I’m ready to release a straightforward offer-wall earning application on Android and need someone who has already built this kind of system before. The app’s core loop is simple: users complete surveys, watch ads, or make small in-app purchases and are rewarded with points that are stored against their profile. What I need built • Rewards points system that instantly credits points for three earning channels—completed surveys, rewarded ads, and verified in-app purchases—and shows the live balance on every screen. • User profile management with secure sign-in (e-mail, Google, or similar), avatar, and a running history of earned points. All data must sync to the cloud so users keep their balance if they reinstall. Preferred stack Native Android (Android Studio). Kotlin is ideal, Java is fine. You can propose Firebase, Supabase, or another lightweight backend as long as authentication, realtime updates, and basic analytics are covered. Deliverables 1. Full, well-commented source code and Android Studio project 2. Debug and release APKs ready for Play Store testing 3. Brief setup guide so I can swap ad networks or survey providers later 4. One post-handover bug-fix cycle Acceptance criteria • Completing at least one survey, one ad view, and one in-app purchase each adds the correct number of points without restarting the app. • Profile and points persist after logout, app restart, and reinstall. • The app passes Play Console pre-launch review with no critical crashes. If you have a live or past rewards app, a quick screenshot or store link will move you to the top of the list.

Hi there, I have read your project requirement. You need an Android offer-wall earning application with a real-time rewards system integrating surveys, rewarded ads, and in-app purchases, along with secure user profiles and persistent cloud-based data. We will develop a robust Android app using Kotlin with a scalable backend (Firebase or similar) to handle authentication, real-time point updates, and data sync. The system will ensure instant reward crediting for all earning channels, maintain accurate user balances across sessions, and provide a clean UI with profile history tracking. We will also structure the app so ad networks and survey providers can be easily swapped in the future. Before proceeding, I have a few questions: ================================== Which survey providers and ad networks are you planning to integrate (e.g., AdMob, OfferToro, Pollfish)? Do you already have in-app purchase products configured in Google Play Console? Should there be a withdrawal/redeem system (e.g., PayPal, gift cards), or only point accumulation for now? Do you need fraud prevention mechanisms (e.g., VPN detection, duplicate account checks)? Best Regards, Srashtasoft Team

Done this exact app. Rewarded ads, survey completion, IAP verification — points system that can't be gamed. Kotlin + Firebase. Balance syncs instantly, persists on reinstall, no data loss. One thing most devs miss — IAP points need server-side receipt validation. Client-side only gets you fake credits fast. Got a points-per-action structure ready or do you need help designing that too?

Hi! Thanks for the detailed breakdown — this is very clear and absolutely doable. Based on your requirements, I’d recommend building the app in Kotlin using Firebase for authentication, realtime database, and analytics to keep things fast and scalable. I can implement a secure rewards system that credits points for surveys, ads, and in-app purchases with proper backend validation to ensure accuracy and prevent abuse. Before starting, I’d like to confirm a couple of details: Do you already have preferred survey providers (e.g., CPX, Pollfish), or should I integrate one? Do you want a simple MVP first, or a production-ready version with fraud protection and analytics from the start? Any UI/UX references or should I propose a clean default design? Once I have this, I can outline the architecture and timeline and get started right away.
