I’m building a mobile-first reward platform where users can turn spare minutes into real cash. The app must run smoothly on both Android and iOS, and sign-up should be limited to fast phone-number verification—no email or social media logins clogging the flow. Core earning activities are already set: • Watching rewarded video ads • Completing in-app surveys • Playing light, casual games that drip rewards Each action should credit a real-time wallet that the user can check any time. Behind the scenes I need a secure, scalable backend (Firebase, Supabase, AWS Amplify—your call) to store balances, ad impressions, survey completions, game scores, and any anti-fraud logic. A lightweight web admin panel has to let me adjust reward rates, monitor user statistics, and approve or trigger payouts. Deliverables I expect: 1. Production-ready Android (.aab) and iOS (App Store-ready) builds 2. Full source code with clear documentation 3. Live backend and admin dashboard fully connected 4. Short hand-off session or video walkthrough so I can keep things running Please outline the ad networks, survey SDKs, and game framework you plan to use, along with a timeline for delivering an MVP I can test through Google Play Internal Testing and TestFlight. Clean UI, efficient code, and store-compliant builds are must-haves.
