Why I built AppX: to turn a plain-English mobile app idea into a working app people can test on a real phone.
Where it came from
Too many app ideas stay trapped in documents, mockups, and long development estimates before a real user can touch them. I wanted a faster path: describe the screens and behavior, generate a real Expo and React Native app, scan a QR code, and learn from real feedback immediately.
How it got built
AppX has a React web product and a Node.js backend, while every generated mobile project uses Expo and React Native. The difficult part was not drawing screens; it was turning open-ended prompts into a coherent app, keeping chat edits consistent, and delivering a working phone preview while preserving real code ownership. The product has been built iteratively around that generate, test, refine, and export loop.
React and Node.js keep the product in one familiar TypeScript ecosystem. Expo and React Native produce a real mobile app that can be tested quickly on a phone. Postgres and Drizzle handle durable product data, Redis supports real-time work, Docker keeps services reproducible, and the AI providers power generation and chat-driven edits.
How it found users
AppX is early, so I am starting with direct founder conversations, live demos, and carefully chosen product directories. The strongest demonstration is simple: describe an idea, generate the app, scan the QR code, and let someone use it on a real phone. I am not claiming a winning acquisition channel yet; this listing is part of learning where serious mobile-app founders discover new tools.
How it makes money
AppX uses a freemium subscription model. The free plan includes 100 credits each month with no card required, so someone can generate and test a real mobile app before paying. Paid plans are $20, $50, and $100 per month, adding more credits plus shipping features such as ZIP export, custom domains, GitHub two-way sync, always-on apps, and priority support. Paid users can also buy extra credits without changing plans.
What ilyos would do differently
I would focus the earliest version even more tightly on the shortest path from an idea to a working phone preview. The important lesson is that founders do not need another polished mockup; they need something a real user can touch, react to, and improve. Every feature should strengthen that generate, test, learn, and own-the-code loop.
