    I want a full-featured Texas Hold’em poker game for Android that captures the fast, social feel of Zynga Poker. The scope covers everything from the core game engine to the live multiplayer backend, so the finished APK can be published straight to Google Play. The gameplay must support real-time tables, smart matchmaking, in-game currency, and an intuitive lobby.

    I need a lightweight Android application that keeps my customers instantly informed about their purchase progress. The core task is to build a stable push-notification system that fires whenever an order moves to a new status in our back-end. Each notification must be clear, timely, and triggered exactly once per status change so users never miss an update or receive duplicates. My API team will expose a simple REST endpoint returning the current order state; you can poll it or use webhooks—whichever gives the most reliable result on Android. Feel free to integrate Firebase Cloud Messaging if it speeds things up; I just need the service to scale and to handle basic fail-over scenarios. At this stage I am not asking for full real-time map tracking or a user-login module, but I would...

    I need an Android application that allows people to join real-time voice chat rooms, exchange short voice messages, and build public or private groups around shared interests.

    I need a complete Android application that lets both riders and drivers schedule rides ahead of time. The scheduling flow is the highest priority: a rider should be able to choose pickup, destination, date, and time; a nearby driver receives the request, can accept or decline, and both parties get confirmation inside the app. Although real-time tracking and payment integration are off the critical path for this first version, the codebase should be clean and modular so those features can be bolted on later—or even ported to iOS or Web without a full rewrite.

    I have a fully-built mobile app in FlutterFlow that I’m now ready to take native. Your job is to reproduce the entire experience in Swift for iOS and Java for Android, matching the original design pixel-for-pixel, duplicating every feature, and retaining the same smooth performance—or improving it where possible. The current build works, but being tied to FlutterFlow limits my control over custom code and optimisation. I’ll provide the existing FlutterFlow project, Figma screens, backend endpoints, and a brief test plan so you can see what “identical” really means. Key expectations • UI/Design fidelity: layouts, colours, typography, animations, and any custom widgets must look and feel exactly the same on both native platforms. • Features &...

    We operate as a software house and are delivering this project for one of our clients.

For this reason, we are looking for an individual developer or a team with whom we can establish long-term cooperation.

    I want to bring a straightforward ride-booking idea to life: users open the app, set pickup and drop-off points, and instantly secure an individual ride. Nothing fancy like car-pooling or luxury tiers—just reliable, on-demand transportation. I will launch on both iOS and Android at the same time, so a single codebase (Flutter, React Native, or similar) is preferred, though I’m open to fully native builds if you can justify the benefit. The flow should feel as frictionless as the big names: live map, real-time ETA, fare estimate before confirmation, in-app wallet or card payment, and a clean trip history. A lightweight driver interface and a small web-based admin dashboard will round out the ecosystem so I can manage drivers, rides, and payouts without extra tools. Deliverable...

    I want to turn a single Android phone into a 24-hour ad-viewing machine that can reliably play through roughly 1,000 video ads every day and credit each completed view to my account so the revenue comes straight to me. Your job is to build the full workflow—from launching the ad source, through watching the videos in the foreground or background, to confirming each view and moving on to the next one without manual taps. Key needs • 100 % Android-only solution (no Windows, macOS, or Linux tools in the loop). • Works on a standard, non-rooted smartphone running the latest public Android release. • Handles the entire cycle automatically: open ad, let it run to completion, wait for the “Close” or “Next” prompt, then continue. • Stays u...

    I’m preparing a round of deep-level AOSP changes and need an architect who already feels at home inside the framework layer. The focal point is refactoring Activity Manager Service, Window Manager Service and Package Manager Service so that new behaviour in System UI, the Launcher and the Android permissions/security model can sit cleanly on top. Your job is to help me translate a high-level product vision into concrete, review-ready patches and documentation. That means exploring design options, defining the right hooks in System UI, shaping launcher flow changes, and hardening or relaxing specific permission paths without breaking CTS. Please attach a detailed project proposal explaining: • how you would structure the AMS/WMS/PMS modifications • the strategy you use ...

    I’m building an Android-only application that mirrors TikTok’s in-app coin recharge experience. The flow should feel instantly familiar to users yet remain fully compliant with Google Play policies and any payment-provider requirements. Core functionality • Secure user authentication so each balance is tied to a verified account. • Seamless payment-gateway integration (any widely supported Android SDK is fine) with proper handling of purchase confirmations, failures, and refunds. • A clear transaction history screen that logs amount, date, status, and reference ID. Design direction The interface must stay simple and minimalistic—clean typography, plenty of white space, and intuitive navigation similar to native Material-You guidelines. What I wil...

    I have a fully-built React Native application that offers random chat and call functionality. It already runs on test devices; I now need a developer to give it a clean bill of health and push it live on Android. Here is what I expect: • Audit the existing codebase and run the app end-to-end to confirm everything behaves as intended. • Fix any minor glitches you spot during that audit—nothing major is anticipated, but I want no surprises once users come aboard. • Connect the app to our server and make sure real-time chat and call features stay stable under live traffic. • Prepare, sign, and publish the release build to the Google Play Console, completing all store-listing steps until the app is publicly available. Once this pilot proves solid, I’ll h...

    I am looking for a seasoned software engineer who can take a utility-focused mobile application from concept to launch on both iOS and Android. The core idea is a practical day-to-day tool, so usability, small footprint, and smooth performance matter more to me than flashy visuals. What I need from you: • A native-quality experience on both platforms—feel free to use Swift/SwiftUI, Kotlin, Flutter, React Native, or another approach you trust, as long as the end result is indistinguishable from a fully native build. • Clean, well-documented source code handed over through Git. • Thorough in-app testing, followed by TestFlight / Google Play internal testing, with any critical issues resolved before public release. • Store-ready builds and a short hand-off gui...

    I need a small utility that automatically presses the “Skip,” “Close,” or “X” button whenever a video ad appears on an Android device. The focus is strictly on video ads for now, but I’d like the underlying logic to be flexible enough to extend to other ad types down the road. Platform • The first release must work reliably on Android. If it also happens to skip any other app ads without extra effort, that’s a bonus, but Android-wide coverage is the priority. Ad-detection approach I’m open to whatever technique you believe will be the most accurate and light on resources—image recognition, pattern recognition, accessibility-service hooks, or a smart hybrid. Explain briefly in your proposal why your chosen method is the ...

    I need an Android-only application that mirrors the core functionality of MobileRecorder24 while adding a fully integrated key-logging module. The build must capture the screen and system audio in the background and log every keystroke, saving all three data streams locally with the option to auto-upload to a URL I will supply later. Because I want the app to stay light, the interface should be simple and minimalistic—just a clean dashboard that lets me start or stop recording, browse stored files, configure upload credentials, and view basic status indicators. No extra visual clutter, no unnecessary animations. Your work should result in: • A signed, install-ready APK that runs smoothly from Android 8 onward • Well-commented source code (Java or Kotlin) so I can ...
