    I want to bring the convenience of apps like SHAREit to both Android and iOS . During sign-up the app must collect a name, profile photo, email address, and phone number, then store those details in a secure back-end. Every login has to pass two-factor authentication; email-and-password or even one-tap Gmail sign-in can stay available, yet 2FA is the non-negotiable final gate. Once inside, the user can: • view and manage saved preferences (dark mode, notification choices, default download folder, etc.) • see a per-contact history of every file ever shared, with time stamps and quick re-send options • resume interrupted transfers seamlessly The connection layer should switch intelligently between Wi-Fi Direct and Bluetooth LE for speed and reliability, falling back t...

    I’m ready to turn my social-networking concept into a fully functioning mobile app that feels native on both iOS and Android. The core idea is straightforward—connect people through profiles, a dynamic feed, and real-time messaging—yet the execution must be fast, polished, and secure. Here’s what I have so far: a clear product vision, initial wireframes, and a short feature backlog. What I need next is the complete development cycle—UI refinement, front-end and back-end build, thorough QA, and final store submissions.

    I have a production-ready app that’s tripping over a few specific bugs I’ve already identified. I will share steps to reproduce each issue, along with access to the current code-base and our error logs. Your task is to isolate the root cause, implement clean fixes, then push a fully tested build back to me. The work is strictly about squashing these known problems, but if you spot any low-hanging performance or stability improvements while you’re inside the code I’m open to recommendations. Please be prepared to document what you changed, reference the commits, and confirm that all fixes survive regression testing on every platform we support. Deliverable: • Updated source with the bugs resolved, passing my acceptance tests and ready for release.

Real-time communication is just as important. I want patients to launch an HD video or audio session with their doctor from inside the app, include in-call chat, share their screen for document review, and have the entire consultation automatically recorded (with consent) for later playback.

    A streamlined productivity app centered on task management needs to be built from the ground up for both iOS and Android. Core flow is simple: users create a task, set priority and due date, receive timely reminders, then mark the task complete.

To get there I need the full workflow covered: secure sign-up/login, profile editing with a “price per call” field, in-app balance or card checkout, and a reliable voice stack (Twilio, Agora, WebRTC—whichever you’re most comfortable with).

    Flutter AQI App Development
    6 days left
    Verified

    I already have a complete Figma file for a compact air-quality mobile app and now need it brought to life in Flutter for both iOS and Android. The core feature is a clean, real-time display of the Air Quality Index (AQI) pulled from an open data API; PM2.5, PM10, or ozone values are not in scope right now, so the interface stays minimal. A lightweight social-media login (Google, Apple or Facebook—whatever is fastest to set up with Firebase/Auth0) should greet users on first launch, after which the app lands on the AQI dashboard. All screens, colours and component specs are waiting for you in Figma; I simply need pixel-perfect implementation, smooth state management, and builds ready for TestFlight and Play Console. Deliverables • Flutter source code matching the Figma design...

    1973 Coup AR MVP Build
    6 days left
    Verified

    I am building 1973AR, a location-based mobile experience that lets visitors walk through Paseo Bulnes and the surroundings of La Moneda while reliving the key moments of the September 11, 1973 coup d’état. Historical accuracy is already documented; what I now need is an XR-savvy developer (or small team) who can turn that research into a living, geolocated narrative focused on immersive storytelling and interactive scenes, running smoothly on both iOS and Android. The prototype must: • lock 3-D content to precise GPS coordinates along the route, using ARKit/ARCore (cloud anchors or a similar solution) • blend spatial audio with authentic sound archives so visitors feel helicopters overhead, speeches echoing from balconies, and distant sirens in real time &bul...

    I have a React Native app running on the Expo managed workflow, with a Node.js backend and a small React.js web companion. I now need rewarded ads from Google AdMob added to the mobile build for both iOS and Android. Here’s the exact flow: after a user successfully completes a task in the app, they should immediately see a rewarded ad. No banners, no interstitials—just the single rewarded unit. Expo’s latest SDK, expo-ads-admob (or the bare AdMob API if you prefer ejecting), and proper configuration of the AdMob app- and ad-unit IDs are all fair game, as long as the final binaries pass Google’s test ads and production ads alike. Deliverables • Code changes or modules integrated into the existing repository • Brief README or screencast that shows wher...

    I need a revolutionary app using React Native for Android, iOS, Web and Desktop (webview but Mac and Windows App). The app is about Instagram, but with new more elements than today's original instagram. You can browser the web. You can play inside it. Why? Because it is a mix and includes banking, Google Chrome, Instagram, and WhatsApp all inside it. It looks exactly the same as Instagram today. But it is more turbo. Like, in the mobile version, it has a bottom bar for AI questions. Like Gemini. Imagine the app like you can use Instagram, Gemini/ChatGPT, Excel, Word, WhatsApp all inside it. So it will need documents and table creation. It will include all worlds main apps inside it. But it looks exactly the same like Instagram because think... the 2 billion people from Instagram will...

    I already run a web-based AI chat service with a fully documented REST/WebSocket back-end in production. What I am missing is a polished mobile companion that talks to those same endpoints and exposes every mode of conversation we currently offer—plain text, voice notes and live video—on both Android and iOS. Here is what I need from you: • A single code-base (Flutter, React Native or similar) or two native projects that compile into a store-ready Android build and an iOS build. • Seamless routing of text, voice and video streams through the APIs I will supply; no new server work is required. • A clean chat UI/UX that launches straight into a session—there is no user registration or login step. • Basic in-app settings (theme toggle, mic/camera ...

    I already have a published Android puzzle-style utility game and I’m looking for a long-term developer who can take full responsibility for keeping it healthy on Google Play. The codebase is stable, written in Kotlin with Android Studio, and it currently runs on the latest SDK, but I need someone to step in and handle everything from hosting in the Play Console to incremental feature updates and quick hot-fixes when user feedback rolls in. Here’s what I expect in our collaboration: • First, review the existing source, set up your own build environment, and confirm a clean release build. • Next, migrate—or simply verify—Play Console settings, signing keys, release tracks, and Crashlytics or Firebase analytics so crash reports and ANRs are always visible....

    I already have a sizeable repository of ready-made game scripts, assets, and demo scenes. The core mechanics compile, but the project still needs structured integration, bug fixing, and a clear path to a publishable build. Platform and genre are flexible at this point—we can keep it mobile, web, or desktop depending on what the current modules suit best, and I’m open to your professional advice. Here’s what I need next: • Audit the current codebase, remove redundancies, and squash obvious bugs. • Hook up any missing systems—audio, save/load, input mapping, lightweight AI, and UI polish. • Assemble a playable vertical slice that clearly demonstrates the core loop. • Produce a clean, well-commented build that runs on at least one platform (A...
