I need a complete mobile application that lets users earn cash or credits simply by watching video and display ads. The core flow is straightforward: a user launches the app, selects an available ad, watches it to completion, and immediately receives the pre-defined reward in their in-app wallet or balance display. The build must cover both the user-facing front end and the server logic that tracks views, validates completions, and prevents fraud. Ad-network integration is central to the project, so experience with Google AdMob, Unity Ads, or similar SDKs is essential. I also expect a lightweight account system so users can sign up quickly—email, phone, or a social login option is fine—as long as each viewer can be uniquely identified. Because real money (or gift-card equivalents) is involved, accuracy in event logging, secure payout handling, and a clean audit trail inside an admin console are non-negotiable. The admin console should let me set reward rates, view aggregate statistics, and trigger manual or automated payouts via PayPal, Stripe, or direct bank transfer. Deliverables: • Fully functional Android (and ideally iOS) app, ready for store submission • Backend with APIs for ad completion tracking, user management, and payout processing • Simple admin panel for rewards configuration and analytics • Source code, build instructions, and minimal documentation for future maintenance Acceptance criteria include 100 % ad-view tracking accuracy in test mode, successful payout processing in sandbox, and app store approval readiness. Feel free to recommend additional monetisation or referral features if they enhance retention without distracting from the core watch-and-earn model.

Hello How are you, I can build a secure watch and earn mobile app where users watch ads to completion and instantly receive rewards with accurate tracking and fraud protection built into the core system. I will develop Android and iOS apps with a simple user flow for selecting ads watching them fully and updating wallet balance in real time, integrated with ad networks like AdMob or Unity Ads for reliable delivery and monetization. The backend will handle ad completion validation user authentication reward calculations and payout processing, along with an admin panel to manage reward rates monitor analytics and trigger payouts via PayPal Stripe or bank transfer. The system will include strong event tracking anti fraud checks and a clean audit trail to ensure accuracy in rewards and payments while keeping the app ready for store approval. I have worked on similar reward based and ad driven applications where tracking accuracy secure payouts and scalability were critical for real world usage. I have one quick thing to ask before we start do you want rewards to be fixed per ad type or dynamically adjusted based on ad network revenue and user engagement? Please check out my profile to review my past projects and portfolio. https://www.freelancer.com/u/Hammadhassan21 I can start immediately and deliver a production ready MVP with reliable tracking and payout flow. Ping me on chat to discuss all the details and move forward. Thanks.

Hi - Watch-and-earn apps don’t drift because rewarded ads are hard, they drift when ad completion, wallet credit, fraud checks, and payout status do not share one trusted server record. A real flow should be: user signs in - selects an available rewarded ad - SDK confirms completion - backend validates the event - duplicate checks run - wallet balance updates - admin sees the earning log - payout is reviewed or processed through PayPal, Stripe, or bank transfer. This looks straightforward, but it gets inconsistent when the app credits users directly from client-side callbacks. Spoofed or repeated ad events can lead to unexpected results in real use, so I handle it by using server-side validation, idempotent reward records, and payout audit logs. The part to get right early is the reward ledger, because it affects usability, accuracy, fraud control, and store approval readiness.

Hey, I will deliver the Android and iOS app, backend APIs, and admin panel — covering ad-view tracking, wallet management, and payout processing via PayPal and Stripe. For fraud prevention, I will implement server-side ad completion validation using signed callbacks from AdMob's SSV (server-side verification). This ensures reward credits are only issued when Google confirms a genuine view — blocking emulator farms, replay attacks, and modified clients before they ever hit the wallet balance. Questions: 1) Do you have a preference for the tech stack — React Native or Flutter for the app, and Node.js or Python for the backend? 2) What payout thresholds and frequency do you envision — daily, weekly, or user-triggered once a minimum balance is reached? Looking forward to discussing further. Best regards, Kamran

