I need a mobile application built specifically for Android that serves as a social-networking platform. The core idea is to let users create profiles, follow or connect with others, and share posts in a scrolling feed. Key needs • Clean onboarding with email or phone verification • Personal profile pages with photo, bio, and basic stats • Real-time feed where users can post text, images, or short videos • Like, comment, and share interactions • Push notifications for new follows, mentions, and comments • Secure back-end API and database setup (Firebase, Supabase, or similar) • Light, modern UI that follows current Android guidelines I’m looking for someone who can handle the full cycle—from setting up the database and API t...

I need a complete website built first, followed by a lightweight Android utility app that complements the site’s core features. The site will serve as the public-facing hub, while the app will handle on-the-go tasks that users might prefer outside a browser. For the website, bring responsive front-end skills and a solid back-end framework of your choice; speed, clean code, and scalability matter most to me. Once the site’s foundation is stable, we will move on to the Android build. The mobile component is a pure utility tool—simple, fast, and focused on one primary function—so lean architecture and a minimal footprint are key. Deliverables • Fully deployed, production-ready website with tested APIs • Android APK (and Play Console assets) wired to...

I’m ready to turn my existing Shopify store into a fully-featured mobile shopping experience. The goal is a smooth, native app for both iOS and Android that syncs seamlessly with my current catalog, inventory, and checkout flow on Shopify. Key functions I expect out of the box include real-time product sync, secure customer accounts, a streamlined cart and checkout, push notifications for promotions and order updates, and basic analytics. Design should stay on brand while still feeling app-native; if you have ideas to improve the UX without straying from Shopify’s guidelines, feel free to suggest them. Although I considered other platforms, I ultimately settled on Shopify because my store is already there, so deep integration with its APIs is essential. If you have completed ...

I’m ready to bring a brand-new social media experience to Android and need an experienced app developer who can guide the idea from concept to a polished release on Google Play. The core objective is straightforward: design and code an engaging, modern-looking Android application that lets users create profiles, follow one another, post updates (text, photos, or short videos), and interact through likes and comments. I have wireframe sketches that outline screen flow, but I’m counting on you for UI refinement, smooth navigation, and selecting the right tech stack—Kotlin or Java on Android Studio is fine as long as the final build is stable and future-proof. Robust back-end thinking is important too; whether you prefer Firebase, AWS Amplify, or another scalable service, p...

I need a fully functional mobile application that lets users place one-to-one video calls and get charged automatically by the minute. Both iOS and Android builds have to launch side-by-side, sharing a single codebase if possible so updates stay in sync. Core interaction is a real-time video call—WebRTC or an equivalent low-latency solution is fine as long as the quality holds on average networks. Around this, the app must also include lightweight in-app messaging for quick text exchanges, individual user profiles with avatars and short bios, and a seamless payment flow. Users top up a wallet or link a card, start a call, and the system deducts the correct amount every 60 seconds without gaps or rounding errors. I’m open to Stripe, Braintree, or another PCI-compliant gateway; ...

I’m building an Android and iOS app that lets students and teachers at my tuition centre talk to each other easily and securely. After a quick sign-up or sign-in, the app must recognise whether the user is a student or a teacher and show the right interface, so proper role-based authentication is non-negotiable. Core communication features I need in version 1: • Real-time messaging – one-to-one and class group chats with push notifications, read receipts and simple file sharing (PDFs, images, voice notes). • In-app video calls – smooth, low-latency sessions for remote doubt clearing, built with WebRTC, Agora, Twilio or a comparable SDK. • Subject-wise discussion forums – teachers start threads, students reply, everything neatly threaded for late...

