My productivity app is already coded, signed and has even been through App Store Connect once, but Apple rejected the submission. I’m looking for someone who can diagnose the review notes, adjust whatever is blocking approval—whether that’s in the code, entitlements, privacy wording, or the metadata—and then guide the build all the way to “Ready for Sale.” Here’s where things stand: • The app is fully built and functions correctly on test devices. • I have several of the required listing assets (icons, basic screenshots) but need help finishing the set and formatting them to Apple’s exact specs. • I can give you full access to the Xcode project, App Store Connect account, rejection correspondence and TestFlight builds. ...

I need a Flutter iOS developer to fix two small but visible issues in my live app and then push the corrected build to the App Store. First, the “Share Invites” and “Invite Guest” buttons are currently unresponsive on iPhone; the dialog flashes on screen and closes immediately. I need that behavior fixed so the pop-ups remain active and function as intended. Second, within the attendance workflow I want a third RSVP choice. Right now users can tap only “Yes” or “No.” Please add a “Maybe” option wherever an RSVP update is made. Simply, fixes needed: 1 - Share invites (csv) 2 - Invite guest 3 - Maybe (guest invite) If you have recent experience with Flutter apps on iOS and can turn this around quickly, let’s get started...

I’m building an end-to-end lending experience for iOS that feels as smooth as Slice or Moneyview. The job covers both sides of the stack: a sleek native iOS front end and a secure, scalable back end with the APIs that power it. On the user side the flow is simple but must be rock-solid. A new customer signs up with email/password, can just as easily use a social account, and once inside can enable Face ID or Touch ID so returning is frictionless. They complete a loan application form, the system instantly checks eligibility, returns an approved amount (or declination), shows a clear repayment schedule, and later lets them review every past loan in a dedicated history screen. I need the full technical delivery: • iOS app (Swift or SwiftUI preferred) that implements the entire j...

I’m building “Mind Intellectual”, a mobile-only learning platform that pairs structured courses and tutorials with built-in quizzes and assessments so users can immediately test what they’ve learned. I already have the subject matter mapped out; what I need now is an end-to-end app that makes this content engaging and easy to navigate on any modern phone. Here’s what matters most to me: intuitive screens for browsing courses, a smooth lesson player that supports text, images, or short videos, and a quiz engine that can handle multiple-choice and true/false items while storing each learner’s results for later review. User progress tracking, basic push notifications for lesson reminders, and a lightweight admin area where I can upload new material round o...

I need a full trio of mobile applications—customer, restaurant, and delivery—to replicate the seamless food-ordering flow you see in Swiggy or Zomato. The entire solution has to ship for both iOS and Android from a single code-base or parallel native builds; the choice of Flutter, React Native, Kotlin/Swift, or another modern stack is up to you as long as performance and store compliance are rock-solid. Core requirements for the customer-facing app: • Restaurant search and discovery with location awareness • Real-time order tracking from placement to doorstep • Secure, multi-provider payment gateway integration (cards, UPI, wallets) The restaurant app should let partners accept or decline orders instantly, update preparation status, and manage item availabi...

I’m getting ready to broadcast a mobile-based gaming session live on YouTube and want everything to look and sound professional from the first second on-air. I’ll be running the show through Streamlabs, so what I need now is an experienced hand that can fine-tune the app, design tidy overlays, balance audio, and walk me through the optimal settings for a phone-captured feed. The workflow I’m picturing is simple: we hop on a call, you remotely guide me while I screen-share, we build the scenes together, add the alert boxes, test bitrate and resolution, and then run a short private test stream to be sure the chat, notifications, and capture are rock solid before launch. If anything glitches, I’d like quick troubleshooting advice so I can fix it on the spot during fut...

I’m commissioning a full, production-ready ride-sharing solution that covers both sides of the marketplace. The scope spans native iOS and Android rider apps, a mirror set of driver apps, plus the server stack that powers real-time matching, payments, and dashboards. Core workflow • Riders open the app, watch nearby drivers update live on a map, request a trip, and pay securely with a credit or debit card. • Drivers toggle their availability, receive requests, navigate via in-app GPS, then review completed trips and earnings. • The backend matches riders to drivers instantly, calculates distance-based fares, and settles transactions to the appropriate accounts. Key components to build • Two mobile apps (Swift/SwiftUI for iOS, Kotlin/Jetpack for Android) ...

