    My iOS app is code-complete, tested, and already aligned with every current App Store guideline; what I lack is an active Apple Developer account to submit it under. I will supply the signed IPA, screenshots, and description copy. You would sign in to your account, walk the build through App Store Connect, and keep me updated until Apple approves the release. Besides the actual upload, I’d like a bit of extra help so the launch goes smoothly: • Bug fixing: if Apple flags anything or a last-minute crash sneaks in, please patch and resubmit. • App promotion setup: polish keywords, craft the short/long description, and arrange the screenshots so the listing looks professional. • Analytics integration: wire Firebase (or a similar SDK we agree on) into the final build...

    Rebuild Source for Mobile App
    5 days left

    I released a consumer-facing app on both iOS and Android some time ago but, unfortunately, the original source code is no longer available. All I can provide today is the signed iOS IPA. I need someone who can either decompile that binary to recover as much logic /UI as possible or, if that proves impractical, rewrite the application so that it behaves exactly the same on both platforms. Core behaviour to replicate • Secure user authentication (current flow uses email + password). • Push notifications that mirror the existing timing and payload structure. What I will supply – The live IPA, screenshots of every screen, and a short video walkthrough so you can observe each interaction path. – Existing branding assets, copy and any server-side API documentation...

    I want to launch an iOS-only app that lets small “squads” of friends or co-workers set goals together and hold one another accountable. The core flow is simple: users create or join a squad, set individual or shared goals with clear deadlines, track their day-to-day progress, and nudge one another with in-app reminders when someone falls behind. Key functions I need built in: • Goal creation with target dates and optional subtasks • Visual progress tracking (percent complete, streaks, graphs) • Private squad spaces where members can see each other’s progress in real time • Peer-to-peer reminders a member can fire off to another member inside the same squad • Secure email-and-password sign-up and sign-in Everything should feel lightweight...

    I’m looking to license or purchase a fully-functional parental control app that already runs on both Android and iOS. The build must come ready with these core capabilities: • Screen time management that lets parents set daily limits and schedules • Robust content filtering to block age-inappropriate websites, apps, and search terms • Location tracking with real-time map view and geo-fenced alerting • Screenshare (or equivalent remote viewing) so parents can see what’s on the child’s device • Daily activity reports that summarise usage in an easy-to-read dashboard An existing, battle-tested codebase is essential; I’m not interested in commissioning a brand-new build from scratch. I’ll need: • Demo access or video walkth...

    I’m looking for an experienced iOS developer (or team) to create a real-money, arcade-style casino app ( Reference triumph arcade on the app store )that pays out cash rewards. Players deposit through standard credit or debit cards, pay a set entry fee per round, and can win a maximum of 3× their stake. The core loop should feel fast and fun like classic arcade machines rather than traditional slots or cards. Scope of work The job covers everything required to launch on the App Store: game mechanics, secure payment flow, player account system, basic wallet, and the rules engine that enforces the 3× payout cap. A clean, modern UI, smooth animations, and App Store-compliant age gating are essential. I’m open to your preferred frameworks (Unity, Swift + SpriteKit, et...

    I need an iOS application that can predict the next rounds of the 1win Lucky Jet game in real time. The app’s single, non-negotiable goal is speed: the prediction engine must process incoming game data fast enough to give users a genuine advantage before each round starts.

    I’m ready to turn a new app concept into a polished product and I’m looking for a developer who can guide the whole build— from setting up the architecture to publishing in the stores. The core brief is straightforward: • The app’s topic is still open; I’ll share final wireframes and user stories once we connect. • Three headline features will drive the first release. I have rough notes that currently map to standard staples such as secure sign-in, real-time alerts, and optional monetisation hooks, but I’m happy to refine these together so they fit the chosen tech stack and platform guidelines. • I haven’t locked myself to iOS, Android, or a cross-platform solution yet.

    My iPhone photos and videos were deleted by mistake and I must get them back. Unfortunately, I never kept an iCloud or iTunes/Finder backup, and although I have used the phone a little since the deletion, it has been only minimal. I can work from a Mac for any software-based recovery steps you provide or supervise. Here’s what I need from you: 1. A proven method—software-based or command-line—that can scan the iPhone’s internal storage directly and restore the lost images and clips without further overwriting data. 2. Clear, step-by-step guidance (live screen-share or well-documented instructions) so I can follow along on my Mac in real time. 3. Delivery of the recovered files in their original quality plus a brief validation that nothing is corrupted. 4. A short ...

    An iOS app I own is live in the Apple App Store, yet the entire original project is missing—no repository access, no local backups, nothing at all. What I still hold is the production build that Apple distributes, plus my own App Store Connect credentials. The goal is to retrieve the app’s source code, or at least rebuild a functionally identical Xcode project that I can maintain going forward. Only the source code matters; all assets and configuration files are already in my possession through the binary and App Store metadata. Because there is zero existing codebase to pull from, the work will most likely involve decompiling and reverse-engineering the published binary. Familiarity with tools such as Hopper, Ghidra, IDA, or similar Objective-C/Swift decompilers will be ...

    I need a complete mobile app that runs smoothly on both iOS and Android and showcases advanced facial-recognition capabilities.

The interface should feel modern and sleek with clean typography, subtle animations and dark-mode support.

I do not collect or track any user data, so the issue lies in the way my privacy settings are declared.
