I’m building a brand-new mobile application that must launch on both Android and iOS. The concept, wireframes, and design assets are ready; now I need the complete app coded, tested, and prepared for store submission. Scope of work • Plan the architecture, choose an appropriate tech stack (native Kotlin + Swift or a cross-platform solution such as Flutter or React Native), and set up the project repo. • Integrate the backend REST APIs I provide, handle secure authentication, real-time push notifications, and any additional modules defined in the product backlog. • Implement analytics, automated tests, and a simple CI/CD pipeline so each milestone produces a store-ready build. Deliverables 1. Clean, well-documented source code for both platforms. 2. Play S...

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 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.

I’m launching my own cryptocurrency and now need a fully-functional software wallet that runs smoothly on both iOS and Android. The app must let users create or import a wallet, generate a secure mnemonic, view real-time balances, and send or receive funds with QR-code convenience. All signing happens client-side; private keys stay encrypted on the device and can be unlocked with PIN, Face ID, or fingerprint. You’ll integrate directly with the coin’s daemon or a lightweight JSON-RPC/REST gateway that I’ll expose, handling key derivation, transaction building, and broadcast. A clean, intuitive UI is essential so first-time users feel at home. React Native, Flutter, Kotlin/Swift—any modern mobile stack is fine as long as the final binaries satisfy App Store and...

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 need a full-stack developer who can turn my concept for a secure audio- and video-calling service into a polished, production-ready app on both Android and iOS. The core experience must feel crystal-clear on every call, so please lean on WebRTC (or a comparable engine) to guarantee high-definition quality even on moderate bandwidth. Security sits above everything else: all voice, video and chat traffic has to be end-to-end encrypted, and every new session must be protected by two-factor authentication. I am open to Google Authenticator, SMS or push-based 2FA—whichever integrates cleanly with the chosen backend. A built-in coin system will power monetisation. Users should be able to: • top up coins through standard in-app purchase APIs, • spend coins per minute of ca...

I’m developing a fully native Learning Management System for both iOS (Swift) and Android (Kotlin). The product must seamlessly serve multiple schools or training organizations from the same code-base while keeping each tenant’s data and branding isolated.

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...

Six years ago I released a small Android billing application; today all I have left is the signed APK. The original source code is gone, so I need a developer who can either clean-decompile the APK or, if that proves impractical, rebuild the project from scratch in the latest Android Studio while matching the existing workflow. Core workflow to preserve – billing and invoicing, – customer management, and – reporting and analytics. On top of that I want to add inventory management and a secure user-authentication layer. I have not fixed a login method yet, so you are free to recommend email/password, biometric, social sign-in or any modern alternative that fits the current Google Play guidelines. I will provide the live APK and a short screen-capture showing how...

I need a small, self-contained service that can ask Google Play Integrity for a fresh device token whenever my backend requests one. The scope is Android only; no iOS or web considerations are required right now. A simple HTTP/JSON API will be the front door—my server posts a device identifier (or any data you recommend) and your service replies with the newly issued integrity token. Key expectations • You wire up the official Play Integrity API, handle authentication with Google, and return the token in a secure, well-formed JSON response. • The endpoint must scale for burst traffic but a single-instance Docker image is fine to start. • Clear README covering setup, required Google Cloud credentials, and a short curl example are part of the delivery. • Any ...

I need an experienced Android developer to turn my concept for a Utility/Tools application into a polished, ready-to-publish APK. What I’m after • A clean, well-structured Android codebase written in Kotlin or Java. • An intuitive UI that follows current Material Design guidelines. • Core utility features implemented exactly to spec (I will share wireframes and user stories once we start). • Basic analytics, crash reporting, and in-app update handling. • Clear build instructions so I can compile the project locally. I’ll handle all artwork and copy; I just need you to integrate the assets and ensure everything runs smoothly on recent Android versions. Regular progress updates through Git or a similar repo are important to me, and I’d...