I’m turning the first version of my mobile product into reality and need one dependable developer to own the build and guide the technical choices along the way. We’ll work in FlutterFlow or Bubble—whichever you believe will get us to market fastest—on top of a Firebase backend. I’ll handle product direction; you’ll handle code and architecture. Clean functionality is the goal, not pixel-perfect polish. The MVP must launch with: • User profiles (avatar, basic settings) • Real-time messaging between users • A content-sharing area (text, images, short video) The UI style should feel modern and colourful while remaining intuitive. I’m aiming for a working build as soon as possible, so I expect a short progress demo or Loom walkt...

I’m planning to launch a simple yet solid music-streaming application that runs natively on both Android and iOS. The core focus is a clean audio player that fetches and streams tracks from my back-end, with social-media login (Google, Facebook, or Apple) as the only authentication option—no email/password flow needed. I’m flexible on the tech stack: if you favour Flutter, React Native, Kotlin Multiplatform, or native Swift + Kotlin, that’s fine as long as the end result feels fast, modern, and stable on each platform. UI/UX assets, API endpoints, and sample tracks will be provided. Deliverables • Fully functioning Android and iOS apps compiled from a single codebase or two native projects • Social-media sign-in wired up and returning a valid user toke...

I want to turn “Wirna Mendrofa” into a polished mobile application and need a developer who can handle the full software-development cycle—from architecture and UI all the way to store submission. The finished product should run smoothly on both iOS and Android; how you reach that goal (native Swift / Kotlin, React Native, Flutter, or another framework) is up to you, so long as performance and maintainability stay top-tier. To be considered, send me a detailed project proposal. Walk me through your suggested tech stack, development milestones, testing process, and maintenance plan, and include links to any similar apps you’ve built so I can see your past work in action. Clear, well-commented code in Git, regular testable builds, and comprehensive deployment notes ...

I want a single code-base app (React Native or Flutter is fine if it meets Apple and Google policies) that lets my users save any public video or audio they encounter online—Instagram Reels, YouTube clips, Facebook posts and beyond—directly to their device with zero watermark. The app must automatically detect the highest available quality, then offer MP4 for video and MP3 for audio before placing the file in a tidy, built-in library. Core flow • Paste or share a link into the app • Choose format (MP4 or MP3) and resolution/bitrate • File downloads in the background, lands inside an in-app folder structure the user can rename, move or delete • Play instantly through the integrated player or export to the camera roll / files Account & membership...

I need a straightforward yet polished online-shopping app for my supermarket, available on both iOS and Android. The primary goal is letting customers browse products and place orders from their phones; everything else is secondary to a smooth buying experience. Because I’m not on a tight deadline, you’ll have the freedom to choose the tech stack—native Swift/Kotlin or a cross-platform approach such as Flutter or React Native—so long as the final result feels fast and intuitive. Key deliverables I’d like handed over: • Shopper-facing app for iOS and Android, ready for App Store and Google Play submission • Clean, well-documented source code • Simple admin or API hook that lets me update products, prices, and stock in real time • I...

I’m ready to commission the first release of a security-focused mobile application, launching on iOS before we expand to Android. The core of the product is continuous GPS tracking that must keep running in the background without draining the battery or being shut down by the OS. To protect sensitive medical data every byte stored on-device has to be encrypted and locked behind biometric authentication (Touch ID / Face ID) with an optional 4- to 8-digit passcode fallback. When pre-set conditions are met—location reached, time elapsed, or user action—the app should automatically issue push notifications to the user (and later to caregivers via a secure service we will integrate). Security is non-negotiable: please design with Secure Enclave, Keychain storage, SSL pin...