I have a promising ball-pool title in the works and now need someone who is ready to own the Android build from here through launch and beyond. The core gameplay is already framed out, but I want a developer who can refine the physics, tighten performance, squash lingering bugs, and help me push a polished, commercial-grade release to Google Play. Key features on the roadmap are multiplayer mode, fully customizable tables and cues, and a robust in-game currency system. All art and effects must feel authentic—think clean, realistic tables, balls, and lighting rather than a cartoon look. To set us apart from the crowd we will layer in special power-ups and a couple of fresh game modes that aren’t found in the usual eight-ball experience, so comfort designing and balancing new me...

I’m looking for an Android developer who can build a lightweight calculator that handles the four basic operations—addition, subtraction, multiplication and division—and nothing more. The interface can be straightforward; it just needs to look clean on both phones and tablets and pass Play Console requirements without extra permissions. I will give you my AdMob App ID and individual Ad Unit IDs. Please wire them up so ads display properly in the released build and comply with Google policy. When you hand the project back, I need: • A signed, release-ready APK • The corresponding AAB file for Play Console • The complete, well-organised Android Studio source code Everything should compile out of the box and be ready for direct upload to Google Play. Le...

I want to build a polished mobile application that inspectors can use on-site, running smoothly on both iOS and Android from a single codebase. The heart of the product is fast, reliable photo capture: users must be able to shoot, review, annotate and attach media to each inspection point without ever leaving the app. Alongside that media workflow, the app should present ready-made inspection templates (civil, electrical, plumbing, etc.) while still letting the user design and save their own custom lists whenever they need something unique. A clean UI, offline operation with later sync, and one-tap PDF/HTML report export are important for day-to-day field work. Source code, build instructions and test builds for both platforms will be the final deliverables, ready for submission to the...

I’m building a fully-featured voice assistant that users can download on both iOS and Android. Think of it as a pocket-sized helper that can listen, understand, and act on spoken commands—setting reminders, fetching quick answers, controlling smart-home services via API, or triggering in-app actions. Here’s what I need from you: • A native or cross-platform mobile app (Swift/SwiftUI + Kotlin, or Flutter / React Native—whichever lets us land on both stores quickly and cleanly). • On-device and cloud speech recognition so the assistant responds within a second or two, even on slow connections. • Natural-language understanding: basic intent detection, entity extraction, and a fallback to a large-language-model endpoint when the user asks something ...

I have a brand-new mobile game that is ready for the world, but I need someone who knows the Google Play Console inside-out to take it from signed build to live listing and then keep it current. There is no existing store presence, so you will be starting from scratch: creating the listing, uploading the AAB/APK, configuring release tracks, setting up countries, pricing (free with in-app ads for now), and making sure the policy checks pass first time. Once the game is live, I want the same person to handle future updates—whether that means swapping in new screenshots, refining the description to improve ASO, or rolling out new versions through staged releases. Think of it as an end-to-end Play Store management role rather than a one-off upload. Key deliverables • Initial pub...

I need native smartphone users currently located in Belgium, Taiwan, Colombia, Argentina, France, Mexico, Chile, or Spain to run a round of functional tests on our dual-service mobile application. The job is straightforward: First, install the latest build on both iOS and Android devices you own. Create a new account so I can verify that user registration works smoothly in each market. Next, move on to the two core journeys—booking a ride and ordering food. Complete each flow from start to finish, including payment (we provide promo codes so you will not be out of pocket) and cancellation where relevant. While testing, note every screen, button, message, and edge case that behaves unexpectedly or feels confusing, capture screen recordings or screenshots, and collect basic device lo...

I’m looking for a developer who can build a production-ready Android application which is satta matka whose core function is a paid subscription system. The app will present users with two plan choices—weekly and monthly—and process every renewal through UPI, so the flow must be fully compliant with India’s recurring-payment guidelines. You’ll need to implement a clean onboarding screen that leads directly into the UPI checkout, enforce automatic access control based on the active plan, and surface a simple “Manage Subscription” area where users can upgrade, downgrade, or cancel at any time. Kotlin in Android Studio is preferred, but I’m open to Java if that speeds delivery and keeps the codebase maintainable. Please package the final APK...