I want to launch an Android-only mobile application whose core purpose is blogging so I can share lessons and insights from my online classes with students. The must-have capabilities for this first release are a smooth post-publishing workflow (text, images, short videos) and built-in shareability that lets readers pass any article straight to their social-media apps with a single tap. You are free to choose the tech stack—Kotlin, Flutter, React Native, or any modern Android-friendly framework—as long as the final APK is stable on current versions of Android and the codebase is clean and well-documented. A lightweight backend or Firebase setup for storing posts is fine; I simply need to create, edit, and delete articles from an admin side and have them display instantly for...

I need a complete Android application that functions as a social-media platform. From the first install the user should be able to register, create a profile, post text, images or short video, follow other users, and interact via likes, comments and private messages. A clean, intuitive material-design interface is essential because this is the main space where people will engage every day. The core back-end services—authentication, real-time feed, media storage and push notifications—can run on Firebase or another cloud stack you’re comfortable with, provided it scales easily. Please integrate standard privacy tools (blocking, reporting, content moderation hooks) so the app is ready for public release. Deliverables • Production-ready Android Studio project with wel...

I will give you a working Android application that I own the rights to and need it rebuilt from the ground up. All screens, flows, wording, colours, animations and behind-the-scenes logic must match the reference exactly, so a user moving between the two apps notices no difference. You are free to use Kotlin or Java in Android Studio as long as the finished code is clean, well-commented and ready for future updates. If the original app relies on a simple server or local database, mirror that structure; if it calls external APIs, point the new build to the same endpoints. I will supply any keys or assets you need. Deliverables • Complete Android Studio project with source code • Release-ready APK (and, if possible, an App Bundle) • Brief build/run instructions so I can ...

I want to turn my idea for a social-media-focused Android application into a working product. The core concept is a modern platform where users can create profiles, share posts, interact through comments or reactions, and receive real-time updates via push notifications. I already know this will be Android-only for now, so every design, interaction, and line of code should feel native to current Android UX patterns (Material 3, latest Jetpack libraries, Kotlin preferred). Here is what I need from you: • A complete, well-structured Android project with clean architecture that I can open in Android Studio. • A functional APK for hands-on testing, plus release-ready build settings. • Source code fully commented in English and delivered through a private Git repository. ...

I need a clean, lightweight Android utility focused purely on file management—specifically, moving files from one device to another. Think of it as a straightforward “send-receive” tool that a user can open, pick any file on local storage, and push it to another phone or tablet without fuss. Core requirements • It must excel at file transfer between devices. I’m open to the underlying transport method—Bluetooth, Wi-Fi Direct, nearby-share style over local network, or a combination—so long as transfers are reliable and fast. • The interface should follow current Material guidelines so the listing looks polished on Google Play. • No cloud backup, compression, or other extras are needed at this stage; keeping the scope tight is a prior...

I am preparing to launch a local food-delivery service in Sivakasi, Tamil Nadu and need a full, ready-to-deploy software package.

I need an Android-only e-commerce application whose first release concentrates on a smooth shopping-cart flow and a secure, hassle-free checkout. Think of it as the purchasing core of a larger store: products are already stored in a backend API I provide, so your mission is to turn browsing items into confirmed orders with as few taps as possible. Key requirements • Kotlin (preferred) or Java inside Android Studio • Add-to-cart, quantity edits, promo-code handling, and real-time basket total updates • Multiple payment gateways (Stripe is mandatory; PayPal is a nice-to-have) with tokenised, PCI-compliant processing • Order confirmation screen + push/email receipt trigger • Clean MVVM architecture, Retrofit for API calls, and Firebase Crashlytics for basic...

We need an Android developer to add iPhone-style panorama to the Open Camera app (open source: ). Goal: Implement panorama in Open Camera so it works like iPhone: guided on-screen motion, smooth horizontal panning, and one stitched panorama image. • Works seamlessly on both the front and back cameras. • Guides the user with the same arrow-line UI Apple uses, keeping motion smooth and level. • Captures a continuous series of frames, stitches them on-device, and outputs one high-quality image without pushing memory limits. You’ll work only against the official Open Camera codebase (or a clean fork you create). I’ll take your branch and merge it into our own app later.