Hi there, I have read your project requirement carefully. You need a complete “watch-and-earn” mobile application with Android (and ideally iOS), including ad network integration, reward tracking, secure backend logic, user accounts, and an admin panel for payouts and analytics. We can build this using Flutter for cross-platform apps and a secure backend (Node.js with PostgreSQL). The app will integrate with ad networks like AdMob/Unity Ads, track ad completion events accurately, manage user wallets, and handle secure payouts (PayPal/Stripe sandbox to live). The backend will include fraud prevention mechanisms (device fingerprinting, duplicate detection, rate limiting), and the admin panel will provide full control over rewards, analytics, and payout processing. The system will be designed to meet app store compliance and scalability requirements. A few questions to proceed further: ============================= Which ad networks do you prefer (AdMob, Unity Ads, or multiple)? What type of rewards system do you want (cash, gift cards, points conversion)? Do you need a referral/bonus system included in the MVP? Which payout methods should be prioritized (PayPal, bank transfer, Stripe)? Best Regards, Srashtasoft Team

Hi I can build a watch-and-earn mobile app with user accounts, ad-network integration, wallet balance tracking, backend validation, payout handling, and an admin console. The main technical challenge is making sure ad completions are tracked accurately while preventing fake views, duplicate rewards, device abuse, and payout-related fraud. I would recommend Flutter or React Native for Android/iOS, with a Node.js or Laravel backend, PostgreSQL for wallet and audit records, and AdMob, Unity Ads, or another approved ad SDK for rewarded ads. The backend would validate ad completion callbacks, record every reward event, update user balances securely, and maintain a clean transaction ledger for admin review. The admin panel would allow reward-rate configuration, user and payout management, analytics, fraud checks, and sandbox testing for PayPal, Stripe, or other payout methods. I can also structure the app for store submission readiness, including clean onboarding, reward rules, referral options, build instructions, and maintainable source code. Thanks, Hercules

Building an app where users earn rewards by watching ads requires precise tracking and strong fraud prevention, and I’ve done this before helping a client integrate Unity Ads with a secure wallet system. My approach begins with a simple sign-up flow to ensure unique users, then a backend that logs each ad view with accuracy and flags suspicious activity. I’ll integrate your chosen ad networks (Google AdMob, Unity Ads, or others) ensuring reliable callbacks for completion events. For payouts, I suggest sandbox-testing both PayPal and Stripe APIs upfront to confirm smooth, auditable transactions. The admin panel will let you adjust rewards, monitor stats in real time, and trigger payouts manually or via automation. A quick question: Do you prefer rewards to be immediately spendable in-app credits, or redeemable only after a threshold? Also, should the admin console support multi-admin roles or just a single user? Based on similar projects, this can be done efficiently and ready for app store submission. I’m ready to start building a secure, reliable, and easy-to-use system that fits your vision.

Dear Hiring Manager, I am ready to start today and can develop your complete “watch-and-earn” mobile application with a secure backend, ad-network integration, and fraud-resistant reward system. I have experience building full-stack mobile apps with real-time event tracking, wallet systems, and API-driven architectures. I understand this project requires strict accuracy in ad completion tracking, secure reward distribution, and a scalable backend to prevent abuse while maintaining smooth user experience. Approach: I will build a cross-platform mobile application (Flutter or native Android/iOS depending on preference) integrated with AdMob/Unity Ads SDK for video and display ads. Each ad completion event will be securely validated via server-side verification APIs to ensure users only receive rewards after legitimate completions. The backend (Node.js or Python) will manage user accounts, wallets, reward logic, and fraud detection (IP/device/session checks, rate limiting, and event validation). An admin panel will be created for reward configuration, analytics, and payout management. Payout processing will integrate Stripe/PayPal sandbox first, with secure audit logging for every transaction. Clarification Points: Preferred stack: Flutter, React Native, or native Android/iOS? Which ad networks will you prioritize (AdMob, Unity Ads, both)? Payout method priority (PayPal, Stripe, bank transfer)? Expected daily user volume and ad impressions? Best Regards
