I’m ready to bring GoGo Delivery to life with a dedicated iOS app. The focus is on a rock-solid first release that lets users create an account, place a delivery request, track their courier in real time, and receive push-notification updates until the hand-off is complete. A lightweight driver view (login, route overview, status updates) should be included so both sides of the experience work seamlessly. Here’s what I need from you: • A clean, Swift-based codebase that compiles on the latest Xcode version. • Simple, intuitive UI that follows Apple’s Human Interface Guidelines. • Secure sign-up/login (Apple Sign-In preferred). • Order flow: address entry, service selection, payment stub (ready for Stripe or similar), live status updates. &bull...

I need an experienced developer to convert my iOS app to Android. The Android app will have the exact same design as the iOS version. The app is called Qualuff Puzzles and is available in the App Store for Apple devices. It is a collection of acrostic crossword puzzles where letters in the answers to clues are linked to letters in a quote that the user is trying to figure out.

I want to bring to life a lightweight iPhone app that can recognise scratching episodes just from the handset’s own motion sensors—primarily the accelerometer and gyroscope. My vision is for everything to be processed on-device so the user’s data stays private, yet I’m open to exporting raw events to a small backend later if that proves cleaner for post-processing or model updates. For detection I’m leaning toward a hybrid approach: a simple rule layer to filter obvious noise and an embedded Core ML model to learn the subtler patterns. Push notifications should warn the user whenever their scratching crosses a configurable daily threshold, and a single screen will show the time-stamped events plus a rolling daily and weekly summary. A basic settings view is ...

My production-ready mobile app runs on both iOS and Android and I’m looking to roll out a focused round of bug fixes. The core codebase is already stable in terms of features, so no new functionality is needed right now—this engagement is strictly about identifying, reproducing, and resolving the issues users are reporting. Scope of work • Audit recent crash logs, error reports, and edge-case defects I will share from App Store Connect and Google Play Console. • Pinpoint root causes, patch the code, and supply clean, well-commented commits. • Regenerate release builds for TestFlight and internal Play testing so I can verify fixes before public release. • Once confirmed, assist with submission steps to both stores. Acceptance criteria 1. All liste...

I’m building a focused mobile social network where the only thing that matters is sharing photos and videos. The scope is deliberately slim—no messaging threads, no sprawling profile pages—just a fast, elegant feed that lets users capture, upload, browse, and react to visual content. Here’s what I need from you: • A cross-platform mobile app (native Swift/Kotlin or a solid framework like React Native or Flutter—happy to follow your expertise) • Core features: camera capture, local gallery import, real-time upload with progress, adaptive feed that autoplays video, basic like/comment counters, and simple account creation via email or social sign-in • Clean, modern UI that feels at home on both iOS and Android, with smooth transitions and ges...

I am looking for a Senior macOS Code Signing & Notarization expert to diagnose and fix a persistent "Status 7000: Team not configured" error. THE CRITICAL CHALLENGE: Most developers will suggest using the App Store Connect API Key to fix this. I HAVE ALREADY TRIED THIS, AND IT FAILED. I need an expert who understands why xcrun notarytool returns Error 7000 even when using a valid API Key and fully paid accounts. The Context: Accounts: I have TWO Apple Developer Accounts (Personal and LLC). Both are fully PAID and all agreements are ACTIVE/GREEN in App Store Connect. The Target: I am currently testing with a simple "" (dummy file) to isolate the issue from my Electron source code. The Result: Both accounts fail with statusCode: 7000. The Technical Evidence (Log...

I have two iPhones on two different carriers: my daily number sits in an iPhone SE running on Tigo, and my newer iPhone 16 is on another network. I want every call that reaches the SE to ring on the 16 instead, so I need someone to walk me through activating, testing, and troubleshooting call forwarding on the SE only. You’ll guide me step-by-step—screenshare or clear written instructions are both fine—until: • Call forwarding is switched on in the SE settings (Tigo’s USSD or menu method, if required) • A live test proves the 16 rings immediately when the SE’s line is dialed • Voicemail and missed-call behavior stay intact or are adjusted as we agree We can coordinate over Zoom, FaceTime, or any tool you prefer. Experience with iOS 17+ ...

I would like to create a mobile app for IOS, which allows end-users to manage a dialog with a server either via textual chat or via voice commands. I see it organized in three screens: 1. log-in and authentication (username [email] /password). Only one 2. avatar selection (man / woman). Only once 3. main screen where we have an 'talking' avatar, the textual chat window and the mic button to speak. The dynamics is the following: Once the app is launched, the main screen is opened with a greeting by an avatar. A user gives a command (either via texting in a chat window or verbally, by pressing the mic button). In case of a voice command, it translated to a text, presented in the chat and sent to a server through provided API. Then a textual response coming from a server , reflected...

