I need a complete, production-ready platform that lets anyone request an OTP to any virtual phone number and view the code instantly—no login screens, no sign-ups. The service must work in two places: a responsive web interface and a companion mobile app. Core flow 1. Visitor chooses one of an unlimited pool of numbers shown on the screen. 2. They enter that number wherever they need an SMS-based verification code. 3. Within a second of the sender delivering the SMS, the OTP appears in the web view and inside the mobile app, auto-refreshing in real time. Key technical needs • SMS-based verification only; email isn’t required. • Zero end-user authentication; the pages and app open straight to the inboxes. • Unlimited numbers available at all times, recycled automatically when carriers release them. • Sub-second polling or web-socket push so new messages surface instantly. • Clean, lightweight UI that groups messages by number and auto-clears old codes after a configurable period. Deliverables • A live web platform deployed on my domain. • Android and iOS builds (native or cross-platform) that mirror the web functionality. • Admin panel or script to add/remove numbers and monitor SMS traffic. • Full source code with setup documentation so I can redeploy if needed. Acceptance criteria • Any SMS sent to the displayed numbers is visible in both interfaces in ≤1 second. • No login is ever prompted. • System reliably handles high concurrent traffic without dropping messages. If you already have experience hooking Twilio, Telnyx, Nexmo or similar gateways to real-time web/mobile front ends, this should be straightforward. Show me a quick demo or repo link with similar functionality and we can get moving right away. Remember I(the owner) will not be charged for any penny while creating this app and after the production while using the app I should not be charged
