Dear Employer, We have already built and worked on similar Flutter applications, including gym, fitness, wellness, and subscription-based apps, so we understand the iOS adaptation and App Store publishing process well. We can take your existing Android Flutter app, connect it with the same backend, handle all iOS-specific configuration, TestFlight, certificates/signing, App Store submission, and approval. We’ll work within your existing Codex architecture rather than rebuilding what already works. We’ll also publish everything through your Apple Developer account, ensuring you retain full ownership and can update the app independently in the future. We can provide ongoing maintenance and support for the full one-year period. Best Regards, Sumay Infotech

Hi there, I understand you already have the Flutter app running on Android and now need it properly adapted, tested, and published for iOS. We have the MacBook and Apple App Store experience needed for the full process. We’ll use your existing backend and Flutter code, keep everything connected with the current architecture, and set up the Apple Developer account so you keep full ownership and access. I’ve also gone through the issues you listed, including message search, video thumbnails and dates, online/offline status, settings toggles, private account follow notifications, saved reels, video zoom and saving, likes visibility, follow buttons, notification navigation, and the new Instagram-style share flow. I can also handle the story media editor and redesign the music page with a more premium Spotify-style layout, including optional cover images for uploaded songs. Once the iOS version is ready, we’ll test it properly on real iPhones, handle certificates and App Store submission, fix any issues during review, and continue maintaining the app for the full one-year period. Regards , Khalid,

Hi, there. "IOS GYM APP DEVELOPMENT" - you need the app built, published to the App Store, and maintained through future updates rather than stopping at the first build. I’d use Flutter where it fits the existing requirements, keeping the iOS experience responsive and the codebase structured for ongoing maintenance. I’d handle the core gym workflows, API integration where required, testing on real iOS devices, App Store build configuration, and release preparation. I’d also keep the GitHub repository organized so future features and fixes can be developed without making the project difficult to maintain. Can you share the current app requirements or existing repository so I can understand what needs to be built first? Looking forward to working with you.

Hello there , I can take your existing Flutter Android app and adapt, configure, test, and publish it for iOS, while reusing your existing backend and architecture without rebuilding the system. I have experience with Flutter iOS builds, Xcode configuration, Apple Developer/App Store Connect, certificates, provisioning, TestFlight, App Store submission, review fixes, and production releases. I’ll ensure the iOS version integrates seamlessly with your existing backend and follows Apple’s requirements. I’ll handle: * Flutter Android → iOS adaptation * iOS/Xcode configuration and build setup * Existing backend/API integration * iPhone/iPad compatibility testing as required * TestFlight setup and UAT * App Store submission and approval support * Apple certificates, provisioning & signing * Complete Apple Developer account access/ownership for you * One-year maintenance and release support * Full project/source-code handover I understand the requirement to work within your existing Codex-generated codebase and architecture, with no unnecessary backend rewrite or architectural changes. Key point: the Apple Developer account will remain under your ownership, and I’ll configure the project so you can publish future updates independently if required. I can start by reviewing the existing Flutter project and Android build, then prepare the iOS release pipeline and App Store submission. Let’s discuss the current codebase and Apple account setup. Thanks

Hi, I'm Denis, a full-stack developer with experience building and maintaining iOS applications. I've worked on similar projects focused on clean user experience, app lifecycle management, and ongoing maintenance. You're looking for someone to handle the full journey—building the gym app, managing App Store review, and maintaining it long-term. That's exactly what I do. My approach starts by understanding your core features: workout tracking, class scheduling, member profiles, progress analytics, or a combination? I'd then design scalable, maintainable architecture with clean code practices so future updates are straightforward. For publishing, I'll handle the entire App Store submission process—privacy policies, app icons, screenshots, and review guidelines. It requires attention to detail but is manageable once you know the process. On maintenance, I'll set up crash monitoring, manage updates, fix bugs, and implement feature requests. I'll also keep dependencies updated to prevent security issues. One important clarification: your backend infrastructure. If you need a server for user data, payments, or real-time features, we should plan that alongside the iOS app for seamless integration. I'm ready to start immediately. Let's discuss the details. Thanks, Denis.

Your Android Flutter app is already built, so the priority is adapting the existing project for iOS, validating it against the same backend, and getting it successfully through App Store submission without changing the existing architecture unnecessarily. I can handle the iOS build configuration, signing, provisioning, device testing, App Store preparation, submission, and post-launch maintenance. My strongest match is Flutter and cross-platform mobile development. I can work from the existing Flutter codebase and backend, identify iOS-specific configuration or dependency issues, verify API behavior on iPhone, configure the required Apple project/signing settings, and prepare the production build for App Store Connect. I’ll also ensure the Apple developer account remains under your ownership and that your team retains the required access for future updates. For the one-year maintenance period, I can handle iOS-specific build issues, dependency updates, App Store submissions, and compatibility fixes as needed while keeping the existing Android/backend architecture intact. Can you confirm whether the existing Flutter project is already building successfully on any Mac/iOS environment?

I have successfully published numerous apps on the Apple store and command access to multiple apple accounts. This ensures that even after my one-year maintenance term, you'll still have full control and efficient updating capabilities without requiring my involvement. Building products for scalability and long-term growth is one of my hallmarks as a freelancer. Your gym app is no exception. By leveraging my rich experience in building marketplace platforms, business management software, workflow automation solutions - all integrated with robust backend systems - I am adept at creating products that not only function flawlessly but also scale smoothly as user demands increase.

Hello, how is it going? I understand you need an iOS gym app built with Flutter, published to the App Store, and maintained with ongoing updates. The main technical challenge is making the app stable across iPhone devices while keeping the architecture clean enough for future fitness features and API integrations. I’d build the Flutter app with a scalable structure, GitHub-based version control, proper iOS signing and certificates, TestFlight testing, and App Store submission. I can also integrate OpenAI/Codex-assisted development where useful while keeping the production code reviewed and maintainable. For ongoing maintenance, I’d handle bug fixes, iOS compatibility updates, dependency updates, and future feature releases. Could you share the current app requirements or design so I can estimate the build and publishing work accurately? Looking forward to working with you.

A reliable gym app needs more than a build: it needs a clean release pipeline, App Store compliance, and maintainable updates after launch. I can take your Flutter/iOS app from repository review through implementation, QA, App Store submission, and ongoing maintenance. I’ll first assess the current code, screens, dependencies, signing setup, and any existing backend/API contracts, then fix or extend features with a modular structure and GitHub-based workflow. I’ll test on representative iPhone/iPad devices, verify navigation, state handling, network failures, permissions, performance, and release builds, and provide practical handover notes so future updates remain predictable. With 9+ years of software development experience across mobile and web applications, I’ll communicate progress clearly and keep changes reviewable rather than creating a fragile one-off build. Could you share the repository state, current Flutter/Xcode versions, target iOS versions, and the features already implemented? Do you already have an Apple Developer account, app listing, backend, and final design assets? I can begin with a focused audit and an initial release plan.