I have an app that is being developed. It's almost complete, but one main function does not work properly as intended. The app listens for a keyword, and when it hears it, it opens up Google and displays that word in the search results. Some of the time, it should display the synonym of that word. It will either display the exact word or the synonym of that word, depending on the percentage slider in the settings page. You need to make sure that it displays the synonym or the exact word according to the percentage set in Settings. But the main problem is: sometimes it hears a word such as "Pension" but it only outputs half the word as "Pen" or instead of "Crypto" it outputs "Cry". So this needs to be fixed and completed. The previous devel...

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 building an iOS app and need short, recurring remote sessions on real Apple hardware to compile, sign and push new builds to TestFlight / the App Store, then verify behaviour—especially VPN and network flows—on a physical device. Here’s what I’m after: • A Mac with Xcode already set up. • A real iPhone tethered to that same Mac so I can install the build directly. • Remote control via Chrome Remote Desktop (that’s my preferred tool, although I can adapt to AnyDesk if you already have it configured). • Solid internet and the ability to jump on quickly when I have a new build ready—sessions will be brief but may repeat often. When you reply, please include: 1. macOS version running on your Mac. 2. Exact iPhone mo...

I’m seeking a senior iOS developer to build a well-defined iPhone app using SwiftUI. The app is local-only by design: no accounts, no cloud storage, no backend services, and no analytics. All data is stored securely on the device. I have a detailed written spec and task checklist and am looking for the app to be built exactly to that scope, without feature expansion or architectural changes. Important constraints: This is a tightly scoped MVP. • iOS only • SwiftUI + SwiftData • Local-only data storage (on device) • No backend, no cloud sync, no analytics, no user accounts • Minimal UI polish required (clean, functional, Apple-standard UI is sufficient) Please do not propose additional architecture, services, or features outside this scope.

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...

I’m ready to turn a simple idea into an elegant iOS application that helps archers record and review every shot. The scope is focused and clear: • Core functionality must cover rapid score tracking during a round, an in-app leaderboard to compare results with friends or club members, and a historical performance section that stores past sessions for later analysis. • Native iPhone development only—I’d like this built with the current iOS SDK, using Swift or SwiftUI if that fits your workflow. • Clean, minimal UI is important; entering scores has to feel effortless even on the shooting line. • All data should persist locally and continue working offline, then sync to the leaderboard when a connection is available. • I’ll need a short...

I need a mobile application that lets users watch their CCTV cameras in real time, store recordings in the cloud, and pay for access through in-app subscriptions. The core build must cover both iOS and Android so customers can smoothly switch between devices without losing footage or settings. Key requirements • Live streaming: low-latency playback with adaptive quality up to Full HD. • Cloud storage: automatic upload of recorded clips to a secure bucket (AWS S3, Google Cloud Storage, or a comparable service). Users should be able to browse, scrub, and download past events. • Subscription management: native in-app purchase flows (Apple/Google) to unlock storage tiers and additional features. Handle renewals, grace periods, and failed payments gracefully. I’m ...

I am looking for a macOS Code Signing & Notarization expert to fix a persistent "Status 7000" error on my local machine. The Situation: I have an Electron application, but I am testing with a simple "Hello World" zip to isolate the issue. I have two Apple Developer Accounts (one Personal, one LLC). CRITICAL: Both accounts are fully PAID (Apple Developer Program) and all agreements (Free/Paid Apps) are ACTIVE/GREEN in App Store Connect. The error persists on BOTH accounts when using the standard password/keychain authentication. The Evidence (Fails on BOTH accounts): I tried notarizing with both my Personal and LLC accounts. Both return the same blocking error: Attempt 1: Personal Account (Standard Auth) log admin@Admins-iMac % xcrun notarytool log [JOB_ID_RE...

As discussed, I’m ready to move ahead with complete mobile app development for both iOS and Android. All UI flows, feature priorities, and API endpoints were shared previously, so you can jump straight into implementation. Deliverables • Production-ready code for iOS and Android • TestFlight build and signed APK for review • Clear build/run instructions and brief technical documentation We will follow the milestone schedule we already outlined. Let me know if you need anything else before you start coding.

I’m ready to have an iOS mobile app built that lets users buy, sell, and interact in one place—think of a lightweight marketplace threaded with social features such as follows, likes, and direct messaging. The core concept is simple: products and people share the same spotlight. Here’s what I need brought to life: • Native iOS build in Swift or SwiftUI, cleanly architected and prepared for future feature drops • Seamless onboarding with Apple Sign-In plus standard email/phone registration • Seller tools for listing items (photos, price, short description, stock status) and editing on the fly • Social layer: personalised feed, comments, likes, user profiles, and real-time chat between buyers and sellers • Secure in-app purchases or Stripe-...