I’m building a mobile-only marketplace that lets independent gyms list their facilities while giving users a single place to discover nearby gyms, book sessions, check in, and track their visits. Every user will authenticate with a mobile number and one-time password; no emails or social logins are required. Core user flow • Browse gyms on a location-aware map or list • Reserve a workout slot and pay in-app • Receive an automatically generated QR code for entry • Scan the code at the gym to register the visit, which updates the personal visit log in real time Gym partner flow • Register the gym, set schedules and capacity limits directly in the app • Scan incoming QR codes at the front desk to confirm attendance • View automated ...

My mobile application for the general public is already coded for both iOS and Android, but it still needs a final push before launch. I’m looking for someone who can take full ownership of the finishing phase: hunt down and fix every bug, wire up eight payment gateways alongside two payout methods, connect the existing P2P + SFU server, move the backend to its new hosting environment, document the whole process, and finally publish stable builds to the App Store and Google Play. Deliverables • End-to-end functional and regression testing with issue resolution • Seamless integration of 8 payment gateways and 2 payout flows already selected in the codebase • Configuration of P2P and SFU services inside the app so real-time features perform smoothly under load &...

I have an Android app that displays a scrolling list of short text clips. I now need a quick-pin workflow: • When the user single-taps a clip, it should toggle into a “pinned” state and remain visible indefinitely. • Any clip that is not pinned must be automatically removed exactly one hour after it is created (or last edited), even if the app is closed in the meantime. • Visual feedback is important: pinned items should be clearly distinguishable from regular ones (icon, color badge—your call, as long as it follows Material guidelines). You are free to work in Kotlin or Java and may choose the persistence layer that best fits—Room, DataStore, or another solution—so long as the auto-deletion runs reliably in the background (WorkManager or ...

I’m ready to turn a solid game concept into a polished mobile title that runs exclusively on Android phones and tablets. To make that happen, I need an experienced Android game developer who can take the idea from paper to a release-ready build. Scope of work • Design and implement core gameplay mechanics, UI, and animations • Optimise performance across the current Android OS range • Integrate ads, in-app purchases, leaderboards, and basic analytics • Produce a signed, release-ready APK with complete, well-commented source code Preferred toolset Unity with C# would be ideal because my early prototypes live there, but I’m open to a native Android Studio (Java/Kotlin) approach if you can justify the benefits. Acceptance criteria • Smooth, ...

I’m ready to bring a full-featured, Uber-style taxi service to life and need a developer (or small team) who can take the project from concept to launch on both iOS and Android. The passenger app must include frictionless user registration and secure login, real-time ride booking with live vehicle tracking on a map, plus in-app payment integration that supports major cards and digital wallets. In parallel, I also require a separate driver app. It should mirror the passenger experience where appropriate, receiving ride requests, turn-by-turn navigation, earnings summaries, and status toggles, while keeping the codebase as maintainable as possible. Key expectations • Native or cross-platform code that meets Apple App Store and Google Play guidelines • Clean, well-docume...

I need an experienced Android team to build two separate Play-Store-ready apps, starting with the Medicine Selling App. The ride-hailing platform will follow once the pharmacy solution is live. Medicine Selling App – phase one The core experience is a clean, secure mobile storefront where customers log in with phone-number verification, search medicines by name, browse existing product categories, upload a prescription when required, add items to cart, pay in-app, and track delivery in real time. An internal courier module should let my dispatchers assign, monitor and update order status from preparation through doorstep drop-off. Rider Booking App – phase two After the pharmacy app is published, I’ll move straight to the Uber-style solution: passenger and driver si...

I need an Xposed module that tightens security by controlling app permissions automatically, based on user-defined conditions rather than simple allow/deny prompts. The idea is to intercept any permission request at runtime, check it against a rule set (time, network, app state, or other triggers we agree on), and then grant, deny, or prompt accordingly— all without touching the original ROM. Scope – Develop the full module in Java/Kotlin for the current Xposed/EdXposed framework. – Build a compact UI for adding, editing, and importing rule profiles so users can craft conditions such as “Block camera when screen is casting” or “Allow location only on trusted Wi-Fi.” – Ensure rules apply instantly after creation and survive reboots. &nd...

