I’m building a colorful, vibrant social-networking experience that launches simultaneously on Android and iOS. Core features are already mapped out and I need the complete app—from polished UI to production-ready back-end—delivered as one seamless package. What the user journey must feel like • Fast, friction-free onboarding with three authentication paths: classic email + password, phone number OTP, and Google OAuth. • A rich profile area where people can update bio, photos, interests, and visibility settings at any time without leaving the main flow. • Real-time text chat and photo sharing available to every registered user, powered by a reliable socket solution. • The big draw: HD broadcasting and one-to-one video calls. Streaming quality should auto-adapt to network conditions while keeping latency low. • A virtual gift system and a coins/credits wallet. Users top up through in-app purchases, then spend credits on premium video rooms, animated gifts, or visibility boosts. A running ledger has to show every credit in and out so there’s never confusion about where money goes. • A simple, delightfully clear purchase flow that satisfies both Google Play Billing and Apple’s in-app purchase policies. Visual style The interface should pop—think bold color gradients, playful iconography, and smooth micro-animations that keep the energy upbeat without sacrificing clarity. Scope you’ll own – Design hand-off files (Figma/Sketch/Adobe XD) reflecting the colorful theme – Cross-platform build (Flutter, React Native, or separate native stacks—whichever you recommend for best video performance) – Secure back-end with account, chat, media, wallet, and ledger services, plus admin tools for user reports and content moderation – Integration of streaming/RTC tech (Agora, Twilio Live, or equivalent) with adaptive bitrate – Full in-app purchase implementation and sandbox testing on both stores – Deployment scripts and store-ready builds, including TestFlight / Google Internal Testing uploads – Post-launch support to squash any critical bugs that appear in the first month Acceptance criteria 1. A tester can register by email, phone OTP, or Google; verification emails/SMS arrive in under 30 sec. 2. Two users on 4G networks can start a video call with under 500 ms latency and stable 720p. 3. Credits purchased through the store appear instantly in the wallet and every spend is logged in the ledger view. 4. App passes Apple/Google review without policy flags for payments or user-generated content. If this build matches your wheelhouse—especially if you’ve shipped live-streaming or wallet-based apps before—let’s get started.
