I’m building a brand-new tracker aimed at hunters and other outdoor enthusiasts who need to see the location of their harvested game is in real time. The core requirement is straightforward: reliable location tracking that appears instantly on a smartphone and must be as small and light as possible. The idea is that a bow hunter can easily track and find their game after a shot is taken. This would ideally be the most ethical form of locating an animal to ensure that it is not gone to waste. Here’s the functionality I have in mind: • The device gathers GPS coordinates, pushes them to the user’s phone over low-energy Bluetooth, and refreshes quickly enough to feel truly live. • When Bluetooth isn’t possible or range is lost, a secondary short-range...

I want a true Bluebook-style application that lets students sign up with email verification, log in securely, and sit for timed SAT Math sections. The same codebase should compile cleanly for iOS and Android phones as well as native Windows and Mac desktops so students can practise on any device they own. Core flow • Student creates an account, verifies via emailed link, and lands on a simple dashboard. • From there they can launch a full-length math section that mimics official SAT timing, auto-advances after each question, and locks once time expires. • At the end of the session the app instantly scores the attempt, shows the correct answers with explanations, and saves the record for later review. I will supply the question bank in CSV; the app just needs an import rout...

I need an end-to-end slot-booking solution that works seamlessly on iOS, Android, and any modern web browser. The goal is to let people find an available playground, lock in a time, and manage any last-minute changes without headaches—while giving venue owners and my own admins the control they need behind the scenes.

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 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’m launching a worldwide singles fraternity—“Grupo Honest Singles”—designed to connect genuine people while giving special visibility and support to carefully selected owner-operator businesses. To make this vision accessible everywhere, the community needs to live both on the web and on mobile. The build covers a responsive website plus companion apps for iOS and Android that mirror the same core experience. Members should be able to create rich profiles, search and interact with one another, and discover businesses we endorse through a dedicated support section. Security and ease of entry matter, so the platform must allow account creation and sign-in through standard email/password as well as popular social logins. Key deliverables • Fully branded...

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...
I am building a digital pass that fans can drop straight into Apple Wallet and pull up whenever they want to see where I’m spinning next. The pass only needs to present three things clearly: the current event details, my up-to-date contact information, and a short music sample that sits behind a link to an external source (no embedded audio, no interactive booking flow for now). I already have artwork and the audio link ready; what I’m missing is someone comfortable with PassKit, Swift and the current Wallet specification who can generate the .pkpass file, sign it properly, and show me how to update the JSON so I can push new dates or tracks in the future. Compatibility across iOS 15+ is essential. Deliverable: a production-ready pass (.pkpass) that installs without warni...
The goal is a polished, production-ready class schedule app built with Flutter that ships simultaneously to iOS and Android.

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 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 have an AI-generated sales app already designed for iOS and now need a specialist who can take it from my Xcode project to a live, smoothly running product in the App Store, then keep it healthy as user numbers grow. The current build focuses on secure user authentication—no product catalog or order processing yet—so the priority is to stand up a rock-solid sign-in flow, connect it to a reliable back-end (Firebase/Auth0/AWS Cognito, whichever you prefer and can justify), and comply with Apple’s guidelines on data privacy. Once the app is accepted, I’ll rely on you for versioning, TestFlight roll-outs, crash monitoring, and incremental updates generated by my AI design pipeline. Swift, Xcode, Git, and App Store Connect will be your everyday tools here; if you...
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 already have a functioning VPN app in the App Store and now need a skilled iOS developer to take it to the next stage. The immediate priorities are: • Integrate Apple’s StoreKit framework so users can purchase and manage subscriptions from inside the app. The flow must cover free-trial, monthly and yearly plans, handle renewals, restore purchases and surface any StoreKit errors gracefully. • Add a one-tap speed test that pings every available VPN server, displays latency / throughput in real time and caches the latest results for quick comparison. • Implement automatic server selection that chooses the fastest available node at launch or whenever the current connection drops, with a seamless hand-off so the user never notices the switch. The existing codebase i...
I have two software initiatives that need to move from concept to release: an intuitive video-editing application and a companion tool for building modern, responsive websites. For the video editor, I want users to be able to import clips, trim, rearrange and export with ease. Once the core workflow is rock-solid we can layer in more advanced functions—think multi-track timelines, chroma-key, voice-over or anything else you can justify from a performance and UX standpoint. Suggest the framework you feel best balances speed, portability and long-term maintainability; I’m open to native iOS/Android, Flutter, React Native or even a desktop build if that proves wiser. The web-development app should let non-technical users assemble clean, standards-compliant pages through a drag...
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...
I need a dependable partner to turn my app idea into a polished, production-ready product while also setting up a straightforward contact form on our corporate site. For the app itself, I already have the core concept and basic user flows drafted; I now want you to handle everything from architecture and UI to final store submission, ensuring clean, well-documented code (Swift/Kotlin or cross-platform React Native/Flutter—whichever you feel best suits long-term maintainability). On the web side, the requirement is simple yet essential: a secure, spam-protected contact form that feeds directly into our CRM and triggers an email notification. It has to match the existing corporate design and be GDPR-compliant. Deliverables • A fully functional, tested mobile app (iOS &a...

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 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 am commissioning a bilingual iOS application—Arabic first, English second—that delivers live Bitcoin and selected-coin data with a professional, sleek interface entirely in Swift and SwiftUI. The app’s core revolves around real-time price feeds, historical price charts, and razor-sharp alerts that keep users ahead of major market moves. Arabic users will enjoy a true RTL layout, while English users see a standard LTR presentation, all driven by Apple’s native localization tools. Key functionality I need implemented: • Current price updates streamed from a reliable REST source • Historical price charts for deeper context • Push notifications for major price changes via Firebase Cloud Messaging • In-app alerts that surface whale activity...
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...
My Flutter app is finished and tested on my end; what’s left is to get it live on both Google Play and the Apple App Store. I already have active developer accounts for each platform and all listing assets—screenshots, icons, long/short descriptions—are prepared. I simply need someone who knows the submission pipelines inside-out to take the project across the finish line. Here’s what I’m looking for: • Build & sign the final release packages (AAB for Google Play, IPA for iOS) or validate the ones I provide. • Upload everything through Play Console and App Store Connect, filling in required metadata, privacy labels, content ratings and policy declarations. • Set up closed/internal testing: Google now mandates tester access prior to pu...
source code: My current code-base is written entirely in Swift and already live in Xcode; however, it now needs a solid refresh. I want the project audited, improved, and extended where sensible—this may include streamlining the UI, tightening performance, or wiring in a few new features that have been on the backlog. You’ll start by reviewing the repository (Git), reading the short README I’ve written, and walking me through any questions so we can prioritise tasks together. Once the roadmap is clear, go ahead and: • refactor or redesign modules that slow the build or affect user experience, • implement the agreed-upon feature enhancements, • tidy up comments and add inline documentation where the logic is non-trivial, • deliver a concise ...
