I already have full, working source code for an e-commerce application on both Android and iOS. No new features are required right now—I just need clean, release-ready builds. You will receive the entire project, including all assets and any existing keystore, provisioning profile, or certificate information I have. Your task is to open the projects in Android Studio and Xcode (or the appropriate IDEs), resolve any dependency issues, and generate production builds. Deliverables • Android: signed APK or AAB, ready for Google Play submission • iOS: signed IPA, ready for App Store Connect upload Once the builds install and launch successfully on real devices, the job is done.
I want to launch a non-custodial crypto wallet that covers the essentials from day one. Users must be able to send and receive coins or tokens, browse a complete transaction history, and restore access at any time through a secure backup flow (seed phrase or encrypted file). The first release targets Android and a browser-based version. Feel free to use Kotlin, Flutter, React Native, or similar for mobile, and React/ (or comparable) for the web client, so long as the codebase is clean and well-documented. Security should follow a solid “standard” approach: client-side key generation, AES-256 encrypted private keys, optional PIN/biometric unlock, HTTPS everywhere, and no server-side custody. Compliance with common audits or libraries (e.g., WalletConnect, ) is welcome but not...
We operate a residue recovery business across 12 different locations. At each location, labour manually cleans and collects residue in sacks or load direclty in trolleys.

My Android app is finished and I’m ready to see it live on the Google Play Store. I need someone who can take the build I provide (AAB or APK), walk it through every Play Console step, and make sure the first production release is approved without hiccups. What I will hand over: the signed build, app icon, screenshots, description text, privacy-policy link, and any other assets you need. What I expect back: • A properly configured Play Console listing with all metadata completed • Correct bundle signing, versioning, and compliance checks (target SDK, 64-bit, Data Safety, etc.) • Internal test track upload to confirm install, followed by staged rollout to production • Clear notes so I can repeat the process for future updates If you notice anything tha...
I’m building a full-stack, fully secure money-exchange platform that spans Android, iOS, and a responsive website. The public landing screen must fetch and display up-to-the-second buy/sell rates even for guests, then invite them to sign in. Authentication will rely on Google Authenticator one-time codes; every sensitive endpoint must be locked behind this 2-factor flow. Once inside, customers need a clean dashboard where they can: • place buy orders • place sell orders • review a complete, filterable transaction history Behind the scenes I’ll need an admin console that lets me adjust spreads manually or, at the flip of a switch, pull live forex data from an API (feel free to recommend the most cost-effective feed). All price changes should propagate ...

I need a React Native specialist to build a full-featured grocery e-commerce application that runs smoothly on both iOS and Android. The core idea is straightforward: customers should be able to browse a fresh-produce catalog, add items to a cart, and complete checkout without friction. Here is what matters most to me: • A clean, searchable product catalogue optimised for frequent updates and large inventories. • A reliable shopping-cart flow that keeps state even if the user momentarily leaves the app. • Fast, secure payment-gateway integration so buyers can pay with cards or popular wallets. • Solid performance on mid-range devices and an intuitive UI that looks native on each platform.

Need a mobile application which can be installed either Apple or android. The app must be able to use over web based environment (later onwards) you must think whether the app can be transformed into webspace later without an additional cost before you start. The app is all about managing activities related to tea green leaf buying and selling them to tea factories. App user is a dealer who buy green tea leaf from small holders and then supply the leaf to factories. He is doing an intermediate business. The dealer daily collets leaf. While collection they usually write the gross weight of green leaf and then deduct some weights according to leaf condition. Then they transfer leaf to factories by their Lorries and same kind of weighing happening at the factory gate. Dealer should be a...
I’m building a full-featured astrology site that does more than generate charts—it will actively guide astrologer through the ups and downs of planetary transits, mahadasha and antardasha phases. So that Astrologer can notify their client on good and bad transits, good and bad mahadasha, antardasha insights also provide insight into challenging and favorable time and then rely on an intelligent alert engine to tip them off before key moments arrive. Core scope • Planetary transit insights presented in an easy timeline view, calculated from a reliable ephemeris (Swiss-Ephemeris or equivalent) and my preferred ayanamsa. . KP method should also be applied to predicts good timing • Detailed mahadasha / antardasha breakdowns accurate to the second, with plain-languag...
I’m building a peer-to-peer marketplace for fashion where people can list, browse, buy, and sell clothing or accessories—think OLX, but fully tailored to style lovers. Core scope • Users must be able to register and maintain personal profiles. • Each seller should create detailed item listings with images, prices, and brief descriptions. • Buyers and sellers need a secure in-app messaging channel to negotiate or ask questions in real time. Please note: I do not require any rating or review system at this stage; the focus is a clean, straightforward exchange platform. I’m open to your preferred tech stack as long as it delivers smooth performance on Android and iOS and can scale later for web. Include the development of a simple admin dashboar...
The goal is a polished, production-ready class schedule app built with Flutter that ships simultaneously to iOS and Android. I already have screen sketches and the basic user flow mapped out; what I need now is a developer to turn those ideas into a smooth, intuitive experience. Core requirements • Universal build: one Flutter code-base compiled for both iOS and Android stores. • Secure sign-up / sign-in using email-and-password authentication (Firebase Auth fits well, but any reliable alternative is fine). • Three must-have features working end-to-end: – Class reminders: push notifications triggered from the local schedule or a cloud function. – Teacher communication: an in-app chat or message thread between student and teacher, stored in real tim...

