I am building a new cross-platform mobile product and plan to base it on React Native for the client and Firebase for all backend services—authentication, real-time database, cloud functions, and storage. The project also calls for a polished UI created in Figma before a single line of code is written. While React Native and Firebase are my first choices, I am open to hearing how Flutter or Supabase might add value if you have a compelling case. Scope at a glance • Design: Wireframes through to interactive, developer-ready Figma files that capture the complete user journey. • Mobile: Clean, well-architected React Native code that feels native on iOS and Android, integrates smoothly with Firebase, and is ready for store submission. • Backend: Secure Firebase s...
I need a full-stack team that can create an Urban Company–like ecosystem focused on appliance repair. The build must cover a responsive website plus native apps for both iOS and Android, all sharing one backend so data stays perfectly in sync. Core functions I want ready on day one: • Service booking with smart scheduling that matches customers to nearby technicians. • A secure payment gateway so users can pay within the app or site without redirection. • Real-time service tracking that lets customers see when the technician is en-route and when a job is complete. Clean, intuitive UX is essential, and I will supply the brand guidelines and initial wireframes. Please base your quotation on a phased rollout: MVP with the three features above, followed by any nice-t...

I have built an app using Lovable, the app is a social networking app concept I need you to export the app from lovable and successfully launch it on 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've done for 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 y...

I urgently need a seasoned Android engineer to take a brand-new idea from concept through to a fully working application. The exact feature set is still open for discussion, but whatever we build must run smoothly on both the latest devices and older phones and tablets without breaking UI or functionality. You will handle architecture, coding, testing, and deployment to Google Play, providing me with the full source code and a signed APK at each milestone so I can track progress. Expect to optimise for performance, follow modern Material guidelines, and implement solid backward-compatibility strategies—whether that means leveraging AndroidX, shrinking the APK with ProGuard/R8, or tailoring layouts with resource qualifiers. Clear, well-commented Kotlin or Java, Git-based version...
I am looking for a freelancer who can provide 15 reliable testers for my Android VPN app ("Call Sweet") to meet the Google Play Console "Closed Testing" requirements. The Goal: My app needs to be tested by real users for 14 continuous days to get approval for the Production track. Requirements: 15 Testers: Even though Google asks for 12, I need 15 testers to ensure a safety buffer in case someone drops out. Real Devices: Testers must use real physical Android devices (no emulators). Opt-In & Install: All 15 testers must accept the invitation link, download the "Call Sweet" app, and keep it installed for 14 continuous days. Active Testing (Important for VPN): Since this is a VPN app, testers must open the app daily and click "Conn...

I am looking for a developer who can turn my idea for an Android-only social networking app into a polished, launch-ready product. The core experience should let users register quickly, build a profile, connect with others, share posts (text, photo, or video), react or comment, and chat in real time. A clean Material design, smooth performance on recent Android versions, and push notifications are essential. I plan to monetise later, so the codebase needs to be structured for easy integration of ads or in-app purchases. If you are comfortable working natively in Kotlin or Java and have handled cloud back ends such as Firebase, Supabase, or a comparable stack, your expertise is exactly what I need. Security best practices, scalable database design, and simple analytics hooks all matter to ...

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.

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...

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.

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...
Ho già un’app multipiattaforma funzionante e ora desidero pubblicarla sia su Apple App Store che su Google Play Store. Mi serve un professionista che curi l’intero processo di messa online, incluse le configurazioni di certificati, provisioning profile, bundle ID, schede store localizzate e verifica delle policy di entrambe le piattaforme. Oltre alla pubblicazione voglio perfezionare tre aree chiave già presenti nell’app: • Notifiche push – configurazione e test end-to-end. • Integrazione con social media – login, condivisione contenuti e deep-link where necessario. • Analitica e monitoraggio – attivazione eventi personalizzati e reportistica per iOS e Android. Una volta che l’app sarà approvata richiedo as...
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 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...
My dating app is already coded, tested, and running smoothly; now I need it live on both the iOS App Store and Google Play. I hold active developer accounts for each storefront, so provisioning profiles, certificates, and console access are ready for you from day one. Your task is strictly the release process: create production-ready builds, prepare store listings, configure in-app settings (privacy, screenshots, icons, descriptions, age rating, policies), submit for review, and shepherd the submission through until both stores show the app as publicly available. I will supply all design assets and copy; please feel free to suggest improvements if you see any compliance or optimisation issues. Deliverables I will sign off on • Signed, versioned IPA and AAB/APK bundles successfully...
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.

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 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...
Saya ingin memiliki sebuah aplikasi game mobile sederhana yang dapat menghasilkan pendapatan utama melalui iklan. Target saya jelas: “Menghasilkan pendapatan dari iklan” pada sebuah aplikasi game, bukan tipe aplikasi lain. Gambaran umum – Platform: fokus pada mobile (minimal Android; jika memungkinkan iOS sebagai opsi tambahan). – Monetisasi: integrasi jaringan iklan populer seperti Google AdMob atau alternatif setara. Iklan banner, interstitial, dan rewarded video harus diatur agar tidak mengganggu pengalaman bermain namun tetap efektif untuk pendapatan. – Gameplay: cukup kasual agar mudah dipelajari, ringan dijalankan di perangkat low-mid range, dan mendorong sesi bermain berulang. Contoh gaya permainan endless runner, puzzle sederhana, atau arcade t...
