    I’m launching a new social networking experience and need a polished mobile application that runs smoothly on both iOS and Android. The core idea is to let users create profiles, connect with friends, share posts (text, images, short videos), and chat in real time with push-notification support, all wrapped in a modern, intuitive interface. I already have the high-level concept sketched out but welcome your input on refining user flows, selecting the most suitable tech stack (React Native, Flutter, Swift/Kotlin with a shared backend—whatever you feel is best), and integrating standard social features such as secure sign-up/login, a customizable feed, basic privacy controls, and in-app reporting.

    I want to bring a new social networking experience to life on both iOS and Android, and I’m looking for a developer who can take the project from first sketch to App Store and Google Play release.

Here’s how I picture the collaboration: you’ll handle native or cross-platform code (Swift/Objective-C, Kotlin/Java, or a solid framework such as Flutter or React Native if it suits the build), integrate a secure backend with scalable authentication and cloud storage, and guide me through testing and store submission.

    I have a Base44 web app currently uploaded to TestFlight using Despia as a web wrapper. I want an iOS developer experienced with Capacitor to convert or repackage the app into a more native-feeling iOS app. The goal is not a full rebuild yet, but to improve the iOS experience with native navigation, splash screen, loading states, push notifications, haptics, camera/image upload, safe-area spacing, keyboard behavior, and App Store-ready polish. Please review the current TestFlight app and advise what can be improved using Capacitor versus what would require a full native/Flutter rebuild.

    I’m stuck at the very first hurdle with Unreal Engine 5.6.1 on my Mac. Every attempt to install ends in failure, and the installer throws Xcode-related errors even though the newest version of Xcode is already on the machine. I need someone who really knows the Mac tool-chain for Unreal—Xcode, command-line tools, possible Rosetta quirks, code signing, the lot—to jump in, diagnose what’s tripping the installer, and get the engine to launch cleanly. Happy to share logs, run Terminal commands, or screen-share so you can poke around the system directly. Deliverables: • Identify the exact cause of the Xcode errors • Apply or guide me through the fix (remote session is fine) • Verify that Unreal Engine 5.6.1 opens and creates a blank project without...

    I’m building a clean, lightweight mobile app that lets users post their own short poems and browse work shared by others. The heart of the project is a smooth poetry-sharing flow with a built-in rating system so readers can quickly show appreciation and high-quality pieces float to the top. Key screens will include a feed of recent poems, an upload page (text only for this first release), a detail view that displays the poem and its current rating, and a simple profile section that lists everything the user has shared. I also need a small moderator console—web-based is fine—where poems can be removed or featured. Design can stay minimal: crisp typography, dark-mode friendly, and intuitive bottom navigation. I’m happy with either native stacks (Swift/Kotlin) or a c...

    We are ready to bring a full-featured, Uber-style taxi service to life and need a developer (or small team) who can take the project from concept to launch on both iOS and Android. The passenger app must include frictionless user registration and secure login, real-time ride booking with live vehicle tracking on a map, plus in-app payment integration that supports major cards and digital wallets. In parallel, we also require a separate driver app. It should mirror the passenger experience where appropriate, receiving ride requests, turn-by-turn navigation, earnings summaries, and status toggles, while keeping the codebase as maintainable as possible.

    My Flutter application is already complete and thoroughly tested; the last step is getting it onto my personal iPhone and eventually into TestFlight. I have not yet joined the Apple Developer Program, so I need guided help enrolling, choosing the right plan, and linking everything to Xcode. Once the account is active I’m unsure about certificates and provisioning profiles, so I’ll rely on you to generate and configure whatever is required (development, distribution, or automatic signing), connect them to my Flutter project, and produce a working .ipa. You may use the normal toolchain—Flutter, Xcode, and, if it speeds things up, Fastlane—to handle builds, code-signing, and TestFlight upload.

    We are developing an exclusive iOS application built with Flutter. The core feature revolves around displaying 3D objects (spheres) in real space based on specific geographic coordinates (Latitude & Longitude). Currently, the app is facing a critical issue: when using ⁠ARWorldTrackingConfiguration⁠, the 3D objects spawn near the user or shift their positions relative to the user's movement. They do not stay fixed to their assigned real-world GPS coordinates, and they reset/spawn relative to the camera every time the app is reopened. Required Tasks: 1. Refactor the AR implementation using ⁠arkit_plugin⁠ (or an equivalent native iOS wrapper for Flutter). 2. Implement a mathematical approach (e.g., Haversine Formula) to calculate the distance and bearing between the user's curre...