I’m bringing to life India’s first real-time marketplace dedicated to limited-edition sneakers and other coveted collectibles. The vision is a transparent bid/ask environment backed by iron-clad authenticity checks, and I want you to architect and deliver the entire stack. Core requirement The heart of the platform is a live bidding engine that updates instantly for every user. Latency has to feel negligible, whether someone is on the web interface or inside the mobile app. Multiplatform reach A seamless experience on both a modern web platform and companion iOS/Android apps is non-negotiable. I expect a shared codebase where it makes sense, yet each surface must feel native and fast. What I need from you • System architecture for the real-time bid/ask flow (web s...

I am about to start Google Play’s mandatory closed-test phase for a new Android app and need 12 separate testers to complete it successfully. Your task is straightforward: accept my Play-Store invite, install the app, keep it on your device for at least 14 consecutive days, and launch it now and then so the Play Console registers active use. No deep bug-hunting, benchmarking, or lengthy surveys—this round is simply to satisfy Google’s closed-testing requirement. If you notice anything odd while the app is on your phone, feel free to drop a quick note, but detailed reports are optional. In return, I’m happy to reciprocate and install your own beta or production app under the same conditions if that helps your metrics—just let me know. To take part, you&rs...
I need a complete mobile survey platform built in either Flutter or React Native, published on both Android and iOS stores. The user-facing app must let people create an account with nothing more than email and password, take available surveys, and receive direct cash rewards that accumulate in an in-app balance. When the balance reaches a threshold they choose, they trigger a payout to PayPal (or a comparable provider I can configure from the admin). The interface should feel professional and sleek—think clean typography, restrained color palette, intuitive navigation, and subtle animations that do not distract from the main goal of finishing surveys quickly. Please integrate Google AdMob banners/interstitials and leave room for optional premium upsells the moment I decide to activ...
I want to turn an existing concept into a fully working mobile application released on both the App Store and Google Play. The scope covers everything from initial technical planning through design, coding, testing, and store submission, with clean, well-documented source code handed over at the end. Key expectations • Universal build for iOS and Android (native Swift/Kotlin or a solid cross-platform framework such as Flutter or React Native—feel free to propose what serves performance and future maintenance best). • Modern, intuitive UI that follows Apple Human Interface Guidelines and Material Design where appropriate. • Smooth onboarding, secure user authentication, and a lightweight backend connection (REST or GraphQL) ready for scaling. • Comprehensi...
I need an Android-only time management app whose core purpose is to keep users on schedule through smart notifications and reminders. The flow is simple: a user sets a task, defines a deadline or ideal start time, and the app nudges them at just the right moments. You are free to choose the framework (native Kotlin/Java or a cross-platform option that still compiles cleanly for Android) as long as the final build is stable, responsive, and Play-Store-ready. I’ll want both an installable APK and full, well-commented source so I can iterate later—potentially adding task scheduling or full time-tracking modules down the road. Key expectations • Clean, modern UI that feels intuitive on current Android versions • Reliable foreground and background notification ha...
I want a clean, lightweight Android application that my field sales team can open, log in with their company email and password, and capture secondary-sales orders on the spot. Two roles matter to me: • Salesman – enters demand, adjusts MRP-based discounts, and submits the order. • Manager – reviews or edits what the salesman submitted and can pull quick reports. The core flow is simple: after login the salesman selects the customer, adds products with quantities, sees the auto-calculated total, applies any discount by percentage or value, and taps “Generate Order”. The app must immediately create a branded PDF containing all line items, MRP, discounts, net values, date/time, and the salesman’s details. That PDF should save locally and be shareab...
I’m ready to turn my idea into a fully-functional Android application and need a developer who can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus. Please let me know: ...
