AI Mobile App Developer | React Native | OpenAI Realtime | Voice AI Hi, I really like this concept because the combination of a talking AI character, live transcription, quizzes and storytelling can make language practice feel much more natural than a standard learning app. I can build the complete iOS and Android experience with a customizable AI character that has real-time voice conversations, transcription, quizzes and interactive stories. I’ll also keep the architecture flexible so Spanish and Chinese can be added later without rebuilding the core system. For engagement, I’d suggest a simple system of XP, streaks, conversation progress and achievements so the gamification supports learning rather than distracting from it. Relevant AI work: ⭐ Dolphin AI SaaS Built using Lovable + Codex. ⭐ AI Sports Prediction — Built using Lovable, Codex, ChatGPT, Gemini and n8n. ⭐ AI Voice/Agent System I have also worked with ElevenLabs Conversational AI for voice-based AI agents and automated workflows. My AI development stack includes Claude, Codex, Cursor, Antigravity, ChatGPT, Gemini, ElevenLabs and n8n, depending on the project requirements. I can handle the UI/UX, mobile development, backend, AI integration, subscriptions, analytics, testing, store builds and documentation. I’d be happy to discuss the character and conversation experience and start with the first MVP milestone. Thanks! Ashraf K

@HamparProd

Hi, I can build this as a production-ready Flutter app for iOS and Android with the AI conversation experience as the core, not a text chatbot with voice bolted on afterward. I recommend Flutter + Supabase/PostgreSQL with a lightweight backend for profiles, learning progress, subscriptions, analytics and secure OpenAI session/token handling. OpenAI Realtime/Voice will power low-latency spoken conversations with streaming transcription and character responses. I’ll structure lessons separately from the AI orchestration layer so Spanish, Chinese and additional learning modes can be introduced later without rebuilding the app. Phase 1 would include customizable AI character interaction, English conversation practice, quizzes, interactive stories, progress/history and a lightweight XP/streak system. I’ll also handle subscription integration, error/reconnect states, usage controls, analytics, QA and store-ready builds. Fixed price: $2,350 USD Timeline: 30 days Complete source code, documentation and demo walkthrough are included.

@Hubready

Hello!, I am a Florida-based senior software engineer(frontend, backend, ecommerce, etc) with about 15 years of experience building production-grade mobile apps, AI products, and scalable APIs. I read your AI language app description carefully, and I understand the goal is not just a chatbot app, but a real learning platform for iOS and Android that feels engaging, reliable, and actually helps users improve. I’ve built AI-driven apps with React Native, Flutter, Node.js, Python, and OpenAI-style integrations, and I’d approach this in practical phases: 1) lock the core learning flow and MVP features 2) build the AI chat + lesson logic 3) create clean iOS/Android UI 4) test, tune, and prepare for launch A few relevant examples of my work: - a language coaching app with AI prompts and progress tracking - a multilingual education app with flashcards and streaks - a SaaS mobile companion app with real-time sync - an AI assistant dashboard for automated user support Could you please clarify the following questions to help me better understand the project? 1) What are the must-have MVP features for v1, and what can wait for phase 2? 2) Do you already have the lesson content, prompts, and app flow, or should I help shape that too? 3) Should the AI focus on free-form conversation, structured lessons, or both? I’m serious about the details because that’s usually what separates a polished app from a rushed one.
