. • A single, shared codebase (Flutter, React Native or your preferred cross-platform stack) or two native builds if you can guarantee identical feature parity and performance. • Clean, well-documented source code that I can compile locally. • TestFlight / internal track builds for review, followed by successful submission to the App Store and Google Play.

I need an end-to-end delivery application that ships simultaneously on iOS and Android. The product will serve two audiences—customers who place and track orders, and couriers who accept jobs and update their status—so the UX must switch cleanly between those roles. Core features are non-negotiable: live GPS tracking that remains accurate to the meter, a secure in-app payment flow (card and wallet support preferred), and automated push notifications at every key milestone from pickup through drop-off. I’m comfortable with React Native, Flutter, or any other modern cross-platform stack as long as performance is smooth and native APIs for location, payments, and notifications are handled properly. Please structure the build so I receive: • Production-ready iOS and ...
I already have a finished Android application and the signed build is ready to ship. I need a reliable developer who can first walk it through a clean launch on Google Play—handling the Play Console setup, store listing, key management, policy checks, and final publication—then stay on as the point-person for routine maintenance. There are no new features or redesigns on the roadmap right now; the focus is strictly on stability. After release, I’ll rely on you to monitor crash reports, keep the SDK versions current when Google’s requirements change, and step in quickly if any compliance or compatibility issues crop up. Acceptance criteria • The app is live and searchable in Google Play with all assets, descriptions, and tags correctly configured. &bul...

This is not a complex app — but it must be polished, reliable, and built exactly to my requirements. What I Need Built: --Full Android app (React Native or native Android — open to your recommendation) --Backend/API setup (Node.js or Python preferred) --Clean UI/UX based on my wireframes --Basic database setup (Firebase, Supa base, or simil...
Hello, I need a custom mobile app that runs on Google Pixel 8 and newer. The app should open the Wire application, go through my entire contact list (500+ contacts), and send the same message to each person individually - no group chats should be created so that recipients remain anonymous to each other. Key features • Automatically navigate to each contact in Wire and send the message. • I select the text manually each time before sending starts. • Built-in log that records: – Message sent to each contact – Any error messages/problems – Exact time of each message sent • Runs entirely on the phone as a standalone Android app without requiring a computer or browser. • Ready to install via APK or Google Play (internal test channel is okay). Techn...
My Android app is fully built and live-tested; what I need now is a reliable developer who can take over the hosting and ongoing management so I can focus on feature ideas rather than infrastructure. Here’s the scope I have in mind: • Set up and configure a stable hosting environment suited to Android back-end services (Firebase, AWS, Google Cloud, or your preferred stack—as long as reliability, scaling, and basic security hardening are covered). • Handle versioned roll-outs and hot-fixes whenever I push new code, making sure updates reach the Play Store smoothly and any migration scripts run without downtime. • Proactively monitor performance, apply routine maintenance, and tune the back-end so the app stays fast and crash-free. all 3 apps are ready...
I’m ready to move my physical-goods store onto mobile and I need a developer who can deliver a polished, full-featured e-commerce app for both iOS and Android. Core buying flows must feel fast and familiar—browsing catalogues, adding items to a shopping cart, checking out through a secure payment gateway, and leaving product reviews once orders arrive. Beyond the standard shop functions, two extra capabilities are critical: • Quotation sharing – users should be able to receive quote inside the app, and forward or save it with a tap. I’m open to the framework you think best suits a dual-platform launch (React Native, Flutter, or native builds), as long as the result is smooth, scalable, and easy for me to update with new inventory down the line. Delive...
I need a full WhatsApp Business API workflow built for our coaching institute’s existing WhatsApp number. The goal is to handle common student queries instantly, guide them through tap-friendly menus, and feed every interaction into a live-updating Google Sheet that my team can monitor in real time. Core flow • When a prospect messages “Hi”, an automated greeting should fire and present three interactive buttons: Course Offerings, Admission Process, and Contact Support. • Tapping Course Offerings or Admission Process must trigger rich, structured replies with detailed course information; Contact Support should collect their name, phone, and the topic they wish to discuss, then forward it to a human agent. • All captured data—timestamp, phone ...
I am kicking off Phase 1 of the Expressions app exactly as defined in the signed Phase 1 SOW, Annex B, and Annex B-2. During this phase, the scope includes delivery of the complete server-side orchestration layer, system-level identity locking, and a deterministic AI execution pipeline, fully integrated into a native keyboard operating on both iOS and Android. The keyboard must: • Enforce the system-level identity lock, • Invoke backend AI execution to generate anchor- and burst-style emoji outputs, and • Surface generated results in real time within the keyboard experience. Authentication must rely on Sign in with Apple and Sign in with Google. The application must deny access, or selectively restrict features, when a user’s subscription status is not validated....
I need a very small Android application whose only job is to launch and immediately play a single MP4 video in full-screen. As soon as the user taps the app icon, the video should start on its own—no play, pause, seek bar, or any other controls visible. After the video finishes, the app can simply close or loop; I’m open to whichever is quickest to implement. The MP4 file will be provided. Please package it inside the APK, so the app works offline with no additional downloads. Android Studio, Kotlin or Java, and the built-in VideoView or ExoPlayer are all fine as long as start-to-finish playback is seamless on Android 8.0 and above. Deliverables: • Signed release APK for testing • Complete source code project that compiles in the latest stable Android Studio &bu...
