Cross-Platform Video & Voice Calling App (Similar to Friend App)

@kamran2012

Hi there, I will build your video and voice calling app in Flutter with a coin-based calling system, covering registration, real-time WebRTC calls, automatic coin deduction per minute, and a full admin panel for managing users, payments, and settings. For the calling wallet, I will handle coin purchase via Stripe or Razorpay and deduct coins server-side (not client-side) so users cannot bypass the charge. On a similar calling app, this approach eliminated billing disputes almost entirely. Questions: 1) Do you have a preference between Firebase and a custom Node.js backend for the real-time signaling? 2) Should coin packages be fixed amounts, or do you want users to enter a custom top-up? I am happy to share two relevant examples in our chat. Send me the details and I will map out the first milestone. Looking forward to potentially working together. Thanks, Kamran

Hi, I can develop your cross-platform Friend App–like application for Android & iOS using Flutter/React Native with a secure, scalable backend. I have already built similar platforms with features like user auth (phone/email/social login), real-time voice/video calling, in-app wallet/coin systems, payment gateway integration, and admin dashboards with full control over users, transactions, and analytics. Approach: Requirement finalization & UI/UX flow System architecture (app + backend + DB) Development (auth, profiles, calls via WebRTC/Agora, wallet system) Payment integration & coin deduction logic Admin panel development Testing, optimization & deployment I’m open for long-term collaboration and can ensure clean, scalable, production-ready code. Thanks

I have solid experience building Flutter-based video and voice calling apps integrated with Agora or Twilio, making me well-suited for your Friend App-inspired project. I understand both the social and monetisation layers you need. I'll build: user registration (Phone/Email/Google), rich profiles, real-time 1-to-1 voice and video calling via Agora SDK, an in-app coin/wallet system where users purchase coins to make calls with automatic per-minute deduction, secure payment gateway integration, call history and coin transaction logs, push notifications, and a full admin panel for user management, coin configuration, payments, and reports. The codebase will be clean, well-structured, and maintainable with a scalable backend (Node.js + Firebase/PostgreSQL). I'm open to a long-term collaboration. Can share similar apps from my portfolio on request. Ready to start immediately. Regards, Harsh Thoriya

Hello, I have 10 years of experience developing scalable mobile applications with React Native, real-time communication, secure payment integration, and custom backend solutions. I can build an original, high-performance app inspired by the Friend App while ensuring a modern UI and clean, maintainable architecture. I recommend React Native for the mobile app, Node.js for the backend, Agora/WebRTC for voice and video calling, and a secure payment gateway with an integrated wallet and automated coin deduction. The solution will include authentication, user profiles, transaction history, push notifications, and a comprehensive admin panel to manage users, payments, coins, and reports. I can share similar mobile application projects, my portfolio, recommend the complete technology stack, provide a realistic milestone-based timeline, competitive project cost, and reliable post-launch support for long-term collaboration. Best regards

Your coin deduction logic will fail if users lose network mid-call - you'll either overcharge or undercharge unless you implement server-side call state tracking with WebRTC session monitoring. This creates revenue leakage and user disputes that kill retention. Quick question - are you planning real-time billing per second or fixed-rate packages? And what's your expected concurrent call volume at launch versus 6 months out? These numbers determine whether you need WebSocket infrastructure or can start with simpler polling. Here's the architectural approach: - FLUTTER: Build with GetX state management and Agora SDK for sub-200ms call latency across 190+ countries, integrated with Firebase for real-time coin balance sync during active sessions. - PAYMENT GATEWAY INTEGRATION: Implement Stripe with webhook verification and idempotency keys to prevent double-charging, plus Razorpay as fallback for Indian market penetration. - BACKEND DEVELOPMENT: Deploy Node.js microservices on AWS ECS with Redis caching for coin transactions and PostgreSQL for call records, ensuring ACID compliance during concurrent deductions. - ADMIN PANEL: Build React dashboard with role-based access, real-time analytics on call duration vs revenue, and automated fraud detection for abnormal usage patterns. - PUSH NOTIFICATIONS: Configure FCM with topic-based subscriptions for call invites and low-balance alerts, maintaining 95%+ delivery rate. I've built 2 similar calling platforms that processed 50K+ paid minutes monthly without payment disputes. Let's schedule a 15-minute technical call to validate your monetization model before architecture lock-in.

Hi, I'd be excited to help build a premium cross-platform mobile application inspired by the Friend App while delivering a unique identity, polished user experience, and scalable architecture. The application will include secure user authentication, detailed user profiles, one-to-one voice and video calling, an integrated coin and wallet system with automatic balance deduction during calls, secure payment gateway integration, transaction history, push notifications, and a comprehensive admin panel to manage users, payments, reports, app settings, and virtual currency. The codebase will be clean, well-documented, secure, and built with future scalability in mind. Let's connect! Thanks, Pavan

@techsty2014

Good to see this project, We will build your cross-platform calling app in Flutter: video and voice calls via WebRTC, a coin wallet with per-minute deduction, and a full admin panel. For the coin system, we will track balances server-side and validate each deduction through the backend. This prevents client-side tampering and keeps transaction records accurate for both users and admins. A couple of quick things to confirm: 1) Which payment gateway do you prefer (Stripe, Razorpay, or another)? 2) Should coin packages be fixed tiers, or do you want users to enter custom amounts? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to potentially working together. Thanks, Faizan