I’m ready to commission a secure, user-friendly cryptocurrency wallet app that works natively on both iOS and Android. The goal is a non-custodial solution where private keys stay on the device at all times, giving users full control of their funds without sacrificing ease of use. Core deliverables • Generate & import wallets (mnemonic/keystore), display balances, send and receive transactions • Clean, intuitive UI built in Swift/Kotlin or a cross-platform stack such as React Native or Flutter—your call, so long as performance and security are solid • Direct connection to a public node (Ethereum by default; I’m open to alternatives you recommend) with real-time transaction updates • QR scanning plus copy/paste for addresses, clear error ...

I’m putting together a lightweight, single-screen iOS showcase that cleanly demonstrates MVVM, Combine, and SwiftUI best practices. The app will fetch data from my REST endpoint, then present it in two distinct sections: • A horizontally swipable 1-on-1 card carousel. Every card contains only text, and I’d like a subtle fade as the user moves from one card to the next. • A vertically stacked FAQ where each question expands or collapses to reveal its answer—again, text only. The focus is on readable, well-structured code: clear view models, proper dependency injection, async networking, graceful error handling, and tight SwiftUI layout. If a small mock or preview layer helps illustrate the architecture, feel free to include it. The finished project should run...

I am re-branding an existing Linphone iOS build and need the entire colour palette swapped out for my own custom colours. Only the colour scheme is changing—icons, buttons, fonts, layout and functionality all stay exactly as they are. You’ll receive: • The current Linphone Xcode project (Swift/Objective-C mix). • A simple style guide with the new HEX/RGBA values. What I need you to do: • Replace every hard-coded or asset-catalog colour so the new palette drives the whole UI: headers, footers, call screens, settings, alerts—nothing should slip through. • Keep the project compiling cleanly in the latest Xcode and running on current iOS devices and simulators. • Return the updated project (or a clean git diff) plus a brief note on where...

The core of my Python-based karaoke app is already in place and running on the dedicated machine, but I need an extra pair of hands to get it fully ready. Right now the top priorities are layout tweaks and a round of bug fixing. On the bug side, you’ll be tackling a mix of incorrect functionality and some persistent UI glitches. For the layout, I need elements rearranged so the screen flows better and the colour scheme refreshed to match the venue’s branding. Everything lives in a private Git repository, and you’ll test remotely through RustDesk on the karaoke hardware that’s already set up, so you can see exactly how each change behaves on the real system. I want someone who can dive in immediately, push clean commits, and keep momentum going—there’...

I’m ready to turn my idea into a fully-functional mobile application that runs seamlessly on both iOS and Android. I have the concept defined and now need an experienced developer (or small team) who can guide the technical choices, design the user experience, code the app, and prepare it for release in both stores. From laying out the architecture through to final deployment, I’m looking for someone who can handle the entire lifecycle, communicate progress clearly, and suggest best-practice solutions along the way. If you have a portfolio of live cross-platform apps and can point to measurable results—downloads, ratings, performance stats—that will help me gauge fit quickly. Please tell me which framework or tech stack you recommend (Swift / Kotlin, Flutter, ...

I’m building a practical, no-frills utility app that must feel identical on iOS and Android. The project is green-field, so you’ll be responsible for architecture, clean code, and publishing-ready builds. Core scope • Platforms: the app has to ship on both iOS and Android from a single codebase. • Nature: it’s a straightforward Utility app—nothing flashy, but it must be rock solid and fast. • Must-have features: – Offline functionality so key screens and actions work without a connection. – Secure user authentication (email / social sign-in is fine, as long as it’s safe). – Silent data synchronization that catches up automatically when the device reconnects. I’m open to Flutter, React Native, or a wel...

Project: iOS & Android Keyboard App Integrated with GoHighLevel API We are looking for an experienced mobile app developer (or small team) to build a custom iOS and Android keyboard application that allows users to quickly share marketing content inside messaging apps (SMS, WhatsApp, Messenger, Instagram, etc.).

I need an experienced iOS developer to give my live Apple app a focused refresh. The main issue is straightforward: after users pay for one of our three subscription tiers—monthly, quarterly, or yearly—the entitlement doesn’t unlock. Payments clear, but StoreKit never flips the switch. Your first task will be to trace that activation path, correct whatever is blocking it, and confirm the fix in both sandbox and production environments. Once the subscription flow is solid, I’d like a light round of cosmetic tweaks on the sign-up screens so everything renders crisply on the latest iPhone and iPad sizes. Nothing major—just small UI polish to keep the experience on-brand. Deliverables • Reliable activation for all three subscription packages • Test...