My production Flutter app has begun to misbehave on Android 14, 15 and 16 preview builds. The root cause is obvious: the codebase is still on an older Flutter release and the underlying Android SDK has marched on. I need the entire project migrated to the latest stable Flutter version, compiled against the newest Android SDK, and thoroughly tested so it works smoothly on those three OS versions. The scope is simple but critical: upgrade the Flutter framework and all dependent packages, refactor any deprecated APIs, fix compile-time warnings, and resolve run-time crashes or layout glitches that appear only on the newer Android versions. Afterwards I expect a clean, reproducible build (Android App Bundle) plus a short changelog summarising what was updated and why. Deliverables • Up...
I need an Android social-networking app built from scratch. The core idea is a clean, modern platform where users can register, create profiles, add or follow friends, share text-photo-video posts in a scrolling feed, chat in real time, and receive push notifications. A lightweight admin panel for content moderation is also required. Please deliver: • Full Android Studio project (Kotlin preferred, Java acceptable) with well-commented source code • REST or Firebase backend setup, documented and ready for deployment • Brief UX prototype early in the process and a functional MVP roughly six weeks from kickoff • Clear installation guide and API documentation so I can extend or port it to iOS later Material Design guidelines should steer the UI. I’m happy to su...
I’m building a secure, full-featured e-commerce solution that runs smoothly on iOS, Android, and the Web. The core stack can lean on Python for the API layer, with Java or C++ wherever high-performance modules make sense, but I’m open to a workflow you can justify that keeps code clean, well-documented, and easy to maintain. Core scope The first release must cover user account management (registration, login, password reset, profile editing) and end-to-end payment processing with major gateways. A responsive storefront, basic product catalogue, and an admin dashboard will round out the MVP. UX consistency across mobile and web is essential, and I’d like to see thoughtful error handling, secure data storage, and unit tests from day one. Deliverables for this milestone ...
I already run a live, fully functional mobile web application built on the Lovable platform. It works well in the browser, yet I want to give users a true app-store experience—faster load times, smoother navigation, and the convenience of installing directly from Google Play and the Apple App Store. I’m open to either a pure native build or a modern hybrid solution; whichever approach you feel will deliver the best performance and maintainability is fine with me. What matters most is that the final apps feel truly native on both Android and iOS. One new capability must be added: push notifications. They need to work seamlessly on both platforms, using Firebase Cloud Messaging, APNs, or a comparable service that guarantees reliable delivery and easy future maintenance. You&...
I’m running an ongoing fraud-prevention test for RingApp and need help from people who are physically in Palestine, using an OOREDOO SIM on an Android phone. After installing the app, all you have to do is sign up with your OOREDOO number, open the profile screen, enable “Auto-perform tasks,” and leave the app active in the background. RingApp will trigger and instantly decline test calls on its own; you won’t have to answer or dial anything manually. Each block of 200 completed test calls releases a $5 milestone through Freelancer. The app tracks the call count for you, so payment is straightforward once the counter reaches 200 and the data syncs. Acceptance criteria • RingApp is installed and registered on an Android device with an OOREDOO SIM. • &...
I already have a fully-functioning web application and all the Play Store listing graphics (icons, feature graphics, screenshots, banners). What I need now is for someone to turn that site into an installable Android application and walk it all the way through publication on Google Play. The scope is straightforward: • Wrap or rebuild the existing web app into a compliant Android package (AAB preferred). • Configure signing, versioning, and any required permissions. • Create the store listing using the assets I will supply, fill out the content ratings and policy forms, and submit the release. • Hand back the final source, the signed AAB, and confirmation that the app has passed Google’s review or clear guidance on any requested fixes. If you have recent e...
I have an existing Android app that is stable but still very lean on features. The immediate goal is two-fold: first, roll out a new “upload” capability inside the app (users need to be able to select a file—primarily images or PDFs—from local storage and send it securely to our backend); second, compile, sign, and publish the updated build to the Google Play Console so the change is live for all users. The current stack is Kotlin with standard Android Jetpack libraries; the backend is ready and exposes a REST endpoint for the upload, so the mobile side only needs to handle file selection, progress indication, and a simple success/fail response. If you prefer Java that’s fine—as long as the final APK/AAB plays nicely with our existing codebase. Deliver...
I need an Android app that lets my field-marketing reps see their entire day laid out on Google Maps, record every turn they take, and automatically total the distance they cover. Each sales call is flagged as a Meeting Point marker so the team can tap it, log arrival and departure time, and have the visit counted in their daily report. Core flow • Reps start a “shift”, the app begins GPS tracking in the background and draws the live route on the map. • Every time they reach a preset Meeting Point, the app recognises the stop, time-stamps it, and asks for a quick note or photo. • When they end the shift, the app stores a summary: full polyline of the route, total distance travelled, list of visited Meeting Points, and idle time between stops. A simple d...
I’m bringing a brand-new casino-style dice experience—SnapCraps—to market, and I need a full mobile app to make it happen.
