I’m ready to acquire a mobile app you’ve already built but never fully launched. My budget is modest (under $100), so I’m specifically after a side-project or leftover client build that’s just gathering dust and could be earning instead. Here’s what I need from you: • Complete source code and build files • Written transfer of full commercial rights • An existing or easily added paywall/subscription screen so I can switch on recurring revenue fast If you have something that fits, send the APK or TestFlight link, a short rundown of what the app does, the stack you used, any current in-app purchase hooks, and a link to past work that shows you’ve shipped solid mobile products before. I can move quickly—looking to close ASAP—and I’m also open to a longer-term partnership where you keep improving the code while I focus on marketing and growth, splitting profits down the line. Let me know your preference when you respond, along with your asking price for an outright sale. Excited to see what you’ve built!

Hi, This project focuses on acquiring a ready-to-launch mobile app with a functional paywall for recurring revenue. The main engineering risk lies in ensuring the paywall and subscription system integrate seamlessly and can be activated quickly without breaking existing app functionality. I approach systems by first validating the completeness of source code and build files, then assessing the existing in-app purchase hooks and paywall implementation for readiness and compliance with platform standards. Given the budget and quick close intent, the architecture must be straightforward with clear commercial rights transfer and minimal technical debt. I recommend separating the paywall logic from core app features to facilitate easy activation and future improvements. Systems like this require careful handling of subscription states and user entitlements to avoid revenue leakage. I can review the app’s current paywall integration and provide a technical assessment or outline a plan for a clean transfer. Thanks, Hercules

Hello, I hope this message finds you well. I am interested in acquiring a mobile app that you have developed but not yet launched. My focus is on finding a side-project or a client build that has the potential to generate revenue. I am specifically looking for complete source code, transfer of commercial rights, and the presence of a paywall/subscription feature for quick monetization. If you have an app that aligns with these requirements, please share the APK or TestFlight link, a brief overview of its functionality, the technology stack used, current in-app purchase mechanisms, and examples of your previous mobile projects. I am prepared to move swiftly and finalize the acquisition promptly. Additionally, I am open to discussing a long-term partnership where you continue enhancing the code while I handle marketing and growth responsibilities, with profits shared accordingly. I am eager to review your offerings and explore potential collaboration opportunities. Best regards, Muhammad Anas Khan

Hi, Your objective to quickly monetize existing mobile apps by adding paywalls aligns with the need for a clear, maintainable codebase and smooth integration of subscription features. The main technical risk is ensuring the paywall and subscription logic can be cleanly integrated or enabled without destabilizing the existing app functionality. While my primary experience is in backend AI systems rather than mobile app development, I have led projects requiring robust API design and scalable system architecture, which are relevant for subscription management and rights transfer. For example, in the DocIntel AI platform, I designed modular backend services that separate ingestion, processing, and retrieval layers to maintain system reliability and scalability. I typically design systems with clear separation between UI and backend logic, which helps in adding features like paywalls incrementally. Validating the subscription flow early would be critical to avoid revenue interruptions or user experience issues. Reliability measures such as fallback routes for subscription verification and idempotent payment handling reduce failure impact and simplify maintenance. I can start by outlining how to architect the subscription integration and review the existing app's codebase for smooth feature addition. Thanks, Clifton

Hi there, I think you are trying to acquire a ready-made mobile app that can be launched quickly and monetized through subscriptions, rather than funding a full app from scratch. I can help you identify a suitable existing app, review its architecture and current functionality, and prepare the source/build files for a clean commercial handover. I’ll also verify the subscription/paywall implementation and explain exactly what is ready, what needs configuration, and what can be launched immediately. I can provide a concise overview of the app concept, technology stack, current IAP/subscription setup, and available build/test version before any transfer. Full rights, source code, and documentation can be clearly defined as part of the handover. Looking forward to work with you. Thanks

Hi there, I can see exactly what you’re after: a ready-to-transfer app that already has the hard part done, so you can switch on revenue without rebuilding from scratch. I’ve worked with PHP, MySQL, APIs, payment flows, and app-backed web systems, and I can review what you have, confirm the source/build transfer, and help tighten the paywall or subscription flow if needed. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If the app is a fit, I can move quickly on the transfer checklist, commercial rights, and any setup needed for recurring billing. Is the subscription/paywall already connected to App Store or Google Play billing, or does it need to be added? Please send the APK/TestFlight link, current stack, and whether subscriptions are already wired to App Store/Google Play or need adding. Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

Hello, the key point here is not just buying an unused app — it is finding a codebase that can be transferred cleanly, launched quickly, and has a realistic path to adding subscriptions. I can help review the app structure, source code, build setup and existing payment hooks before transfer. I’d pay attention to ownership transfer, dependency issues and whether the current architecture can support a paywall without rewriting the core features. I’ve worked with mobile app development and API-based systems where clean handover and future updates mattered. Do you already have a preferred app category, or are you open to reviewing different types of side projects?

Hello, As a result of a detailed review of your project requirements, I fully understand that you are looking to acquire an existing mobile app rather than fund a new development project, with complete source code, commercial rights, and a clear path to subscription revenue. I can provide the complete source/build files and, provided all included assets and dependencies are transferable, written assignment of my commercial rights to the project. In my opinion, the quickest route is to verify the existing build first, review third-party dependencies/licensing, and then add or configure the subscription/paywall flow before store publication. My asking price for an outright sale is 300. I’m also open to continuing development after transfer, although I would prefer to keep the initial acquisition and any future revenue-sharing arrangement as separate agreements. I can provide the APK/TestFlight build and further technical details for review. Best regards, Carlos.
