You're looking to build a lightweight video-calling app that prioritizes connection stability and call quality. The focus on phone-number verification without email or social logins means we need a solid OTP workflow that’s both user-friendly and secure, those features are really important. I can implement the necessary features using Swift and Kotlin or React Native, depending on your preference, while making sure the app performs well across both iOS and Android. And I can complete the work first and have it ready for you to test before any payment or milestone is set. You can see the final product in action and only proceed once you're satisfied, this way, there's no risk on your end. I’m ready to start immediately and I can deliver production-ready builds along with all the required documentation. My bid for this project is 24999 INR, just to let you know. Rajavel Specializing in mobile app development with a focus on real-time communication, I have a lot of experience in this area.

Hi, The main challenge here is not the video UI—it’s making one-to-one calls recover correctly from real-world network drops, backgrounding, incoming-call notifications, and signaling changes without leaving either user in a broken call state. I’d build the first release in Flutter with a proven RTC layer, keeping call state, signaling, OTP authentication, and notifications modular so group calls and screen sharing can be added later without restructuring the core. I’ll also validate the encryption approach against the chosen RTC provider rather than treating transport encryption as automatically equivalent to true end-to-end encryption. I have 10+ years of mobile development experience with Flutter, iOS, Android, Firebase, and API integrations.

The core challenge here is delivering crystal-clear one-to-one calls with stable connections and low latency, while keeping the architecture lightweight enough to expand into group calls and screen sharing later. I’d build this with Flutter for a shared iOS/Android codebase and a proven real-time engine such as WebRTC, Agora or Twilio. ✅ Flutter iOS + Android with native-feeling UI ✅ Phone OTP authentication with auto-read where supported + manual fallback ✅ One-to-one video/audio calling with efficient bandwidth handling ✅ Network-drop detection, reconnection and graceful call states ✅ Push notifications for incoming calls ✅ Local/cloud call history ✅ Encrypted audio/video transport with secure authentication and signalling ✅ Lightweight backend for OTP, users and call signalling ✅ Modular architecture ready for future group calls/screen sharing ✅ Real-device testing across recent iOS/Android versions ✅ Production builds, source code, README, setup scripts and test report I’d structure development as UI → OTP/auth → signalling → calling engine → notifications/history → security → QA → release, with call-quality and edge-case testing throughout. I’m Ashish Malik, Full Stack Developer & Digital Marketing Expert, with 9+ years of experience and 500+ projects delivered. Let’s start a chat and turn the calling flow into a stable, polished first release.

@ibrahimsoft004

Hi, I can develop your lightweight iOS and Android video-calling app with a strong focus on low latency, stable connections, and a polished user experience. I recommend Flutter for a shared codebase, integrated with WebRTC/Agora for high-quality one-to-one video and audio calls. I can implement phone OTP authentication, incoming-call push notifications, network reconnection handling, call history, secure encrypted communication, and a lightweight backend for authentication and call signaling. The project will be built with a clean, modular architecture so future features such as group calling and screen sharing can be added easily. I’ll deliver production-ready iOS/Android builds, complete source code, backend setup, documentation, and testing reports. I’m available to start immediately and can handle development through App Store and Google Play deployment.

@WebXcellance

Hi there! I am ready to build your lightweight 1-to-1 video calling application for both iOS and Android, with a strong focus on call quality, low latency, reliability, and clean architecture. I have 5+ years of development experience and can work with React Native, Node.js, WebRTC, Firebase, WebSockets, REST APIs, push notifications and mobile authentication. For the first release, I can implement phone-number OTP authentication, 1-to-1 audio/video calling, incoming call notifications, network-drop/reconnection handling, local or cloud call history, and a lightweight backend for authentication and signalling. I would structure the code modularly so future features such as group calling and screen sharing can be added without rewriting the core application. I will also provide production-ready iOS/Android builds, source code, setup documentation, and a test report covering call quality, edge cases and security considerations. For the calling layer, I can evaluate WebRTC, Agora or Twilio based on the required reliability, scalability and cost. I can start immediately. My estimated budget is ₹80,000–₹1,20,000 depending on the final calling architecture and backend requirements. Let's discuss the required platforms, preferred calling provider, OTP provider, and expected user scale on chat. Thanks, Sachin.

@letscms

Hi, I can build your cross-platform video calling app with Flutter and WebRTC, Agora, or Twilio. I have already developed and published BindasLive, a live streaming and video calling platform with real-time video/audio communication: BindasLive on Google Play I’ll implement phone OTP login, 1-to-1 calls, network-drop handling, push notifications, call history, and secure encrypted communication. I’ll keep the architecture modular for future group calls and screen sharing, with production-ready iOS/Android builds, backend, source code, and documentation.

@albertc1996

Hi, Building a low-latency 1-on-1 video calling app requires combining Flutter/React Native with WebRTC/Agora and native VoIP push triggers (Apple PushKit for iOS and FCM High-Priority for Android) so incoming calls wake up locked devices instantly. Here is the technical approach for your v1 release: Auth & Signaling: Firebase Phone Auth (OTP with auto-read fallback) paired with a lightweight Node.js/WebRTC signaling server or Agora RTC SDK. Real-Time Call Engine: WebRTC / Agora integration with adaptive bitrate management, ICE candidate exchange, automatic network reconnection, and end-to-end media encryption. Incoming Call UX: Native CallKit (iOS) and ConnectionService/FCM (Android) integration so incoming calls trigger a full-screen incoming call UI even when the app is in the background or killed. Call History & Storage: SQLite / Hive local storage for offline call logs and duration history. Modular Architecture: Clean architecture separating the UI from the WebRTC signaling service, keeping the code ready for v2 group calls and screen sharing. Deliverables include production iOS/Android builds, source code, signaling/PaaS backend setup, and a test report covering latency and reconnects across 3G/4G/Wi-Fi. Ready to discuss your preferred RTC provider (WebRTC self-hosted vs Agora) and begin setup.

@mikes126

I will build a lightweight cross-platform 1-to-1 video calling app using Flutter/React Native with WebRTC, Agora, or Twilio, focusing on low latency, stable calls, adaptive bandwidth, and secure media encryption. Phone authentication will use OTP with automatic SMS detection where supported and secure manual fallback, with proper session/token handling. The calling flow will include call signalling, incoming-call push notifications, call accept/reject, reconnection after network drops, microphone/camera controls, and graceful handling of poor connectivity. I will implement local/cloud call history and structure the backend into modular authentication, signalling, notification, and user services so future group calls or screen sharing can be added without major rewrites