I need a complete Android Enterprise Mobility Management system built from the ground up, focused squarely on device management. The platform must let me enrol, configure and oversee fleets of smartphones and tablets through a web console and accompanying Android agent. Core scope • Robust enrolment workflows (QR code, zero-touch and manual) that place devices in Device Owner mode. • Policy and configuration push—Wi-Fi, apps, restrictions—applied instantly or on schedule. • Live dashboard showing device status, compliance flags and basic audit logs. • Remote actions (lock, wipe, reboot) executed securely over the air. • Scalable back-end with REST APIs so we can integrate ticketing and reporting later. Tech expectations – Android Ent...

I'm looking for immediate support to resolve the "Error 3 - Code Already Used" I receive when attempting to upload an AAB package to the Google Play Console. Current Situation • The app compiles and launches successfully locally. • When uploading the AAB release, the console blocks the publication, reporting Error 3 with the message "Code Already Used." What I Need 1. Quick analysis of the Gradle project to identify the cause (versionCode/versionName, signature, automatic increments, any pending artifacts). 2. Correction of the offending parameters and generation of a new signed AAB. 3. Successful upload of the release to the Google Play Console with my confirmation. I will accept the job when: • The corrected AAB is accepted without errors by the...

I want to launch a streamlined e-commerce app built specifically for Android. The goal is a fast, intuitive shopping experience that lets users browse products, manage a cart, pay securely, and track their orders—all from their phones. Key requirements • Native or high-performance cross-platform build for Android only. • Clean, modern UI that follows Material Design. • Secure user sign-up/login, profile management, and password recovery. • Product catalogue with search, filtering, and detailed views. • Shopping cart, checkout flow, and payment-gateway integration. • Order history and basic order-tracking screen. • Simple admin connection or API hooks so I can update products, prices, and inventory without republishing the app. Ni...

I’m ready to turn a simple concept into a polished mobile app that runs smoothly on both iOS and Android. At this stage the core requirement is straightforward: users must be able to create an account, sign in, and stay securely authenticated throughout a session. I’m open to the framework or language you prefer—whether you lean toward Flutter, React Native, Kotlin Multiplatform, or native Swift UI and Kotlin—as long as the final build is stable, fast, and easy to maintain. Here’s what I need from you: • A complete cross-platform codebase with clean architecture and clear documentation • A lightweight, modern UI that looks native on each platform • Secure user registration, login, and persistent authentication (email/password at minimum; ...

I need a lightweight Android application that lets Homzo customers book essential home services—water-tank cleaning, AC maintenance, plumbing, electrical work and similar jobs—and then connects those requests to our on-field technicians through a dedicated technician interface, all managed from a small admin panel. Core flow • Customers sign up or log in with a phone-number-based OTP gateway and immediately see a list of service categories. After choosing one, they confirm address and contact details, send the request, and can watch its status change in real time. • Technicians sign in, review jobs assigned to them, accept or reject with a tap, mark work complete and upload a photo as proof of completion. • In the admin panel I must be able to add or deact...

I already have the iOS and Android build folders packaged, certificates generated, and step-by-step documentation prepared. All that’s left is the actual submission to Apple App Store and Google Play Console. Here’s what I need you to do the moment you receive the files and credentials: • Log in to both developer consoles, follow the supplied documentation, and upload the binaries, screenshots, descriptions, and icons exactly as provided. • Configure the necessary store listings (privacy policy links, age rating, pricing set to free) without altering any content. • Initiate review on both stores and send me the submission receipts or screenshots showing the apps “Waiting for Review”. Everything is ready for a straight upload, so this is a...

