Calling Feature App Development

@mrresearcher99

Hello, I have 10 years of experience building mobile applications for Android and iOS, including marketplace-style platforms, booking flows, user profiles, and payment-based app features. For your astrology consultation app, I would recommend React Native so both platforms can be developed from one maintainable codebase while keeping the UI smooth and responsive. I would build secure user registration, customer and specialist profiles, a searchable specialist directory, wallet/payment flow based on per-minute usage, call session handling, transaction history, and REST API integration with a scalable backend using Node.js or Laravel with MySQL/PostgreSQL. I can share relevant mobile app examples during discussion. Let’s discuss the call workflow and payment logic. Best regards

Hi, **1. Understanding of the project:** I understand you need an iOS developer to build and integrate a reliable calling feature into your application, with a smooth user experience, stable call connectivity, and proper handling of call states and permissions. **2. My solution:** I can develop the calling functionality with a clean, scalable architecture and integrate the required VoIP/calling technology based on your existing app. I’ll handle call initiation, incoming calls, audio/session management, permissions, background behavior, call notifications, error handling, and testing across supported iOS versions/devices. I’ll also ensure the implementation is secure and optimized for production. **3. Questions:** • Is this audio calling, video calling, or both? • Is the existing app built in Swift, Objective-C, Flutter, or React Native? • Do you already have a preferred VoIP/API provider or backend? I’d be happy to review your existing app and discuss the implementation. **Please initiate chat with me here in the Freelancer chat.** Regards, Amit

Hi, A specialist consultation app like Astrosage needs more than profiles and payments—the calling flow and per-minute billing must feel seamless and reliable for both users and specialists. We can build the experience around that core requirement. I’d recommend Flutter for a single iOS and Android codebase, with Laravel/PHP for the backend and MySQL for structured user, specialist, wallet, and transaction data. For calling, we can integrate a reliable real-time voice service with server-side call tracking to calculate the ₹5/minute charges accurately. The app can include secure registration/login, user and specialist profiles, specialist categories and search, availability status, wallet/payment integration, call initiation, call duration tracking, automatic balance deduction, transaction history, and notifications. An admin panel can manage specialists, users, rates, transactions, and platform settings. I’ll keep the architecture modular so features such as ratings, chat, scheduling, promotions, or additional consultation types can be added later without major redevelopment. I’d be happy to discuss your vision and suggest ideas to make Fabulous Garments stand out online. Looking forward to working with you! Best Regards, Prachi Webix Infotech

@priyanshuk879

Hi, I can build an iOS and Android app similar to Astrosage with a clean and simple user flow. I’ll set up user registration, profiles, and a searchable specialist directory. The calling feature can support the ₹5/minute rate with proper call tracking. I’ll integrate secure payments and manage the required wallet/balance flow if needed. The app will be designed for smooth use on both Android and iOS. I’ll also build the specialist side so they can manage their profile and availability. The backend will be structured to handle users, specialists, calls, and transactions reliably. I’ll keep the UI simple so users can quickly find a specialist and start a call. I can share relevant mobile app work and discuss the preferred calling/payment setup. Ready to start Immediately.

@hassanak07

Hi Client! The main challenge is building a reliable specialist calling platform where users can easily find experts, pay per minute, and have smooth calls on both iOS and Android. The payment and call-duration tracking must also stay accurate so the ₹5/minute billing is handled correctly. I’ll build a clean mobile experience with registration, profiles, specialist directory, secure payment processing, and real-time calling. I can use Flutter with a PHP backend to maintain one scalable codebase while keeping the iPhone and Android experience smooth. The backend will track call sessions and billing securely, with proper user and specialist management for future features. Do you already have a preferred calling provider/API, or should I recommend the most reliable option for per-minute billing? Start /Open chat now.

@ArpitRahi

Hi, I can build this — a specialist-consultation calling platform with per-minute billing and payment processing is a solid full-stack + mobile build I can execute end-to-end. To make this low-risk: I'll build a free 2-week proof-of-concept — core user registration + specialist directory with a working call initiation flow — before any commitment or full payment. My approach: • Stack: Flutter for cross-platform iOS/Android from a single codebase, backend on Node.js/FastAPI with a real-time calling layer (Twilio Voice or Agora for reliable VoIP calling). • User & specialist profiles: Clean registration/onboarding for both sides, specialist directory with filtering (category, availability, ratings). • Per-minute billing: Real-time call duration tracking tied to wallet/balance deduction at ~₹5/minute, with pre-call balance checks to prevent mid-call cutoffs from failed payments. • Payment processing: Secure gateway integration for wallet top-ups and specialist payouts. • Call reliability: Built for call quality and reconnect handling, since consultation calls need to feel dependable. Background: Founding engineer, 6+ years shipping production mobile and full-stack systems — happy to share relevant work. Timeline: 20-25 days for a fully working, tested build. Ready to scope the POC and start immediately.
