I want to launch a cross-platform application that blends real-time messaging with a Facebook-like social feed. The core of the project is a single code-base experience—iOS, Android, and a responsive web app—where users can text, share media, and post updates without feeling they have stepped into three different products. Core experience • Rich one-to-one and group chats, complete with voice and video calling • A scrolling news feed for posts, photos, and short videos • Push notifications that stay in sync across devices Scope of work You will architect the full stack, build the native or hybrid front ends, wire up voice/video (WebRTC or similar), create an intuitive news-feed UI, and deliver a lightweight admin dashboard so I can manage users and report...

I need assistance uploading my completed and tested app to the Apple App Store. I have access to my Apple Developer account, but need help with some parts of creating the app's listing (app name, description, screenshots, etc.). I have the .ipa file but I can't figure out how to upload it to my apple developer account. Ideal Skills and Experience: - Experience with Apple App Store uploads - Familiarity with Apple Developer account management - Knowledge of creating app listings

Project For @shawanay I already have the full Figma layout and interaction flow ready; what I now need is the working application for both iOS and Android that mirrors that design exactly. The core purpose of the product is audio, and the single must-have feature is smooth, reliable audio streaming. Please use the design we agreed on as the unambiguous source of truth for all screens, colours, icons and transitions. Feel free to suggest minor UI tweaks if you spot obvious usability improvements, but any change has to be cleared with me first so the final build stays aligned with the mock-ups. Deliverables • Pixel-perfect iOS and Android builds (latest stable versions of Xcode and Android Studio) • Source code pushed to the shared repo with clear commit messages • ...

Apple rejected my latest iOS build under guideline 3.1.1 because the app still routes subscription payments through Cashfree. All paid plans – which unlock both exclusive content and extra functionality – must be available via Apple’s In-App Purchase, yet my earlier attempt to integrate StoreKit and migrate existing users ran into technical and review-blocking issues. I’m looking for someone who can step in, replace or supplement the current Cashfree flow with a fully compliant IAP solution, handle receipt validation, restore purchases, and guide me through the resubmission so the app finally gets approved. An ideal outcome is a clean Xcode project, a sandbox-tested IAP implementation for the current subscription tiers, and clear instructions for future plan chan...

I’m building a new social platform that lets users share photos and short videos while chatting in real time. The scope covers complete development for both iOS and Android, including design, backend, and production deployment. Core experience • Seamless photo/video capture, upload, and feed browsing • One-to-one and group messaging with push notifications • Account creation via email, phone, or social sign-in • Profiles, likes/reactions, basic content moderation, and media storage in the cloud • End-to-end encryption for private chats I’m open to React Native, Flutter, or separate native builds; recommend the stack you feel gives the best performance and maintainability. Please submit a detailed project proposal outlining your planned archi...

I’m ready to launch a full-featured e-commerce application that runs smoothly on both iOS and Android from day one. The goal is an intuitive, reliable mobile shop where customers can browse, add to cart, and check out without friction. Scope • User onboarding: secure account creation, social or email login, and password recovery. • Product discovery: searchable, filterable catalog that handles thousands of SKUs and displays rich media. • Seamless purchasing: persistent cart, multiple payment gateways, order confirmation, and basic order-tracking screen. You’re welcome to propose the stack—whether that’s Flutter, React Native, native Swift/Kotlin, or another robust cross-platform solution—as long as performance, scalability, and App Sto...

I have a live Flutter application on both iOS and Android that now needs a comprehensive refresh. We need to work things like bugs, ui updates and new features You must be expert in flutter and be able to implement. We will do small projects and publish updates Part 1. Review and debug Part 2. Prepare and publish app on IOS store Part 3. Prepare and implement completely new interface, and implement new features *** This post is for Part 1 only ***

I need a complete iOS application that blends real-time voice communication with modern chat functions. At its core the app must handle one-to-one voice calls and one to more voice call, fast text messages, and flexible group chats, but I also want it to feel like a social audio space where people can drop into public rooms, discover new friends locally or worldwide, and then move into private rooms when they wish.(also public chatting room with many people at Same time) Beyond chat itself, the product has to support a live gifting system tied to an in-app wallet: users buy coins through Apple’s payment flow, send virtual gifts during conversations, and track their personal balance from a simple dashboard. Basic login/logout is enough for the first release, yet the code should be or...