I want a single, integrated system that lets my staff manage two key tasks with ease: collecting student fees and handling new admissions. The solution has to include a responsive web interface for administrators and an Android app for parents and students. On the admission side, applicants must be able to fill out an online form and upload the required documents directly from their phones or any browser. All submissions should sync to a central database so my team can review them in real time and export the data whenever needed. For fees, the priority is an automated reminder engine that can send scheduled push notifications and emails ahead of due dates, at custom intervals we define. Although I am open to adding payment gateways or history tracking later, this first release only needs...

I’m building a mobile video application inspired by So Live and need it released on both iOS and Android. The heart of the product is real-time live streaming where viewers can interact with hosts, create and update their own profiles, and spend or earn virtual coins. Coins must work in two ways: users can buy pre-defined bundles through in-app purchases or accumulate them through in-app activities and rewards. Package sizes and pricing tiers will differ from the reference app, so the bundles and their validity periods need to be completely configurable from an admin view or a simple JSON file you set up. Key elements to deliver • Native or cross-platform code that compiles cleanly for App Store and Google Play. • Low-latency live video streaming with chat and basic m...

I need a cloud-connected Android application that lets me handle GST billing from end to end. The core workflow must cover invoice generation, accurate tax calculation and a simple client database, all stored securely in the cloud so data stays synced across devices. Beyond those basics, I also rely on: • Inventory management tied directly to sales and purchase entries • A built-in payment gateway so customers can settle invoices instantly • Clear reporting and analytics dashboards (sales, tax collected, stock levels, etc.) • Ready-to-export GST filing formats to speed up my monthly returns The interface should be clean and fast, working smoothly on current Android versions. I will need full source code, deployment to the Play Console, and a short hand-off ses...

I am preparing a Kickstarter campaign and need a clear, professional estimate for building a very focused photo-sharing application. The core idea is simple: each user may only upload images and view their own gallery—no public feeds, comments, or social discovery. I would like users to be able to label the photos they upload if they choose to create an account. Scope and key requirements • Native support for both iOS and Android. • Users reach the upload screen by scanning a QR code; from there they can either continue anonymously or create a basic account (email or phone-based). • Photo upload must work from the device gallery and directly from the camera. • Server side should store each user’s images in an isolated bucket so no cross-access is...

I have a Mediatek 8168-based tablet (board ID tb8168p1_bsp, retail model Score 7T). I can put the device into BROM mode with mtkclient and it identifies as “SBC enabled = true”. What I need now is a fully working Android build custom-tailored for this hardware and a reliable procedure to get it flashed onto the tablet. The goal is a clean, stable Android ROM—version is flexible, so feel free to recommend the best fit for MTK 8168 in terms of driver support and security updates. I do not yet have a suitable ROM image, so I’m looking for someone who can build or port one from source (AOSP or other open-source base) and walk me through flashing it. Key deliverables • Bootable Android system image (system, vendor, boot, dtbo, vbmeta, etc.) compatible with tb816...

I need a dedicated software developer to build a polished Android mobile application from the ground up. I already have the core concept and basic feature list sketched out; what I’m missing is an expert who can translate that vision into clean, efficient Kotlin / Java code, craft an intuitive Material-compliant UI, and guide the app right through to a signed Play-Store-ready build. Here’s what success looks like to me: • A fully functional Android app that runs smoothly on current OS versions and common screen sizes. • Well-structured source code pushed to a private Git repository with clear commit history and inline comments. • Lightweight technical documentation (set-up steps, build instructions, and an API overview if external services are used). &bu...

IMPORTANT UPDATE – READ CAREFULLY This is NOT a design contest. This project was mistakenly posted as a contest. It is actually a highly technical Android development task. Only serious Android developers with experience in LSPosed, Zygisk, Magisk modules and Camera2 internals should participate. Generic diagrams, flowcharts, AI-generated explanations or conceptual images will NOT be considered valid submissions. Technical Objective Device: Pixel 8a (akita) ROM: EvolutionX 15 (Android 15) Root: Magisk + Zygisk + LSPosed Goal: Force a USB UVC external camera to behave as the ONLY usable system camera. Requirements: Any app requesting a camera must open ONLY the external USB UVC camera. Internal physical cameras must be unusable or invisible. No ROM building. No vendor mod...