I need a developer who can take my PropTech concept and turn it into a polished, production-ready mobile app for both Android and iOS. The core of the product is a property-listing marketplace, so screens for browsing, viewing details, and saving favourites must feel seamless and fast. A robust search experience is vital: users should be able to filter listings by price, bedrooms, neighbourhood, amenities, and any other field I add later. The search results have to appear instantly, even with thousands of properties in the database. I already have basic wireframes and an API spec for property data. What I need now is someone who can: • Build the full frontend in a shared codebase (React Native or Flutter would keep maintenance simple, though I’m open to native Swift/Kotl...
I am ready to move an end-to-end social networking app from concept to the App Store and Google Play. The core of the product is a clean user-profile system tied to a real-time messaging engine that supports both text and voice exchanges. Beyond the usual social staples, I also want a dedicated “Rotation Pool funds” module that lets groups contribute, track, and rotate pooled money inside the app, so experience with in-app wallets or secure micro-transactions will be essential. Here is how I picture the initial release: • iOS and Android builds written in a shared codebase where practical (React Native, Flutter or similar cross-platform stack is fine, but I’m open to native if you have a strong case). • Secure account creation with email or phone sign-up, ed...
I run a physiotherapy clinic and I’m ready to digitise the way we support patients. I need a cross-platform mobile app that runs smoothly on both iOS and Android and covers three core areas: • Client management – a simple way for our staff to create and update patient profiles, record session notes and track progress. • Appointment booking – patients pick an available slot and the app confirms it instantly, updating our existing calendar in real time. • Exercise video library – short reference clips organised by condition so patients can review their prescribed exercises from home. Everything should be openly accessible; no user registration or login screens are required. A clean interface, straightforward navigation and fast load times are top ...
I’m bringing a brand-new casino-style dice experience—SnapCraps—to market, and I need a full mobile app to make it happen. The hook is simple: every round is run by a live “Game Guru” who can change the odds in real time, so players know they’re facing a human, not a computer. Vegas insiders think this concept can replace traditional craps. Scope • Build one cross-platform mobile app that runs flawlessly on both iOS and Android. • Core mechanics are non-negotiable: players must be able to form teams and go head-to-head against other teams or solo opponents. • Users compete for virtual credits; season leaders earn an invitation to the million-dollar SnapCraps Superbowl held during the NCAA Championship Game. Essential Features &nd...
I run a small personal-training gym and need a no-nonsense mobile app, published on both iOS and Android, that lets our members book one-on-one sessions with ease. The only core feature is personal-training booking, and after any slot is reserved the app must issue a session reminder. Members will create an account and log in before they can schedule, so a simple, secure registration flow is essential. Most of our clients are 60 + years old, so the interface has to be crystal-clear: large, high-contrast buttons, uncluttered screens, and navigation that never leaves them wondering what to tap next. Four or five screens total should cover it—welcome/login, calendar, confirmation, and settings—nothing more. I’m happy for you to work in Flutter, React Native, Kotlin Multipl...

Hazırda həm iOS, həm də Android üçün inkişaf etdirilən bir mobil tətbiqin tam vizual kimliyini yaratmaq istəyirəm. Əsas funksional axın – istifadəçi qeydiyyatı – maksimum rahat və intuitiv görünməlidir, buna görə login, qeydiyyat, profil tamamlanması kimi ekranların hər detalına xüsusi diqqət yetiriləcək. Rəng palitrasını, şriftləri və istinad nümunələrini moodboard şəklində təqdim edəcəyəm və iterativ geri-bildirim dövrü ilə işləyəcəyik. Sənə etibar etdiyim digər məqamlar: • Wireframe-dən yüksək dəqiqlikli mockup-a qədər bütün ekranların hazırlanması • Figma (istəyə görə Sketch) mənbə faylları və kliklənə bilən prototip • Komponent kitabxanası, həm iOS Human Interface Guidelin...
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 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’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...

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...