I need an iOS-only marketplace app where anyone can put an item up for sale, schedule the exact time they want the auction to begin, and then watch a lively 3D, slightly exaggerated auctioneer run the bids in real time. Sellers must be able to upload photos, write their own descriptions, and set the starting bid price before locking in a slot on the calendar. During the live session, bidders enter a virtual “room.” Whether three people show up or three hundred, the animated host should keep pace, increment bids, announce the winner, and trigger payment confirmation once the hammer drops. I picture a stylized, cartoon-like 3D character—think fun, friendly, and upbeat rather than hyper-realistic—rendered smoothly on modern iPhones. Audio call-outs (“Going onc...

I’m looking for several testers to spend about ten minutes inside a pre-release iOS app and report what they see. Requirements • You use an iPhone 13 or newer running iOS 14. • You’re comfortable taking clear, full-screen screenshots. What you’ll do 1. I’ll send a short task list. 2. Work through it, capturing each key screen. 3. Add a brief comment wherever something feels confusing, slow, or broken. Deliverables • 8–10 labeled screenshots that trace the flow I provide. • A concise summary (3–5 sentences) of your overall impression and any issues. That’s it—quick, simple, and perfect for anyone who likes trying new apps before they hit the store.

My planning app is already coded and running, but the user interface still feels rough around the edges. I need an experienced iOS developer who can give the UI a final professional sheen, run the necessary tests in Xcode/TestFlight, and then take the build all the way through App Store Connect until it is submitted for review. The core functionality is locked in, so your focus will be on layout consistency, smooth transitions, font and colour harmony, and generally making the screens look like they belong on a top–tier productivity app. Once the polish is in place, I’d like you to prepare the release archive, create the screenshots, fill in the metadata, and press the submit button. Deliverables • Refined Xcode project with updated UI assets and layout tweaks •...

I need a full-stack mobile developer to build an app that runs smoothly on both iOS and Android. The core flow is simple: a user logs in, records their voice, receives a near-error-free transcript, and then sees AI-generated feedback on that recording. Key functionality • Secure email / social login with token refresh • High-quality voice recording (no video or screen capture) stored locally first, then uploaded in the background • Server-side transcription that targets minimal errors—think the accuracy of best-in-class speech-to-text engines, not a basic word dump • An AI analysis module that scores clarity, pace, filler-word usage and returns actionable tips in real time • A clean history screen where users can replay audio, read transcripts, and...

Hi I will share the details with the shortlisted candidates. thanks

I need a single orchestration layer that can process Visa, Mastercard and American Express transactions for both my web checkout and native mobile apps. The flow must be protected with strong data encryption end-to-end and handle multiple currencies because our customers buy from several regions. Here’s what I am after: • A self-hosted or cloud-deployable gateway that exposes clean REST/JSON endpoints for authorise, capture, refund and void operations. • Built-in tokenisation so no raw card data ever touches my front-end. • Configurable routing logic (primary and fallback acquirers). • Detailed, exportable logs plus webhooks for real-time transaction updates. • Full technical documentation and a Postman collection so my team can plug it straight int...

I’m looking for a fully-featured Clash Royale private server based on version 2.0.4 (or the closest stable version you can reliably maintain). The objective is to deliver the same gameplay experience players had on Supercell’s official servers—just without in-app purchases—while supporting every iPhone and iPad from older devices like the iPhone 4s and iPad 2 on iOS 6 all the way up to the latest iOS versions. Core Requirements Multiplayer must be smooth and stable, capable of handling several thousand concurrent players. Please recommend a hosting setup you trust for this scale. All in-game systems should function exactly as expected (card upgrades, chests, clans, spectating, etc.), with only in-app purchases disabled. The game must install and run properly across...
