    I already have an active Apple Developer account and an published iOS app. What I still need is the full Apple-side setup that lets Firebase send OTP codes to my users. Here’s the gap I’d like you to close: • Create or guide me through generating the correct APNs Auth Key and any required push-notification certificates in the Apple Developer portal. • Enable the proper entitlements in the existing App ID, then link the key to my Firebase project so Phone Auth can reach Apple devices. • Provide a quick walkthrough (screencap or short doc) so I can repeat the process for future bundle IDs. • A lightweight validation step—build runs in Xcode, the test device receives an OTP, and Firebase logs a successful verification. Everything is limited to...

    I’m looking for an experienced game modder to create a user-friendly DLL plugin for Middle-earth: Shadow of War (Definitive Edition, PC/Steam) that streamlines orc (Uruk) customization. The mod should integrate with ReaperAnon’s Middle Earth Mod Loader (free GitHub tool: ) for easy install (drop DLL to x64/plugins/). Current solutions like Cheat Engine tables (e.g., SeiKur0 : ) are powerful but too complex (pointer scans, manual IDs, glitches). I need a simple ImGui menu (F10 key) for in-game orc editing—hover/select in Army/Followers screen > edit/save. Key Goals: • Make orc army building fun: 1-click presets for epic hybrids (Balrog fire giants, Gondorian captains, Nazgûl wraiths, Sauron overlords). • Offline-safe (no servers detect). • Stable...

    I have an iPhone app that is already live on the App Store and fully functional on the backend; what’s missing is the fresh coat of paint my designer finalised in Figma. I need someone who can open those Figma files today, drop the new icons and fonts in place, adjust each layout exactly as shown, and push the refreshed build back to TestFlight—all within the next five days. The work is implementation-only: no new endpoints, no business-logic tweaks. Everything remains in portrait mode, so you won’t be juggling constraints for landscape. If you’re comfortable moving fast in Xcode, know your way around Auto Layout (or SwiftUI’s equivalent), and enjoy leveraging AI-powered IDE helpers to speed things up, you’ll feel right at home.

    We are seeking an experienced iOS developer to build an automated boat-race betting system. This project requires processing more than 5,000 vertically oriented smartphone screenshots, all following a consistent two-venue layout. Your primary responsibility will be implementing highly accurate OCR capable of extracting finishing orders, racer numbers, and box-order patterns such as 1-2-3 or 2-3-4. Using this extracted data, the system must automatically place bets even though no official API is available. To achieve this, you will need to implement reliable WebView-based automation or native UI automation to complete purchase flows. The system must also include Martingale-style money-management logic to adjust capital during operation. Security is essential, so credentials and in-app acti...

    I’m launching an e-riksha ride-hailing service and need a complete mobile application that runs smoothly on both iOS and Android. The user journey begins with phone-number registration and OTP verification, so that step must feel instant and secure. Core functionality I expect on day one: • Real-time GPS tracking that lets riders watch their riksha approach and gives drivers accurate turn-by-turn directions. • Seamless payment integration covering cards, UPI, and wallets so no ride ever stalls at checkout. • A driver rating & review module that captures feedback after every trip and shows average scores up front.

From refining the idea through UI design, coding, testing, and App Store submission, I need a developer who can own the entire lifecycle using Swift, Xcode, and the latest iOS SDKs. What I expect: • A clear plan outlining major milestones—from initial wireframes to TestFlight builds and final release. • Clean, well-documented code that follows Apple’s Human Interface Guidelines. • Ongoing communication so I can review progress and give timely feedback. • A final build that sails through App Store review without surprises. If you’ve recently shipped iOS apps, tell me about them, share links, and highlight any challenges you solved along the way. I’m esp...

    I have a complete Cordova project and all of the necessary Apple certificates and provisioning profiles. What I’m missing is a clean, signed iOS build. No new features, no plugin wrangling—just take the existing codebase, run the build on a macOS environment with the current Cordova CLI / Xcode toolchain, and hand back an IPA that’s ready for TestFlight or direct App Store submission. Deliverables • Signed IPA (built with my certificates & profiles) • Xcode archive or command-line steps so I can reproduce the build on my side That’s the full scope. If you routinely compile Cordova apps for iOS, this should be a fast, straightforward hand-off.

The core requirement is simple, reliable income tracking—no expense features, no web or desktop versions, just a clean mobile experience built specifically for iPhone and iPad. Here’s what I’m envisioning: • A quick-add screen where I can log income amounts, dates, categories, and notes in seconds. • A dashboard that summarizes daily, weekly, and monthly totals with a couple of basic charts. • Search and filter tools so I can pull up entries by date range or category. • iCloud or local device storage; I’m open to whichever is faster to implement while keeping my data private. • An export option to CSV so I can back everything up or a...

    I want a fully-functional calculator that looks and behaves exactly like a normal, basic calculator until I key in a secret passcode. At that moment the interface should slide (or otherwise transition smoothly) into a private gallery where I can import, play, and manage all of my personal videos. The build needs to run natively on both iOS and Android, so please rely on a shared codebase—Flutter or React Native are both fine, as long as you can meet App Store and Play Store guidelines. Security is crucial: once inside the hidden area, users must still authenticate with the same numeric password they used on the calculator screen. Fingerprint or Face ID support is optional for the first version; simple password protection done well is my priority. Visually, I’m after an...

    I want to launch a cross-platform video-editing app that leans heavily on artificial intelligence to help users apply striking special effects with minimal effort. The core of the product is three smart features: AI-driven video filters, intelligent audio clean-up and mixing, and real-time object recognition inside each frame so the effects feel aware of the scene rather than pasted on top. The finished build must run smoothly on both iOS and Android. I’m open to the underlying tech—Swift/Kotlin, Flutter or React Native—so long as the exported video quality matches modern social-media standards (1080p at 60 fps) and the processing time stays competitive with native editors.