I need a skilled Flutter developer to plug a very specific feature set into my existing kids-focused mobile app. The task is all on the client side: build AR camera filters that work with ARCore on Android and ARKit on iOS, track individual eye movements in real time, and capture short videos at defined moments, then push those clips to a REST endpoint that is already live and documented. You will wire up the camera feed, layer the AR assets, implement per-eye tracking accuracy (not just general face gestures), trigger recording when my code tells you to, and send the resulting MP4 to the backend with the required headers and auth token. No UI beyond a minimal overlay is expected, so you can concentrate on the functionality itself. Deliverables • Flutter module(s) that expose AR f...

I need an iOS app built around entertainment, with music playback at its core. The must-have capability is allowing users to create and manage playlists smoothly. Everything—UI, backend logic, and audio handling—should feel native, fast, and reliable on the latest iPhone and iPad devices. Here’s how I picture the first release coming together: • A clean Swift-based codebase that leverages AVFoundation (or another Apple-approved audio framework) for seamless playback. • An intuitive interface where users can browse tracks and build, edit, and reorder playlists in just a few taps. • Persistent storage so playlists survive app restarts and device reboots. • Polished UX details such as artwork display, scrubber controls, and smooth transitions bet...

I am building a cross-platform music learning application and need a seasoned mobile developer who can take it from concept to App Store and Google Play launch. The heart of the product is a multi-audio player that streams (no local download) and offers rock-solid playback controls—play, pause and stop must feel instant and glitch-free even on low-end devices. Smooth buffering, background audio, and graceful interruption handling are essential. Around that player, we’ll layer three distinct account types—Students, Teachers and Admins—each seeing only the tools they need. Students subscribe (monthly, quarterly, yearly plans), browse lessons, and record their own performances directly in the app to submit for feedback. Teachers will be able to review those recordings...

Hi, I’m exploring the development of a local-focused social media app for small businesses and wanted to see if you’d be open to a brief conversation. The MVP is simple: verified businesses post photos/videos to a scrollable feed; customers can follow and comment. No payments or subscriptions in the first version. Launching in one city first. If this aligns with your experience, I’d love to discuss timeline, cost range, and tech stack. Best,

The entire focus is on smart task management—no alarms, no file organisers, just an intuitive way to create, edit, prioritise and mark off tasks on the go. Core requirements • Native-feeling experience on each platform, whether you work in Swift/Kotlin or a solid cross-platform stack such as Flutter or React Native. • Fast, searchable task lists with categories, deadlines and basic push notifications. • Local persistence with optional cloud sync so a user can pick up exactly where they left off on another device. • Modern, accessible UI that meets Apple App Store and Google Play guidelines. Deliverables - Clickable high-fidelity mock-ups approved before coding b...

I need a fully working antivirus application for macOS written in Swift or Objective-C. The core requirements are: • Real-time, on-access scanning that runs quietly in the background and intercepts file events at the filesystem level. • Automatic definition and engine updates pulled from my update server without user interaction. • Automatic quarantine: as soon as malware, adware, or spyware is detected, the file should be isolated in a secure location and flagged for review. No user prompt should appear before the item is moved. At minimum I expect: 1. A native macOS app bundle with sandbox-safe helper tools and any required kernel/system extensions or EndpointSecurity integration for live file monitoring. 2. A simple UI that shows scan status, last update time,...

I'm seeking an experienced app developer to create a real-time lottery application for iOS. The app features: - Live prize pot that updates instantly - Digital wallet for payouts - Secure lobby - "My Tickets" vault with cryptographic safety Ideal candidates should provide detailed project proposals and have experience in developing secure, real-time updating applications. Strong familiarity with iOS development and user authentication systems, particularly email and password, is essential.

I’m after verybasic proof-of-concept that demonstrates LiDAR-based 3D scanning on iPhone using Swift, ARKit/RealityKit, or any other native approach you find effective. When the app launches it should show a single button; tapping that button starts the LiDAR scan, stopping it generates one STL file (the only required format). Right after processing, the mesh needs to: • display inside the app so I can visually confirm the scan, and • be saved locally for offline access. Would be great if can be uploaded on gdrive if that doesn't add lotof work for this prototype. Performance is important—I’ve tested similar code in “Antigravity” and know the device can handle fast reconstruction, so I expect comparable speed here. No fancy UI, NO spla...