I’m building an Android-based equalizer app whose very first mission is solid, low-level I2C communication. The app must be able to discover and talk to an external audio-amplifier chip on the bus, read and write its registers in real time, and let a physical remote-control key trigger those same EQ changes inside the UI. I2S handling can follow later, but rock-steady I2C comes first. You may choose any practical route—GPIO lines available on an Android SBC, a USB-to-I2C bridge, or another proven method—so long as it runs on a stock Android build. I can supply the amplifier’s data-sheet and register map as soon as the project starts. Deliverables • Full Android Studio project (Kotlin or Java) with clean, well-commented source • Working APK that finds...

I already have a fully-built Android application and the complete source code is ready for you in Android Studio. Before I take it live again, I need a short round of polish: • Triage and resolve a handful of bugs that surfaced during my own testing. • Tweak or optimise existing features—nothing brand-new, just making what is already there work more smoothly and reliably. Once those fixes are in place, I also need hands-on help getting the app through the Google Play Console, including preparing the release build (AAB), completing the store listing assets, handling policy checks and guiding it all the way to an approved rollout. Please be comfortable with Play Console best practices, policy compliance and the most common rejection traps so that the submission sails...

I need a straightforward engineering services booking app that runs on iOS and Android. The whole experience should feel as familiar as any on-demand platform: a user opens the app, browses available engineering specialties, picks the service, chooses a time slot, and confirms the request. The single must-have feature is a smooth Service booking flow. Project tracking, consultation scheduling, and even a future Web version remain optional for later phases, so a modular architecture that leaves the door open for them would be ideal. Whether you prefer native Swift + Kotlin or a high-quality cross-platform toolkit such as Flutter or React Native is fine with me, provided performance and UI polish stay first-class. A cloud back end—Firebase, AWS Amplify, or something comparable—...

I need a streamlined Android mobile application whose core function is a clear, intuitive snack-selection menu. The flow is simple: users open the app, browse categories or search directly, tap an item, and add it to a lightweight cart. At this stage I am not including in-app payments or review screens, so your effort can stay focused on perfecting the menu experience, item imagery, and quick navigation. Key points to cover • Native Android build (Kotlin or Java—whichever you are faster with) • Simple, modern UI that fits Material 3 guidelines • Category filter, search bar, and product detail pop-ups with image, price, and short description • Local data storage or a small Firebase/SQLite back-end so items can be updated without a new APK push • Cle...

My Android app is ready to go—code signed, fully tested, and sitting in its final AAB build. I already have a verified Google Play Console account; what I need now is a smooth, error-free deployment. Here’s the scope: • Create the production release in Play Console, upload the AAB, set up the release notes, and handle any bundle optimiser warnings. • Populate the store listing with the assets I provide (screenshots, icon, short and full descriptions, privacy policy URL). • Configure pricing, countries, content rating, Data safety form, and all policy declarations so the submission is 100 % compliant. • Walk me through the review and rollout steps so I understand how to push future updates myself. A successful hand-off means the app is live (or at l...

I need a mobile application whose sole focus is deepening the relationship I have with my customers. The core of the project is a fully featured loyalty program that lets users collect points and redeem rewards on every visit or purchase. To keep the conversation alive, the app must deliver timely push notifications—targeted offers, new-flavour announcements, and reminders—so customers always know what is fresh and available. Inside the storefront section, shoppers should be able to browse our full list of flavours, add items to a cart, place an order, and then follow that order with real-time tracking until pickup or delivery is complete. Key deliverables • Loyalty program engine (points, tiers, rewards) • Push-notification system with easy message schedul...
